In the demanding world of oil and gas extraction, pipeline integrity is non-negotiable. Our Oil and gas sector welded stainless steel tube solutions are built to withstand the harshest downhole and surface conditions. We utilize advanced welding technologies to produce Stainless welded tubing for petroleum industry that meets the stringent demands of corrosion resistance and high-pressure tolerance. For long-distance transport, our Pipeline pipe for oil and gas transmission is engineered for consistent flow efficiency and minimal maintenance. Where extreme purity and strength are required, the Petroleum grade stainless welded conduit provides a secure pathway for critical control lines and chemical injection systems, ensuring uninterrupted operation.
The Oilfield Dedicated Welded Stainless Tube is produced from premium austenitic and duplex stainless steel grades, precisely formed and welded without filler metal to maintain a homogenous structure. Each tube undergoes eddy current testing or hydrostatic testing to guarantee zero leaks and perfect weld integrity. Below are the detailed technical specifications and standard dimensions that demonstrate our manufacturing precision.
| Nominal Size (OD x WT) | Working Pressure (bar) at 20°C | Typical Application |
|---|---|---|
| 1/4" × 0.035" (6.35 × 0.89 mm) | 690 | Hydraulic control lines |
| 3/8" × 0.049" (9.53 × 1.24 mm) | 620 | Chemical injection strings |
| 1/2" × 0.065" (12.7 × 1.65 mm) | 550 | Instrumentation & impulse lines |
| 1" × 0.083" (25.4 × 2.11 mm) | 400 | Subsea umbilical tubing |
| 2" × 0.109" (50.8 × 2.77 mm) | 320 | Process piping & heat exchangers |
| 4" × 0.237" (101.6 × 6.02 mm) | 250 | Flowline jumpers & spools |
The manufacturing process incorporates bright annealing in a pure hydrogen atmosphere to restore full corrosion resistance after welding. Advanced in-line dimensional monitoring ensures ovality stays within ±1% and wall thickness variation does not exceed ±10% of nominal. The Oilfield Dedicated Welded Stainless Tube is supplied with full material certification including chemical analysis, mechanical properties, and pressure test reports, enabling rapid deployment in critical oilfield services from well completion to refinery operations.
