This standard is equivalent to API Spec 4F <Specifications for Masts and Substructures for Drilling and Well Repairing> (2nd Edition, June 1, 1995). When this standard is equivalent to API Spec: 4F, the sin page, "Special Notes" and Appendix C "API License Marking Instructions" of API Spec 4F are deleted.
The equivalent adoption of API Spec 4F can make the design and manufacturing standards of my country's oil drilling and well repairing derricks, bases and overhead cranes in line with international standards and foreign advanced standards, so as to meet the requirements of international trade, technical and economic exchanges, as well as the implementation and adoption of international standards and foreign advanced standards.
When this standard is equivalent to API Spec 4F and converted into this industry standard, the entire text of API Spec 4F is adopted, and its comprehensive writing format and method are retained. The Chinese standards equivalent to the relevant referenced standards in API Spec 4F are explained in the form of annotations. Compared with SY5025-91 "Derricks and Bases for Oil Drilling Rigs", this standard adds chapters such as factory materials, welding requirements and quality control, and deletes the method of indicating the model of derricks and bases and the content of technical parameters of oil drilling rig derricks and bases. Appendix A and Appendix B of this standard are both standard appendices, and Appendix C of this standard is a prompt appendix.
This standard replaces SY5025-91 from the date of entry into force. This standard is issued by the National Oil Drilling and Production Equipment and! The standard is proposed and managed by the standardization technical committee.

This specification is managed by the API (American Petroleum Institute) Drilling and Well Repair Equipment Standardization Committee. The parts of this specification that have changed from the previous API version are marked with black machine symbols. 1) The effective date of this specification shall be based on the date printed on the cover, and it can be adopted voluntarily from the date of publication. 1) The black bar symbol I of the original specification was deleted during editing. 1 Scope Standard of the People's Republic of China for Petroleum and Natural Gas Industry Specification for Drilling and Well Servicing Masts and Substructures SY/T 5025—1999 Replaces SY5025—91 This standard applies to the design, manufacture and use of tower derricks, portable derricks, overhead cranes and substructures for drilling and well servicing. It includes various provisions on equipment marking, standard ratings, design loads, design specifications, materials, welding requirements, quality control and documentation. Definitions of common terms are included in Chapter 3. 1.1 Purpose 1.1.1 The purpose of this standard is to provide a unified design and assessment method for steel structures used in drilling and well servicing operations for the petroleum industry. This standard applies to all new designs of tower derricks, special derricks, portable derricks and substructures. 1.1.2 Products manufactured to AI'1 Spec 4A, 4D or 4E need not comply with all the requirements of this standard. This standard is intended to meet the requirements of current and future operating conditions (such as deeper drilling, offshore drilling on floating units, and the response to earthquakes, storms and other severe conditions).
1.1.3 This standard is intended to provide manufacturers and users with a common understanding of the ratings and capabilities of various steel structures used in drilling and repair operations.
1.2 Product Specification Levels (PSL)
This standard proposes requirements for two product specification levels. The technical and quality requirements of these two product specification levels are different. PSL1 is the current common practice in manufacturing. All requirements of this standard apply to PSL1 unless otherwise specified as PSL2. PSL2 includes all the requirements of PSL1 plus further quality control requirements. 1.3 Supplementary Requirements (SR)
Supplementary requirements are only applicable when specified by the parties in the contract. Appendix A (Standard Appendix) gives the additional requirements of this standard.

7.1 Allowable stresses
7.1.1 General
The AISC Code for Steel Structures for Buildings should be used as a guide for the design of these steel structures. The allowable stress design section of the code is usually regarded as an elastic design and will be used to determine the allowable stresses. AISC Code for Steel Structures of Buildings, Part 5, Chapter N, "Plastic Design" is explicitly not applicable. Except that current practice and experience do not require compliance with AISC regulations for "Members and Connections Subject to Fatigue Loads", the AIC should be the basis for the final determination of allowable stresses and acceptable stresses. In the individual members of a lattice or truss structure, the stresses caused by elastic deformation and joint rigidity are defined as secondary stresses. These secondary stresses can be taken as the difference between the following two stresses: one is assuming that the joint is completely rigid, and the load acts only on the joint Stress obtained by analysis: Another is the stress obtained by similar analysis based on the node as a hinge. The stress generated by the following factors: eccentric connection of the node, lateral load on the rods between the nodes, or the existence of external moments must be regarded as the principal stress. 7.1.1.1 When the secondary stress is calculated and added to the principal stress of each rod, the allowable stress can be increased by 20%. However, the principal stress shall not exceed the allowable stress value of 7.1.1
7.1.1.2 The ground load and related allowable stress are discussed specifically in 7.4. 7.1.2 Wind and dynamic stresses (caused by floating hull motion) When wind loads and dynamic loads act alone or in combination with the design dead and live loads, the allowable stress may be increased by one third over the stress value specified in 7.1.1, but the required cross-section for this calculation shall not be less than the required load area calculated for the dead, live and impact loads (if any) without taking into account the one-third stress increase. The purpose of this paragraph is to increase the allowable stress by one third for the dynamic loads caused by the floating hull motion, rather than by one third for the wind loads as stated in the AISC Code for Steel Structures of Buildings. 7.1.3 Wire ropes
The size and type of wire ropes shall comply with the provisions of API Spec 9A and API RP 9B: 7.1.3.1 The nominal strength of wire rope assemblies for hoisting and lowering shall not be less than 2.5 times the design load of the hoisting and lowering wire rope assemblies.
7.1.3.2 The nominal strength of the steel wire rope assembly used for the guy rope shall not be less than 2.5 times the design load of the guy rope assembly. 7.1.4 Crane axle
The crane axle, including the fast rope and dead rope pulley support shaft, shall be designed in accordance with AISC "Steel Structure Code for Buildings" (see 7.1.1), except that the bending yield safety factor is at least 1.67. The steel wire rope pulley and bearing shall be designed in accordance with API Spec 8A2), or API Spe: 8C (PSI1 and PSI2) as required by the user. 7.2 Wind load
The wind force shall act on the entire structure. The wind direction that can produce the maximum stress on each component of the structure must be determined and considered. The wind force for various design wind speeds shall be calculated according to formula (1), formula (2) and Tables 1 and 2, that is, the wind force formula:
1) SY 517/--1998 (Shibo Natural Gas Industry Steel Wire Rope Specification) may also be used. 2) SY/T5112-1999 (Specifications for drilling and oil production lifting equipment) 8
