What‘s The Feature Of Gnee Welded Steel Pipe?

Welded steel pipe

Welded steel pipes are made from high-quality steel, providing excellent strength and durability. They are capable of withstanding high pressure and heavy loads, making them suitable for applications requiring robust piping.

Welded steel pipes come in a wide range of sizes, diameters, and thicknesses, offering versatility for different applications. They can be used in industries such as oil and gas, construction, water supply, plumbing, structural support, and more.

The welding process used in the production of welded steel pipes ensures strong and reliable weld joints. Common welding methods include electric resistance welding (ERW), submerged arc welding (SAW), and high-frequency induction welding (HFIW). These welding techniques provide secure connections and consistent quality.

Welded steel pipes have a broad range of applications. They are commonly used for fluid transportation (water, oil, gas), structural support in construction, piling, fencing, HVAC systems, and more. They can be used for both underground and aboveground installations.

Welded steel pipes undergo stringent quality control measures during the manufacturing process to ensure they meet industry standards and specifications. This ensures reliability and long-term performance, minimizing the risk of leaks, failures, or structural problems.

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.
