API Foreword
This specification is managed by the API Drilling and Operation Equipment Standardization Committee. The purpose of this specification is to provide roller chain standards suitable for oil well drilling and oil production operations. Most of the technical information related to roller chains and sprockets is taken from ANSI H29.1 "Precision Roller Chains, Sprockets and Accessories" published by the American Chain Association and its published drawings (Chain for Prwcr Transmission and Material Handling). In addition, some of the contents of ANSIB29.1 are required to be referenced in this specification. The performance curves related to chain performance included in this specification are specifically for chains used in oil fields. These materials cannot be found in other publications and the performance tests included in it exceed the basic requirements of other standards or specifications. Due to the wide variety of service conditions and the complexity of the transmission conditions studied, the section on transmission design has been eliminated in this version of this specification. The relevant publication under the jurisdiction of the API Drilling and Operating Equipment Standardization Committee is API Spec 7, Specification for Rotary Drilling Equipment. Conversion values ​​between the U.S. Customary Medium Pressure System and the International System of Units (SI) are given in symbols throughout the text of this specification, for example: 6 in (152.4 tmu). In all tables, the corresponding values ​​in the International System of Units are also given. Formulas and certain relationships are intentionally expressed in U.S. Customary units to prevent confusion with listed values. If the units of the newly calculated values ​​need to be expressed in SI units, the conversion factor is given below the formula. In this specification, U.S. Customary units are preferred in all cases and are used as the standard. Unless otherwise agreed between the supplier and the supplier, the products should be marked with units as required. The conversion coefficient between national and international units is taken from API Publication 2564, which is as follows:
lin-25.4mm (accurate value)
It=0.3048m ((accurate value)
Ilbf4.448222N
Ift-1bf=1.355818Nm
1hjp=0.7456999kw

This standard specifies the code, dimension parameters, requirements, test methods, marking, packaging and sprocket type parameters of standard series and heavy-duty series roller chains for oil.
This standard is applicable to the manufacture and testing of oil drilling rig transmission roller chains (hereinafter referred to as chains): See Appendix T) (Note)
2 Requirements
2.1 Chain Code
The chains in this standard are marked with the following codes.
Number of rows (marked on the top and bottom of the chain plate)
Heavy-duty series (omitted for standard chain)
Ordinary chain with sprockets (other numbers indicate characteristics) Chain number (number of 1/81n indicates pitch)
Through: 160H-6 indicates a pitch of 50.8mm, a heavy chain with rollers, and 6 rows. 2.2 Heavy-duty series chain
The pitch of the heavy-duty chain is 19.05mm (3/4in) or more. Its chain pole thickness is different from that of the standard series and is only used for low-speed and high-load conditions.
2.3 Small parameters
2.3.1 See Appendix A (Standard Appendix) for the main dimensional parameters of the chain. 2.3.2 See Appendix B (Standard Appendix) for the type parameters of the sprocket. 2.1 Chain length tolerance
The measurement load refers to the load applied when measuring the chain length. For single-row and multi-row chains, the value is 1% of the minimum ultimate tensile load, which is between 139.0N (31[bf) and 5004.0 (1125[bf). The minimum chain segment measurement length is 304.8mm (12in). Under the standard measurement load, the measured length of a new chain should be less than or equal to the sum of the measured length of the chain segment and the relative value listed in Table 1. 2.5 Tensile load
2.5.F Single-row chain
Approved by China National Petroleum Corporation on December 28, 1997, implemented on June 1, 1998
SY/T5595-1997
Standard and heavy-duty series single-row chains that meet the requirements of this standard shall have a minimum ultimate tensile load, which shall be greater than the length tolerance of the iron bars listed in Table 2
System length tolerance
Multi-row chains
For multi-row chains, the minimum ultimate tensile load refers to the minimum load that may damage a chain that has not been used and is not damaged when it is only subjected to tension (see Table 2). The minimum ultimate tensile load is not the load that the chain may bear when in use, it only indicates the tensile load characteristics of the chain.

The effective values ​​and test results specified in the dynamic load test cannot be used as the effective characteristic values ​​in the actual design. ! The dynamic load test is a kind of breaking test. If the chain does not fail at the end of the test, it may be damaged and cannot be used. The minimum tensile load test specified in the SY/T5595-1997 standard is a destructive test. All samples that have undergone this test should be used again in practice regardless of damage or loss: 2.6 Minimum push-out force The minimum force required to remove a single pin or sleeve in a single chain. It shows the shape of the hole limit on the chain plate and the firmness of the pin and sleeve (matching with the chain plate). The pressing force between the pin and the outer link plate, and between the sleeve and the inner link plate is shown in Table 23. Test method

3.1.5.1 Pin shaft and milling plate
For chain links assembled in the form of pin riveting, the riveted parts should be removed first when disassembling. Be careful not to damage the surface of the chain plate. Remove one shovel plate first. Do not damage the integrity of the connection between the pin and the remaining chain plates during the disassembly process. The remaining chain plates should be placed on a hydraulic or mechanically controlled testing machine. Put the pin The shaft is placed in a water position and supported. Prevent the chain from moving when pressure is applied. Slowly apply an axial load to the top of one pin and press the pin out in the direction of the chain. The applied pressing force should not be less than that specified in Table 2. 3.1.5.2 Sleeve and inner link plate
The method for removing an inner link plate is the same as that for removing an outer link plate. Remove the two rollers on the sleeve, place the chain plate with two sleeve arrows on the testing machine and support it. Slowly apply an axial load to the end of one sleeve and press the sleeve out of the chain plate. The applied pressing force should not be less than that specified in Table 2. 3.1.6 Tensile load
Each batch of chain should be subjected to a tensile load test before leaving the factory: a) The error of the net load indication of the testing machine should not exceed 1%; h) The test specimen has a chain segment with at least 5 sections (inner links at both ends): +

) The design and installation of the joint should ensure that the load on the specimen is uniform and the added load is reduced as much as possible;) If the failure occurs on the chain link connected to the joint (not the inner chain), the side frame is invalid: another sample should be selected for testing. 3.1.7 Sampling of tensile load specimens
