For spiral steel pipes used in rainwater pipelines, anti-corrosion treatment is crucial. The company can also produce single-layer and double-layer fusion bonded epoxy powder (FBE), double-layer polyethylene (2PE), three-layer polyethylene (3PE), double-layer polypropylene (2PP), three-layer polypropylene (3PP), epoxy coal tar anti-corrosion coating and other external anti-corrosion projects for steel pipelines, as well as pipeline anti-corrosion projects with various internal coating structures such as IPN8710 high molecular weight anti-corrosion coating and cement mortar pipeline inner wall anti-corrosion, in accordance with standards such as DIN30670, DIN30671, SY/T4013-2002, SY/T0315-97.

The water supply system pipeline is a type of pipeline product manufactured by spiral winding, using strip steel coils as raw materials, often formed by warm extrusion, and welded into spiral seams using automatic double wire double-sided submerged arc welding technology. It has the characteristics of high strength, corrosion resistance, and high pressure resistance, and is currently an important choice in the construction of water supply pipelines.

Spiral steel pipes for infrastructure pipelines, also known as spiral pipes or spiral welded pipes, are industrial steel pipes made by rolling steel strips into billets at a certain helix angle (forming angle), and then welding the pipe seams together. Their specifications are expressed as outer diameter * wall thickness. There are two types of welding: single-sided welding and double-sided welding. The pipe body must ensure that the hydrostatic test, tensile strength, and cold bending performance of the weld meet the requirements.

Spiral steel pipe is a type of pipeline used for transporting high-temperature hot water, usually manufactured using spiral welding technology. It is widely used in residential heating, hot water and steam transportation, oil and gas pipelines and other fields. It is often seen in urban centralized heating pipelines, oil transportation pipelines, water transmission pipelines in high-altitude areas, and industrial pipeline projects in production areas.

The urban water supply system is a key part of urban infrastructure, and spiral steel pipes, as an ideal pipeline material, are widely used in the construction of urban drinking water pipelines. It can meet various requirements of pipeline materials for urban water supply systems, and with the acceleration of urbanization, its application will be more extensive.

Spiral steel pipes for gathering and transportation pipelines have become the preferred material for long-distance transportation in oil and gas, chemical, and municipal engineering due to their unique structure and performance advantages. The following are its core points:
