The material and use of straight seam steel pipe

General Low-Pressure Fluid Transport Pipes:

Description: These straight seam steel pipes are primarily used for transporting general low-pressure fluids such as water, gas, air, oil, and heating steam.

Specifications: The pipe ends can be non-threaded or threaded, and their nominal diameter is usually measured in inches, which approximates the inner diameter.

Uses: Directly for fluid transport and as the base pipeline for galvanized welded steel pipes used in low-pressure fluid transportation.

Ordinary Carbon Steel Wire Casing:

Description: A type of straight seam steel pipe used to protect wires.

Applications: Employed in industrial and civil buildings, machinery and equipment installations, and other electrical installation projects.

Metric Electric Welded Straight Seam Steel Pipes:

Description: These pipes have seams parallel to the length direction and include variants like electric welded thin-walled pipes and transformer cooling oil pipes.

Spiral Seam Submerged Arc Welding Pressure Fluid Transport Pipes:

Description: Made from hot-rolled strip steel, these spiral welded pipes are formed at specific temperatures and welded with double-sided submerged arc welding.

Features: High pressure-bearing capacity, good welding performance, safe, reliable, and efficient for transport.

Applications: Mainly used for oil and natural gas pipeline transportation, offering large diameter and high transportation efficiency, which reduces investment in pipeline infrastructure.

Spiral Weld High-Frequency Welded Steel Pipes for Pressure Fluid Transport:

Description: These pipes are made from hot-rolled strip steel coils using high-frequency lap welding.

Features: Strong pressure-bearing capacity, good plasticity, convenient welding, and efficient for fluid transport.

Applications: Primarily used for oil and natural gas transportation, providing safety, reliability, and cost-efficiency in pipeline infrastructure.

Hot-Rolled Steel Strip Coil Pipes:

Description: Pipes formed from hot-rolled steel strip coils, typically welded using double-sided automatic submerged arc welding or single-sided welding.

Spiral Welded High-Frequency Welded Steel Pipes for Low-Pressure Fluid Transport:

Description: Formed from hot-rolled strip steel at specific temperatures, these spiral welded pipes are used for transporting low-pressure fluids.

Spiral Welded Steel Pipes for Piles:

Description: Made from hot-rolled steel strips, formed by double-sided submerged arc welding or high-frequency welding.

Applications: Suitable for foundation piles in civil structures, docks, and bridges.

Advantages: Simple production process, high efficiency, low cost, and rapid development. They can produce larger diameter pipes with narrower billets and different diameters with the same billet width, improving productivity despite a 30%-100% increase in weld length compared to straight seam joints.
