Company Info

 

Finego Steel Co., Ltd utilizes advanced submerged arc welding equipment and technology to deliver high-quality submerged arc welded steel pipe products to customers. Our products boast excellent welding quality, high production efficiency, and wide applicability.

Attention to detail starts with the selection of raw materials. The raw materials for our submerged arc production line are directly sourced from large steel mills with whom we have established partnerships. The quality of the steel plates directly impacts the quality and performance of the pipes. Therefore, we prioritize raw material selection and tailor it to match the specific requirements of customer orders.

In addition to ensuring raw material quality and employing advanced submerged arc welding equipment, the production process emphasizes key steps such as steel plate pretreatment. This involves rust removal, degreasing, and edge grinding to ensure the cleanliness and smoothness of the steel plate surface. Core processes like "forming" and welding of the steel pipes are crucial, followed by heat treatment and air cooling. Welding technology is pivotal in the steel pipe manufacturing process, and we are constantly dedicated to improving our welding techniques.

After cooling, the pipes undergo inspection using online flaw detection equipment primarily to assess the quality of the weld seam for any defects. This meticulous process ensures the quality of the pipes. Subsequently, procedures such as sizing, straightening, and cutting to length are carried out, followed by visual, dimensional, and mechanical performance inspections of the finished pipes to ensure they meet customer requirements.

From raw material selection to final product inspection, we rigorously controls quality to ensure the provision of superior products and services to customers. We also offer comprehensive after-sales service to address any issues customers may encounter during the use of the pipes, safeguarding their interests.

No.101 Wanbo 1st Road, Nancun Town, Panyu District, Guangzhou, Guangdong, China In the multi-wire submerged arc welding of straight seam welded pipes, several key parameters significantly influence the welding process: welding current, arc voltage, and welding speed. Increasing the welding current of all wires results in higher reinforcement of the weld seam, with the first wire contributing the most to this effect. Arc voltage affects the width of the weld pool, with lower voltages causing narrower pools and potential issues with weld seam transitions. Controlling voltage is crucial to avoid undesirable weld pool shapes, such as the "gourd" shape. Welding speed impacts both the depth and width of fusion, with faster speeds leading to shallower and narrower welds. However, maintaining welding quality is paramount when adjusting speed to enhance production efficiency. Additionally, factors like power supply configuration, flux characteristics, and wire arrangement play essential roles in optimizing the welding process. Balancing these parameters ensures consistent weld quality, proper fusion, and efficient production in the fabrication of straight seam welded pipes through multi-wire submerged arc welding.

When we are in production, we adhere to balancing these parameters to ensure stable welding quality, correct fusion, and efficient production when manufacturing straight seam welded pipes through multi-wire submerged arc welding.

We have always regarded quality as our life and adhere to the principle of "quality first, customer foremost". We have established advanced physical and chemical laboratories capable of conducting various physical and chemical tests on steel pipes, ensuring that each pipe meets national and industry standards. If you need straight seam welded pipes, we will be your best choice.
