Stainless Steel Socket Weld Fittings Manufacturer, Supplier & Exporter in India
Stainless Steel Socket Weld Fittings supplied by Astromet Steel & Engineering are precision-engineered fittings designed for small-diameter, high-pressure piping systems. In these fittings, the pipe is inserted into a recessed area of the fitting and welded around the joint, creating a strong and leak-proof connection.
Socket weld fittings are widely used where high structural integrity and vibration resistance are required. Stainless steel construction provides excellent corrosion resistance, strength, and durability, making these fittings suitable for aggressive environments and critical service conditions.
Astromet Steel & Engineering manufactures socket weld fittings using high-quality stainless steel with tight dimensional tolerances. Each fitting is thoroughly inspected to ensure compliance with international standards and customer specifications.
Our Stainless Steel Socket Weld Fittings offer long service life, easy installation, and reliable performance in demanding industrial applications.

Stainless Steel Socket weld Fittings Usage & Applications
Stainless Steel Socket Weld Fittings are commonly used in high-pressure and high-temperature systems where pipe sizes are small and leakage must be minimized. Typical applications include oil & gas processing lines, chemical and petrochemical plants, refineries, power generation units, hydraulic systems, and steam pipelines.
They are also preferred in instrumentation lines and process piping where strength, compact design, and vibration resistance are critical.
