Glass plant, piping and fittings-General rules for testing, handring and use
Glass plant, piping and fittings-General rules for testing, handring and use This standard specifies the general rules for the inspection, installation and use of glass equipment, piping and fittings. This standard does not cover the design of glass components. HG/T 3176--1998
131 IS0 3586: 1976
When installing equipment or pipelines, relevant safety operating procedures should be followed. For pressurized equipment, relevant pressure vessel operating procedures should also be followed. 2 Referenced standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards. HG/T8115--1998 Borosilicate Glass 8.3 Performance 3 Materials
The physical and chemical properties of the structural materials of the glass filling components shall comply with the provisions of HG/T3115. The materials used for the gaskets in contact with the working fluid shall be used as described in the manufacturer's instructions. 4 Inspection
4.1 Factory inspection
All parts of equipment used as pressure vessels shall be subjected to routine pressure inspections by the manufacturer. The pressure inspection shall be carried out by hydraulic pressure test.
All pressure tests shall be recorded in detail to enable review of past tests and to provide the user with a certificate of inspection. 4.2 Inspection by the user
4.2.1 The user shall not conduct on-site pressure tests without the participation of the supplier or a department recognized by both parties. 4.2.2 When the assembly of components is subjected to on-site pressure tests, the pressure test shall also be adopted. When the equipment is connected, the air in the system shall be exhausted to ensure that the device is not affected by various stresses caused by assembly or connection of pressure test equipment. The total pressure on the entire assembly shall not exceed its maximum working pressure. The equipment shall also have an appropriate shielding layer to protect the operator. Note: When measuring the pressure of the entire system at a certain point, the indicated pressure value deviates from the pressure of the entire system, and the difference is the static pressure head of the liquid. Therefore, if the pressure slope is not taken at the lowest point of the assembly, it is estimated that the pressure at this point will be higher than the indicated value. 4.2.3 The static pressure head of the liquid in the vertical pipe above the assembly shall be used as the hydraulic source. If this is not possible in practice. For the sake of reliability, a hydraulic pump can be used.

4.2.4 In fact, if the hydraulic test method cannot be used, an air with a water seal (as shown in Figure 1) with a pressure of 10KPa can be used for testing, and the joints can be checked for leakage. If a leak is found, the pressure should be reduced before the equipment starts working. When used under vacuum conditions, the equipment should be evacuated, and any leaks can be detected by the pressure increase relative to the known internal volume. 4.2.5 The test method should have a detailed written report, the purpose of which is to conduct the test work and subsequent safe operation, so that both the user and the manufacturer can record the test process. After the test, any necessary changes or adjustments to the equipment must be recorded in the report. 5 Installation
From the user acceptance point of view, this standard explains the installation of relevant glass equipment. Damage to the glass surface will affect the strength of the component and should be prevented.
5.1 Acceptance and Storage
5.1.1 Glass equipment should be accepted by the user and properly protected for storage. After opening the packaging, the glass equipment should not be placed on any hard surface to avoid damage. Do not let the cylindrical components roll. 5.1.2 Larger components are too heavy to be handled and should be handled by several people or with appropriate machinery. Many larger and heavier components are delivered in specially designed packaging that is easy to load and unload mechanically. 5.1.3 All components should be stored separately. Heavy components should not be stored on top of lighter components. 5.2 Assembly
5.2.1 Glass components should be placed at the installation site so that each component can be easily identified and unnecessary handling can be avoided. When handling glass equipment with protruding parts such as side tubes, if possible, all protruding parts should be visible to reduce the risk of accidental collision with obstacles. Side tubes or any other protruding parts should not be used to lift glass parts. 5.2.2 Glass equipment should usually be transported upright, otherwise it will be dangerous when slender components encounter obstacles such as steel frames at bends. All unnecessary obstacles should be cleared at the installation site, and the site should be checked to ensure that electrical equipment and other auxiliary facilities do not hinder the installation work. Attention should also be paid to the legally necessary facilities related to the installation site, and effective safety protection devices should be available. 5.2.3 The assembly of glass equipment should be carried out under the command of a dedicated person who is proficient in installation technology and familiar with the safety regulations and legal requirements of the installation site. All other installation personnel should receive training on the installation of glass equipment. The manufacturer should provide technical information on the installation. All supports for glass equipment and pipes should meet the requirements of the manufacturer. 5.2.4 It must be recognized that unrestricted telescopic hoses will generate forces under pressure increase or decrease, which will cause the connected components to break. When the telescopic hose of the pipeline is fixed in its final position after installation, the equipment should be prevented from moving before it is under pressure. When transporting and installing components designed for upright use, such as heat exchangers, care should be taken not to turn them upside down. 5.3 Disassembly
5.8.1 When disassembling the coupling assembly, the support of the auxiliary assembly should be removed. It should also be noted that the remaining equipment has its proper support. Before completing the entire disassembly work, these auxiliary assemblies should be carefully placed. All removed components should be carefully cleaned with appropriate detergents and thoroughly inspected for damage or surface defects.
