LSAW Pipe Mill
LSAW pipe mill, also known as JCOE steel pipe, it has one welding seam and uses the submerged arc welding process.
- LSAW Pipe Mill
LSAW pipe mill, also known as JCOE steel pipe, it has one welding seam and uses the submerged arc welding process. The specification range is from 325mm to 1420mm. When the diameter of the straight seam submerged arc welding pipe is greater than 914.4 mm, the standard stipulates that steel pipes is allowed to have two straight welding seams.
LSAW pipe complies with GB/T3091-2008 low pressure fluid steel pipe standard, GB/T9711 oil and gas pipeline standard, ASTM A252 welded structural steel pipe USA standard.
- Advantages
1. The production process is flexible, and the production efficiency is lower than that of HF ERW tube and Spiral welded steel pipe.
2. It can produce the pipe which is HF ERW tube mill, spiral pipe mill, even seamless steel pipe mill can not produce.
3. The production cost of LSAW pipe is higher than that of HF ERW tube and Spiral pipe, but there is a large discount space compared with seamless steel pipe.
4. It can produce the material and thickness which HF ERW tube mill and Spiral pipe mill can not produce.
5. It has been widely used in domestic heavy steel structure engineering and fluid pipeline engineering, foundation piling engineering.

Cooperation Process
We engage in in-depth requirement communication with clients to understand their specific needs, project scope, requirements, and expectations. During this stage, we establish effective communication channels to ensure mutual understanding of the project.
Based on the client's needs and requirements, we provide customized solutions and product design proposals. Our technical team offers professional advice and solution designs to ensure feasibility and optimization of the proposed solutions.
After confirming the solution design and product specifications, we negotiate cooperation terms with clients, discussing key terms such as cooperation mode, pricing, and delivery time in detail. Once mutual agreement is reached, we sign the formal contract, outlining rights and obligations of both parties.
We commence production according to the contract and design requirements. Throughout the production process, we strictly adhere to quality management systems, conducting comprehensive quality control and supervision to ensure products meet client requirements and standards.
Upon completion of production, we package, transport, and deliver the products to clients on time. We provide user manuals and technical support to ensure clients can use the products correctly.
We commit to providing comprehensive after-sales service and maintenance support, including technical support, training services, and maintenance. We aim to establish long-term and stable cooperation with clients, offering continuous support and service to ensure long-term stable operation of the products.
We value client feedback and opinions, regularly communicating with clients to understand their user experience and changing needs.
