SSAW Pipe Suppliers in China| SSAW Steel Pipe Selection

SSAW steel pipes are a critical type of pipe used in oil and gas extraction and transportation. In addition to SSAW pipes, there are also ERW pipes and SMLS pipes; pipes produced using these two manufacturing processes are primarily designed for short-distance transportation or high-pressure, high-temperature environments. Therefore, for large-scale transportation projects, SSAW (spiral submerged arc welded) […]
LSAW Steel Pipe Supplier in US- LSAW Pipe Manufacturer

Globally, LSAW (Longitudinal Submerged Arc Welded) steel pipes are widely used in various high-demand industrial projects due to their large diameter, thick wall, high pressure resistance, and strong low-temperature corrosion resistance. LSAW welds offer excellent toughness, plasticity, uniformity, and density. According to API standards, when passing through Class 1 and Class 2 areas such as […]
