Detail Information
Spiral Welded Pipe
Spiral welded pipe is one kind of welded steel pipe,It is a welded circular hollow section made using SSAW steel pipe forming process. The advantages are large caliber and good rigidity. Spiral welded pipes are commonly used in various scenarios of fluid transportation.Yuantai Derun is a large china spiral welded carbon steel pipe factory.

The advantages of spiral welded steel pipes are as follows:
1. High strength: Spiral welded steel pipes have high strength, high stiffness, and can withstand high pressure.
2. Good welding performance: Spiral welded steel pipes have good welding performance and can achieve efficient and high-quality welding.
3. Large size range: Spiral welded steel pipes have a large size range, which can meet the needs of various engineering fields.
4. Corrosion resistance: After coating protection, spiral welded steel pipes have excellent corrosion resistance and can resist the erosion of various corrosive media.
5. Environmental protection and energy conservation: Spiral welded steel pipes have the characteristics of environmental protection and energy conservation in the production and use process.
Coating
Spiral welded pipe in accordance with the application of different anti-corrosion needs, spiral welded pipe also needs different coating treatment. Common spiral welded pipe coating treatment are the following: TPEP coating anti-corrosion, 3PE coating anti-corrosion, epoxy resin coating anti-corrosion, cement mortar coating anti-corrosion, epoxy coal asphalt coating anti-corrosion, IPN8710 coating anti-corrosion and so on.
TPEP Anti Corrosion Spiral Steel Pipe
TPEP anti-corrosion spiral steel pipe is a composite steel pipe with external anti-corrosion using 3PE and internal anti-corrosion using epoxy powder.
3PE Anti-Corrosion Spiral Steel Pipe
3pe anti-corrosion spiral steel pipe structure
One layer of epoxy powder (FBE>100um)
Second layer adhesive (AD) 170-250um
The third layer of polyethylene (PE) is 2.5-3.7mm.
Epoxy Resin Anti-Corrosion Spiral Steel Pipe
Good durability, the cured epoxy resin film is tough, water-resistant, non-toxic, and non polluting to water. Strong adhesion, with good adhesion between paint films.
Cement Mortar Anti-Corrosion Spiral Steel Pipe
Cement mortar anti-corrosion steel pipe can absorb a lot of heat energy because the steel pipe is filled with concrete, and the raw material is mainly a mixture of cement, sand and water, which is often called cement mortar.
Epoxy Coal Asphalt Anti-Corrosion Spiral Steel Pipe
The components of epoxy coal tar anti-corrosion steel pipes are epoxy coal tar primer and topcoat, both of which are mainly composed of epoxy resin and coal tar as film-forming materials, and are made by adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc.
Ipn8710 Non-Toxic Drinking Water Inner Wall Anti-Corrosion Spiral Steel Pipe
The IPN8710 non-toxic drinking water inner wall anticorrosive steel pipe is used to transport water. The water is not very corrosive, but it can react with iron to form black rust. If there is a leak in the system, oxygen can cause red rust (iron trioxide-based) to form. This affects water quality. We use IPN8710 non-toxic drinking water inner wall anti-corrosion steel pipe to solve this problem.
Spiral Welded Pipe Manufacturing Process
Yuantai Derun adopts the typical china spiral welded steel pipe manufacturing process for more efficient production and better product quality. The following are the main steps of the spiral welded pipe manufacturing process.
uncoiling->straightening->trim->internal welding->external welding->plasma cutting->x ray testing->repair welding->hydrostatic test->Spray marking into the warehouse

Application
Spiral welded steel pipe is used for many industries. Such as:
Spiral pipe for drainage: used in waterworks, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, as liquid or gas transportation.
Spiral pipe for dredging: used in dredging projects with strict production standards and quality assurance.
Piling Spiral Pipe: used in civil engineering structures, wharves, bridges and other foundation piles, with a large range of specifications and strict manufacturing standards.
Oil and gas spiral pipe: mainly used for oil and gas transportation.
FAQ
what is spiral welded pipe?
People call the steel pipe made by double-sided spiral welding process spiral welded pipe.
What is the formula for calculating the theoretical weight per meter of spiral welded pipe?
Theoretical weight per meter of spiral welded pipe calculation formula:
W = 0.0246615 (D-S) S + 0.5
In the formula:
W - spiral welded pipe theoretical weight per meter, kg/m;
D - spiral welded pipe nominal outside diameter, mm;
S - spiral welded pipe nominal wall thickness, mm.
How to Know the weight of spiral welded pipe?
The actual weight of a spiral welded pipe is obtained by weighing it in pounds. It should be noted that the actual weight and the theoretical weight are sometimes not the same.
What is disadvantages of spiral welded pipe？
The disadvantage of spiral welded pipe is that the weld seam is long, requiring a lot of filler work and low productivity.
What is american spiralweld pipe ?
American Spiralweld Pipe is steel pipe made by rolling a flat sheet of steel into a spiral shape and welding the edges together. This makes strong, durable pipes. They are used in water and sewage systems, oil and gas pipelines, and structural projects. The spiral design makes the pipes resistant to pressure and environmental factors.
