Welded steel pipe for gas and oil lines refers to carbon steel piping systems manufactured by forming steel plates and sealing the seams using high-frequency induction (ERW) or submerged arc welding (LSAW/SSAW). Predominantly governed by the API 5L (ISO 3183) standard, these pipes are engineered to transport hydrocarbons under high pressure, balancing cost-efficiency with extreme […]
Choosing the right welding method is critical for pipeline safety and project budget. The industry primarily relies on three types: ERW (Electric Resistance Welded): Created through cold-forming. Best for smaller diameters and medium-pressure distribution lines. LSAW (Longitudinal Submerged Arc Welded): Features a single longitudinal seam. Ideal for heavy-wall, large-diameter, and high-pressure long-distance pipelines. SSAW (Spiral […]
