LSAW Steel Pipe

LSAW steel pipe is a welded steel pipe produced using the straight seam submerged arc welding process. It is formed by bending a single steel plate into a tube shape, and then using submerged arc welding to weld the edges of the plates together.

We have LSAW steel pipes with complete specifications, and the welds have good toughness, strength, uniformity and density. At the same time, it has the advantages of large pipe diameter and thick pipe wall. Gnee has over 15 years of experience in the factory and can be sold at factory prices. Third-party steel pipe inspection services are supported, come and contact us to get a quote.

Gnee has a large inventory of LSAW steel tubes, which allows to meet customers’ needs and deliver products on time. This avoids delays in project progress due to shortages. Our inventory management system is highly precise, ensuring inventory accuracy and real-time updates. Whether it is mass production or individual customized needs, Gnee can provide quick responses, which brings convenience and confidence to customers.

LSAW pipes can be manufactured in large diameters, ranging from several inches to several feet. This makes them suitable for applications that require the transportation of large volumes of fluids or where a larger cross-sectional area is needed.

LSAW pipes are produced by using the submerged arc welding process, which ensures a high-quality and reliable weld joint. The welding method provides good weldability and produces a strong bond between the steel plates, resulting in a seamless appearance and excellent integrity.

LSAW pipes are versatile and can be used in various applications across different industries. They are suitable for both onshore and offshore projects, as well as for conveying different types of fluids such as oil, gas, water, and chemicals.

LSAW pipes have a longitudinal seam running along their length, which is formed during the welding process. This seam provides structural strength to the pipe and helps distribute loads evenly.

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.
