High Pressure SS Pipe Fittings 304 316 Stainless Steel Butt Weld Elbow

Classic austenitic stainless steel, with good oxidation resistance, atmospheric corrosion resistance and moderate acid and alkali resistance.

Cost-effective, stable performance, easy welding and processing.

Suitable for conventional high-pressure water, oil, gas, steam and general industrial pipelines.

Contains molybdenum(Mo) element, greatly enhanced resistance to pitting, salt water, chloride, acid and chemical corrosion.

High temperature resistance and creep strength are better than 304.

First choice for coastal areas, marine engineering, chemical, pharmaceutical, food processing and severe corrosive environments.

1. Seamless Integral Forming

   Adopt hot bending, cold forming and integral forging technology, no welding seam on the body, high overall density and strong compression resistance.

2. Precision Thickened Design

   Thickened wall thickness for high-pressure working conditions, strictly produced in accordance with high-pressure pipe schedule standards.

3. Solid Solution Heat Treatment

   Eliminate internal stress, improve toughness and welding performance, prevent deformation and cracking under long-term high pressure.

4. Fine Surface Treatment

   Smooth inner and outer wall, no burrs, no sand holes, reduce fluid resistance, prevent scaling and medium retention.

5. Strict Dimension Control

   End face bevel processing for standard butt welding, ensuring perfect matching with seamless steel pipes.

✅ Super High Pressure Resistance

Thickened structure and high-strength material, suitable for Sch40, Sch80 and extra heavy high-pressure working conditions, resistant to instantaneous pressure impact.

✅ Excellent High Temperature Resistance

Stable mechanical performance under high temperature environment, not easy to soften and deform, suitable for high-temperature steam and hot oil conveying.

✅ Strong Sealing & Firm Connection

Butt-weld full fusion connection, integrated with the pipeline, zero leakage, high safety for closed industrial circulation system.

✅ Outstanding Corrosion Resistance

Anti-rust, anti-oxidation, anti-acid and alkali, anti-salt spray, adapt to humid, coastal and chemical industrial environments.

✅ Smooth Fluid Conveyance

Smooth inner wall, small flow resistance, reduce energy consumption, not easy to block and accumulate dirt.
