What Is Spiral Welded Steel Pipe
SSAW steel pipes(spiral welded steel pipe) are produced through a welding process where the steel coil is spirally formed into a tubular shape and welded internally and externally using a submerged arc welding process. This method ensures a strong and continuous seam, making the pipe robust and reliable.
SSAW steel pipe has the following characteristics:
High Strength: The spiral welding process provides high strength and resistance to pressure.
Flexibility in Sizes: SSAW pipes can be produced in a wide range of diameters and wall thicknesses.
Cost-Effective: The production process is efficient, resulting in a cost-effective solution for many applications.
Resistance to Corrosion: With appropriate coatings and treatments, SSAW pipes can offer good resistance to corrosion.
SSAW steel pipes are a popular choice in many industries due to their combination of strength, flexibility, and cost-effectiveness. Their unique manufacturing process allows for a high degree of customization, making them suitable for a variety of applications.Mainly used for:oil and gas transportation, water supply systems, construction, infrastructure,etc.

Finish of SSAW Spiral Welded Steel Pipe
3PE & FBE Coating:
The 3PE coating consists of three layers:
Epoxy Primer: The innermost layer provides excellent adhesion to the steel pipe and resists corrosion.
Adhesive Layer: This middle layer binds the epoxy primer to the outer polyethylene layer.
Polyethylene Layer: The outermost layer offers mechanical protection against physical damage and additional corrosion resistance.
3PE SSAW spiral steel pipes are a reliable and efficient choice for many industrial applications due to their excellent corrosion resistance, durability, and cost-effectiveness. Their unique construction and protective coating make them ideal for transporting fluids and gases in demanding environments.
On the other hand, FBE is a two-layer coating system consisting of a particle filled epoxy resin substrate and a polyamide topcoat. Particle filled epoxy resin has excellent adhesion to metal surfaces, while topcoats have excellent chemical resistance and wear resistance. Fusion bonded epoxy resin coatings are used in various applications, from oil and gas pipelines to water and wastewater systems.

Galvanized Coating：
This type of SSAW spiral steel pipe is coated with a layer of zinc through a galvanizing process. This zinc coating provides a protective barrier against corrosion, preventing the steel from rusting.
Advantages:
Corrosion Resistance: The zinc coating from galvanization offers excellent protection against corrosion, significantly extending the pipe's lifespan, especially in outdoor and harsh environments.
Durability: The SSAW process results in a strong, high-quality weld seam, while the galvanization adds an extra layer of protection, enhancing the overall durability of the pipe.
Cost-Effectiveness: The spiral welding process is efficient and economical for producing large-diameter pipes, and galvanization is a cost-effective method for protecting the steel.
Maintenance-Free: The galvanized coating requires minimal maintenance, reducing the need for frequent repairs or replacements.
Versatility: These pipes can be used in various applications, including construction, water supply, and other industrial purposes.
Galvanized SSAW spiral steel pipe are an excellent choice for various industrial and construction applications due to their superior corrosion resistance, strength, and cost-effectiveness. The combination of spiral welding and galvanization ensures a durable, long-lasting pipe that performs well in demanding environments.
