Benifit
The advantages of spiral welded pipes are as follows:
1. High strength: Spiral welding pipes have high strength, high stiffness, and can withstand high pressure.
2. Good welding performance: Spiral weld 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
As a large spiral welded pipe suppliers,Yuantai Derun 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.

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.
spiral welded pipe vs longitudinal
1、 Different production processes
The production process of straight seam welded pipe is relatively simple, and its processing method is to make steel pipes of a certain length after the steel plate undergoes processes such as opening, forming, welding, and straightening. Spiral pipes are made by rolling steel strips into a spiral shape and welding them by submerged arc welding. The production process is more complex than that of straight seam welded pipes.
2、 Differences in appearance
The appearance of straight seam welded pipes is square or rectangular, with clear and distinct welding lines. The spiral tube presents a spiral appearance, with relatively smooth welding lines that are not as obvious as straight seam welded pipes.
3、 Differences in performance
From a performance perspective, straight seam welded pipes are more stable and have less expansion and contraction compared to spiral pipes. However, spiral tubes are relatively unstable and prone to problems such as expansion and contraction. However, the production process of spiral pipes is more complex compared to straight seam welded pipes, and larger diameter pipes can be produced. Therefore, in some situations where large diameter steel pipes are required, traditional straight seam welded pipes are difficult to meet the requirements, while spiral pipes can be competent.
In general, both straight seam welded pipes and spiral pipes have their own advantages and disadvantages, and the specific use needs to be selected according to the specific situation and requirements.
