What Services Does Gnee Provide?

Gnee can provide the following measurement services for carbon steel pipe:

1. Dimensional measurement: Measure the dimensional parameters such as length, width, and thickness by measuring instruments to ensure the pipe is qualified and meets the design requirements.
2. Surface measurement: Measure parameters such as flatness, unevenness, and surface roughness of the pipe surface to help ensure that the quality and surface state of the pipe meet the requirements.
3. Thickness measurement: Use a thickness measuring instrument to accurately measure the thickness of the carbon steel pipe to ensure that it meets the design requirements.
4. Material measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the product to ensure that the quality and performance meet the requirements.
5. Bending and Deformation Measurements:The degree of bending and deformation of the steel pipe is measured and monitored by using tools such as bending measuring instruments and displacement sensors to ensure that it is within the allowable range.

Purchasing Gnee carbon steel pipe can provide the following deep processing services. We can customize according to the specific needs of customers to meet the requirements.

Cutting service: Carbon steel pipe can be custom cut to obtain the desired shape and size according to the needs of customers. For example, flame cutting, plasma cutting, laser cutting, etc., can cut steel pipes into required blocks, special-shaped parts.
Bending and forming: Carbon steel pipes are bent and formed by stress application and appropriate processes to obtain the desired shape.
Welding service: Carbon steel 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 carbon steel 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 carbon steel pipe can provide the following testing services through third-party testing agencies. These third-party testing services can provide independent, objective verification that carbon 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 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 carbon steel pipes to evaluate their quality and performance.
Corrosion performance test: Through the corrosion performance test, evaluate the corrosion resistance of carbon steel 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.
