A420 WPL6 Low Temperature Butt Weld Fittings 45 Degree Elbow Refrigeration

A420 WPL6 low temperature butt weld fittings are engineered for pipelines operating below the ductile-to-brittle transition temperature of standard carbon steel. This 45-degree elbow is manufactured from ASTM A420 WPL6 killed steel and undergoes impact testing at -46°C, ensuring exceptional toughness and safety in refrigeration and cryogenic applications.

Low temperature carbon steel fittings prevent brittle fracture that can occur when conventional carbon steel is exposed to cold temperatures. This elbow is normalized and impact tested, making it ideal for cold storage facilities, refrigeration systems, LNG auxiliary lines, and cold process piping.

Every A420 WPL6 elbow is manufactured to ASME B16.9 and ASTM A420 dimensional standards, with carefully controlled carbon, manganese, silicon, and phosphorus chemistry to ensure low temperature toughness. Each heat lot is impact tested and accompanied by complete material certification.

The 45-degree angle provides a gradual directional change that maintains smooth refrigerant flow while minimizing vibration. For cold service applications requiring certified low temperature butt weld fittings, this elbow delivers reliable performance and straightforward field welding.

Every low temperature butt weld fitting is packaged in seaworthy wooden cases or pallets with protective end caps. We offer customized marking and labeling services, and can consolidate mixed sizes in single shipments to optimize freight costs and handling efficiency.

As a manufacturer of low temperature butt weld fittings, we support custom sizes, wall thicknesses, and materials, and can arrange third-party inspections through SGS, BV, or TUV upon request. Our engineering team reviews every inquiry to recommend materials, wall thicknesses, and standards that best match your pressure, temperature, and corrosion requirements.

Each low temperature butt weld fitting order undergoes dimensional inspection against applicable standards before dispatch, and our quality team maintains sample records available for re-testing upon request. We welcome factory audits and pre-shipment inspections from international buyers and can provide reference projects and test reports to support your tender documentation.