5.3.2 The serpentine water pipe or steam pipe of the heat exchanger should be cleaned. It can be first washed with dilute hydrochloric acid and then with water circulation to flush the outer wall of the serpentine pipe and the sleeve. The cleaning method should be determined by the working fluid used. 5.3.3 If a component needs to be repaired by the manufacturer, the user must guarantee in writing that the component has been cleaned and there is no residual working material.
6 Use
6.1 Operation
The operation of any equipment or piping system must comply with the scope specified in the design of the system. When a user uses components from the manufacturer's product catalog to design a system without signing a contract with the manufacturer, its operating condition range should not exceed the range specified for each component in the manufacturer's product catalog. The operating instructions shall include instructions for the operating procedures, including the start-up, operation and shutdown of the equipment. The critical parameters for shutdown and emergency measures shall be clearly specified.
HGT31161998
When the process may cause the pressure to exceed the design pressure, a pressure reducing valve, explosion-proof diaphragm alarm device, etc. shall be installed at the appropriate position of the equipment for protection.
62 Safety Measures
Within the limits specified by the manufacturer's design, glass equipment and pipeline components are very strong and durable. As long as they are not in a special corrosive environment, their service life is long. Improper installation and use, and unreasonable design of structures or supports may cause damage to components. Before the work of installing the equipment is carried out, a certificate of conformity shall be produced where appropriate. Protective devices shall be added to any components or devices that may cause abnormal risks to prevent unexpected dangers and personal accidents. For this purpose, transparent or other appropriate shielding shall be used.
6.3 Maintenance
A preventive maintenance plan shall be established for each device, in which detailed provisions shall be made for regular maintenance and inspection. Maintenance of glass equipment is usually minimal.
When conveying fluids that corrode glass, the thickness of the glass must be checked at critical locations. When conveying other corrosive or hazardous fluids, the condition of critical connection points should also be checked frequently. When static electricity is encountered at the equipment installation site, it is very important to check the continuity of the grounding system. 6.4 Thermal conditions
Except for equipment specially designed to meet larger temperature differences, such as heat exchangers, the temperature difference caused by the working conditions in the equipment, that is, the difference in fluid temperature measured on the two sides of the glass surface, must not exceed 120°C. Glass can withstand heating rates much faster than the cooling rate, and it is usually not necessary to limit the heating rate. Actual cooling should be avoided. For example, cold water must be prevented from splashing onto a hot equipment. Under freezing conditions, water-cooled heat exchangers and other water-containing equipment are as dangerous as equipment made of other materials.
6.5 Mechanical conditions
The overall strength of a glass component is related to its surface condition. Mechanical damage will reduce its strength. Mechanically damaged components are only allowed to be used for a short period of time. Glass components that are used for a long time should be protected from surface damage. Surface damage may be caused by a variety of factors, including the following: a) Impact damage caused by careless transportation
b) Operators touching or working close to the equipment; e) Collisions or scratches caused by glass components contacting other materials during assembly; d) Welding of gold mesh close to glass components; e) Scratches caused by scraping deposits from the glass surface or rubbing against the glass container wall due to improper positioning of the stirrer and insertion tube.
6.6 Static Electricity
Chemical equipment made of borosilicate glass is far less harmful due to static electricity than conductive equipment. If the fluid velocity is kept below 1m/s, the passband can prevent the generation of static electricity. When the working fluid resistance is less than 10% gcm, static electricity will not occur. Blockages in the pipeline system and contaminants, including air and water, in the working fluid may increase static electricity.
In case of danger caused by static electricity, preventive measures should be taken, including grounding of all associated and nearby metal parts, grounding of the outer surface of each glass component, and general protection such as wearing work clothes. The resistance of the grounding system should not exceed 10°, and all national regulations on preventing static electricity hazards must be followed. 7 Manufacturer's instructions
The technical indicators of each component determined in the standard must be explained by the manufacturer. The rules for the use of these components should be strictly followed. The manufacturer's name or registered trademark should be durably printed on each glass component. 3

The overall strength of a corrugated glass component is related to its surface condition. Mechanical damage will reduce its strength. Components with mechanical damage are only allowed to be used for a short period of time. For glass components used for a long time, care should be taken to prevent surface damage. Surface damage may be caused by a variety of factors, including the following: a) Impact damage caused by careless transportation
b) Operators touching or working close to the equipment; e) Collisions or scratches caused by glass components contacting other materials during assembly; d) Welding of gold mesh close to glass components; e) Scratches caused by scraping deposits from the glass surface or abrasions caused by improper positioning of the stirrer and insertion tube against the wall of the glass container.
6.6 Electrostatic Effects
The hazards caused by static electricity in chemical equipment made of borosilicate glass are far less than those in conductive equipment. If the fluid velocity is kept below 1m/s, the passband can prevent the generation of static charges. When the resistance of the working fluid used is less than 10% gcm, static electricity will not occur. Static charge may increase when there is a blockage in the piping system and when there are contaminants, including air and water, in the fluid of the working process.
In the case of danger caused by static electricity, preventive measures should be taken, including grounding of all associated and nearby metal parts, grounding of the outer surface of each glass component, and general protection such as wearing work clothes. The resistance of the grounding system should not exceed 10°, and all national regulations on preventing static electricity hazards must be observed. 7 Manufacturer's instructions
