Welding service: Pipe can be subjected to various types of welding services, including manual arc welding, gas-shielded welding, laser welding, etc.
Turning and machining of holes: Turning and machining of holes in pipes by using machining equipment. These processes produce smooth surfaces, precise holes and threads to meet specific assembly requirements.
Surface treatment: In order to improve the corrosion resistance and aesthetics of the steel pipe, surface treatment can be carried out. This includes methods such as spraying, hot-dip galvanizing, electroplating, etc. to add a protective layer and provide corrosion resistance.
Gnee can provide the following testing services through third-party testing agencies. These third-party testing services can provide independent, objective verification that pipes comply with relevant standards and regulations.
Material chemical composition analysis: Through chemical composition analysis, determine whether the composition of the steel pipe meets the standard requirements.
Mechanical performance test: Mechanical performance test includes tensile test, impact test, bending test, etc., which are used to determine whether the mechanical properties such as strength, toughness and ductility of products meet the specified requirements.
Metallographic testing: Through metallographic testing, check the structure, grain size, non-metallic inclusions, etc. of pipes to evaluate their quality and performance.
Corrosion performance test: Through the corrosion performance test, evaluate the corrosion resistance of pipes, including salt spray corrosion resistance, chemical corrosion resistance, etc.
Hardness test: Hardness test is used to measure the hardness of pipe, and its strength and wear resistance can be evaluated according to the hardness value.
Ultrasonic flaw detection: Ultrasonic flaw detection is used to detect internal defects of pipes, such as cracks, pores, inclusions, etc.
