Welded Fittings for Industrial, Oil & Gas, and LNG Pipelines
Product Overview
Our welded pipe fittings are engineered for the most demanding pipeline systems, including long-distance transmission, oilfield gathering, refinery process lines, and LNG cryogenic pipelines. Manufactured from carbon steel, stainless steel, or nickel-alloy steel, these fittings are designed to withstand:
- High pressure and high temperature for refinery process pipelines
- Corrosive media in chemical and oil/gas operations
- Cryogenic temperatures down to -162°C for LNG pipelines
These welded fittings ensure leak-proof, durable, and safe connections for industrial, oil & gas, and LNG pipelines worldwide. Compliant with ASTM, ASME, ISO, and API standards, they provide maximum reliability under extreme operating conditions.
Key Features
- Material Options: Carbon steel, stainless steel, nickel-alloy steels
- Design: Butt-welded or socket-welded ends for permanent, leak-proof connections
- Durability: High mechanical strength for high-pressure, high-temperature, and low-temperature service
- Corrosion Resistance: Suitable for aggressive and corrosive fluids
- Cryogenic Compatibility: For LNG pipelines at -162°C
- Standards: ASTM, ASME B31.3, ISO, API compliant
- Sizes: DN15–DN600 (custom sizes available)
- Applications: Long-distance pipelines, oilfield gathering, refinery process piping, LNG cryogenic lines
Product Types Description
- Elbows: 45°, 90°, and 180° welded elbows designed for smooth directional changes. Suitable for high-pressure refinery pipelines and LNG cryogenic pipelines.
- Tees: Equal and reducing tees for branching pipelines. Used in oilfield gathering systems and industrial process lines.
- Reducers: Concentric and eccentric reducers for safe diameter transitions in high-pressure, high-temperature, and cryogenic pipelines.
- Caps & Plugs: End closures for long-distance pipelines, refinery systems, and LNG storage pipelines.
- Flanges & Stub Ends: Ensure secure connections to valves, pumps, and equipment in industrial, oil & gas, and LNG pipelines.
Applications
Welded fittings are widely applied in:
- Long-Distance Pipelines – Oil, gas, and water transmission pipelines requiring high structural integrity and leak-proof connections.
- Oilfield Gathering Pipelines – Connecting wellheads, separators, and storage tanks, handling high pressure and corrosive fluids.
- Refinery Process Pipelines – High-pressure, high-temperature pipelines in chemical plants, oil refineries, and petrochemical facilities.
- LNG Cryogenic Pipelines – Pipelines for liquefied natural gas at -162°C, including storage, distribution, and transfer lines.
