Stainless steel pipe fittings manufacturer

Get the best quality ASTM A403 SS buttweld fittings from creative piping at low price

Stainless steel fittings stand as essential components in piping systems, seamlessly interconnecting pipes to ensure the fluid flow across diverse industries. Comprising a composition blending iron, chromium, nickel, and other alloys, these fittings exhibit exceptional corrosion resistance and durability, meeting critical requirements in petrochemical, pharmaceutical, and food processing sectors.

Manufacturing techniques such as investment casting and forging shape these fittings. Investment casting creates intricate shapes by pouring molten stainless steel into molds, while forged fittings gain strength through compressive force, making them ideal for high-pressure and high-temperature applications. Adherence to industry standards is paramount, with ASTM A403 specifying requirements for wrought austenitic stainless steel fittings, encompassing dimensions, tolerances, and material properties.

Crucial in maintaining piping system integrity, particularly in corrosive environments, stainless steel fittings demonstrate versatility across industries, meeting demands for durability, reliability, and resistance to harsh substances. In essence, these fittings embody metallurgical precision and adaptability to diverse industrial needs.

Our Stainless steel reducer and ss equal/ unequal tee are available in various thickness and sizes to suit different applications for oil and gas industries

Stainless steel fittings WP grades

WP-W	Welded, RT or UT all pipe starting material welds made with filler metal. All fitting manufacturer welds except as excluded in A/SA403 paragraph 5.4.3. If UT is substituted for RT, all welds must be examined 100% for their length as required by A/SA403 paragraph 5.6
CR	Corrosion resistant grade. S through WU Classes do not apply.
WP-S	Seamless
WP-WX	RT all welds with or without filler metal.
WP-WU	UT all welds with or without filler metal.
WPgrade-grade-class	Insert grades (304-304L) and class (S,W,WX, or WU). Applies to fittings meeting all chemical and physical requirements of both grades.
