You can rest assured to buy Pengfa Spiral Welded Pipe Pile from our factory and we will offer you the best after-sale service and timely delivery. In the manufacturing process of spiral steel pipe, there are two ways: longitudinal welding and circumferential welding, among which circumferential welding is the most critical step. Circumferential welding requires the use of an automated welding system that points the welding torch toward the outer surface of the steel plate, making the welding more beautiful. At the same time, parameters such as welding speed, welding current and voltage should be controlled for circumferential welding to ensure that environmental factors such as temperature and humidity in the welding process match the welding process.

The production of spiral steel pipe requires steel plate crimping. The traditional steel plate crimping is crimped back and forth between two plate rollers. The surface of the steel pipe produced in this way is uneven, and there are great quality problems. In order to solve this problem, the production of steel pipe usually uses three - roll curved bending machine to roll steel plate. This machine has the advantages of fast coil speed, small bending radius and high quality of finished products, which greatly improves the manufacturing efficiency of spiral steel pipe.

Spiral steel pipe is a kind of pipeline material used for conveying oil, natural gas, water and other fluids. It has the characteristics of high strength, corrosion resistance and strong compression ability. Its advanced technology, products are widely used, can effectively protect the pipeline, prolong the service life of the pipeline, is a kind of pipeline material worth promotion and application.
You can rest assured to buy Pengfa Q235B Spiral Welded Pipe from our factory and we will offer you the best after-sale service and timely delivery. Spiral steel pipe is made of steel pipe with certain wall thickness by rolling strip steel through multiple processes, and then the steel pipe is put into water for epoxy coal asphalt anticorrosion. This technology can effectively improve the corrosion resistance of steel pipe and prolong the service life of steel pipe. Secondly, the product use of spiral steel pipe. Spiral steel pipe is mainly used in petrochemical industry, natural gas transmission, water conservancy engineering and other fields. In the field of petrochemical industry, spiral steel pipe can play the role of heat preservation, anticorrosion, moisture-proof and so on, effectively protect the service life of equipment; In the field of natural gas transportation, spiral steel pipe can effectively transport natural gas and improve transportation efficiency; In the field of water conservancy engineering, spiral steel pipe can play a role in protecting water source and preventing water pollution.

Choosing spiral steel pipe as sewage pipe material can solve urban drainage problems, improve the quality of life and production efficiency, but also make due contribution to environmental protection.
You can rest assured to buy Pengfa Spiral Steel Tubes for Petroleum and Natural Gas from our factory and we will offer you the best after-sale service and timely delivery. Spiral steel pipe has the advantages of large diameter, light weight and good compressive performance, and is often used in pipeline engineering. Today, we use it for sewage pipes. With the acceleration of urbanization, urban sewage is increasing day by day. Traditional drainage pipes usually use cement pipe or plastic pipe as the main material, but these materials have a limited service life, often need to be replaced frequently, at the same time, there is a strong odor and stink, to people's living environment has a great negative impact.
