S235 Steel Pipe

S235 steel pipe refers to a type of structural steel pipe that is manufactured according to the EN 10219 standard. The “S” in S235 stands for structural steel, and the number indicates the minimum yield strength of the steel (in this case, 235 MPa).
Gnee offers a wide selection of steel pipe size ranges that can be customized to your specific requirements. We have advanced processing equipment and technical teams to perform cutting, welding, drilling, and other processing of steel pipes according to your requirements. Our factory advantages and preferential prices will ensure that you get satisfactory products and services. choose us!

S235 steel pipe has a good combination of strength and durability, making it suitable for structural applications. The steel pipe has excellent weldability and can be easily and efficiently joined during fabrication or installation. S235 steel pipes can be easily manipulated and used in various forms such as round, square or rectangular shapes to suit different structural requirements.
S235 steel pipes are widely used in construction, mechanical and structural engineering fields.

What Services Does Gnee Provide?

Gnee can provide the following measurement services for 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 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 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.

Ask Measurement service

Gnee can customize the size and shape of steel pipes for your project according to specific project needs. The custom design of the pipe is carried out by a professional engineer and design team. Based on the requirements and constraints of the project, they will use calculation and simulation tools, combined with experience and technical knowledge, to optimize the steel pipe design to meet the specific needs of your engineering.

● According to the strength requirements of structural design, adjust the thickness, width, and length of pipes.
● The shape of the steel pipe can be designed according to the characteristics of the project.
● If you consider the convenience of installation and maintenance, we can also add openings and passages for easy access and operation in the design for areas that require frequent maintenance.

Ask Customized Services

Purchasing Gnee 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: 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: Pipes are bent and formed by stress application and appropriate processes to obtain the desired shape.
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.

Ask Deep Processing Services

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.
