Product Description

Product Description

SSAW STEEL PIPE

The SSAW (Spiral Submerged Arc Welded) Steel Pipe represents a marvel of modern engineering, crafted through an intricate process of spiral welding. This double-sided submerged arc welding technique transforms narrow sheets or hot-rolled coils into expansive, large-diameter pipes at an optimized cost. Designed for extensive oil and gas transportation, the spiral welding method ensures robust, reliable pipes that deliver exceptional performance.

Process
Carbon Steel Seamless Pipe Uses - In the Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, the welding line takes on a distinctive helix shape. Utilizing the same advanced Submerged Arc Welding technology as LSAW pipes, the primary distinction lies in the spiral versus longitudinal welding approach. This process involves rolling steel strips at an angle to the pipe center, which results in a seamless, spiral welding seam, perfectly engineered for strength and durability.

Application
Our SSAW Steel Pipes are versatile, excelling in various sectors: Oil and Gas Pipelines for efficient energy transport, Water Transmission systems, Liquid Transportation, robust Building and Steel Structure Construction, Offshore and Onshore Construction, Piling Works, Electricity, and Heating Power infrastructure, among others.

ADVANTAGES OF SSAW STEEL PIPE

(1) Our innovative use of uniform-width steel strips allows for the versatile production of pipes across various diameters, notably facilitating the creation of large-diameter pipes from narrow strips.

ADVANTAGES OF SSAW STEEL PIPE

(2) Under similar pressure conditions, spiral welded pipes endure 75% to 90% less stress compared to straight seam variants, enabling them to withstand higher pressures. This efficiency allows for a thinner wall construction by 10% to 25% compared to equivalent straight welded pipes of the same outer diameter.

ADVANTAGES OF SSAW STEEL PIPE

(3) Precision is paramount, with diameter tolerances maintained below 0.12%, deflection under 1/2000, and ellipticity less than 1%, eliminating the need for additional sizing and straightening processes.

(4) This method supports continuous production, theoretically yielding infinitely long pipes, while minimizing cutting waste to enhance metal utilization by an impressive 6% to 8%.

ADVANTAGES OF SSAW STEEL PIPE

(5) Its flexible operation and convenient type adjustments elevate the SSAW pipe's production efficiency and adaptability.

(6) Lightweight equipment with minimal initial investment requirements allows for creating mobile trailer-type flow units, enabling on-site pipe production where pipeline installation occurs.

(7) Easily integrates with mechanized and automated production systems, maximizing productivity and consistency.
