What is the full content of the Ministry of Petroleum Industry Industry Industry Standard SY T5037 2

Spiral welded pipeSpiral welded pipe: It is to roll low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank according to a certain spiral angle (called forming angle), and then weld the pipe seam together, which can produce large-diameter steel pipes with narrower strip steel. Spiral welded pipes are mainly used for oil and gas transmission pipelines, and their specifications are expressed by outer diameter * wall thickness.

Spiral welded pipes are single-sided welded and double-sided welded, and the welded pipes should ensure that the hydraulic test, tensile strength and cold bending performance of the weld meet the regulations. Steel pipe specifications: minimum 400, maximum 3048 Execution standard of spiral welded pipe:

Standard No.: SY T 5037-2000 Standard Name: Spiral Seam Submerged Arc Welded Steel Pipe for Low-pressure Fluid Transmission Pipeline Standard Status:

Current English Title: Spiral Submerged Arc-Welded Steel Pipe for Pipelines for Low Pressure Field Fluid Service Alternatives: SY T 5037-1992 Date of Implementation:

2001-6-1 Promulgating Department:State Petroleum and Chemical Industry Administration Brief introduction:This standard stipulates the size, shape, weight, technical requirements, test methods, inspection rules, coatings, marks and quality certificates of spiral seam submerged arc welded steel pipes (hereinafter referred to as "steel pipes") for low-pressure fluid transmission pipelines.

This standard is applicable to steel pipes for ordinary low-pressure fluid transportation pipelines such as water, sewage, air, heating steam and flammable fluids, and also to steel pipes for other fluid transportation pipelines with similar requirements. Derivation.

5497 is the standard number, the number is the petroleum standard serial number given by the petroleum standardization management agency according to the petroleum standard plan, the initial is to give a set of numbers according to each specific period (usually year), and then the number is revised every four years, and each revision, the following year number is changed, and the standard number remains unchanged. It was not until the standard was invalidated that the number 5497 disappeared, and there were examples of reactivation abroad.

It has been replaced by PetroChina's enterprise standard Q SY1241-2009 "Safety Management Code for Hot Work", which is no longer an industry standard, but an enterprise standard.
