Brief: Join us for a close-up look at this solution and see it in action. In this video, we demonstrate the manufacturing and quality control processes for 304 Stainless Steel Elbow Fittings, including beveled end preparation for superior welding, surface treatment for corrosion resistance, and packaging standards for international export. You'll learn how these 90-degree elbows meet strict dimensional and material specifications for industrial and sanitary applications.
Related Product Features:
  • Available in a wide range of sizes from 1/2" to 72" (DN15 to DN1800) to suit various industrial piping systems.
  • Constructed from high-quality 304 stainless steel, ensuring excellent corrosion resistance and mechanical properties.
  • Features precisely beveled ends with controlled angles and edges to facilitate high-quality welding and strong joint integrity.
  • Surface treated via shot peening to remove iron oxide and coated with anti-corrosive paint for enhanced durability and export readiness.
  • Manufactured to meet international standards including ASME, ANSI B16.9, DIN, JIS, and EN for guaranteed performance and compatibility.
  • Suitable for multiple applications in petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, and water/nuclear power industries.
  • Offered in various pressure ratings from Sch5 to Sch160 and XXS, accommodating different system requirements.
  • Available in both Long Radius (LR) and Short Radius (SR) configurations with angles including 30, 45, 60, 90, and 180 degrees.
Faqs:
  • What materials are these stainless steel elbow fittings available in?
    These fittings are primarily made from 304 stainless steel, but are also available in other grades including 304L, 316, 316L, 321, and various carbon steel and alloy steel options according to ASTM, DIN, JIS, and GB standards to match your specific piping requirements.
  • How are the elbow fittings prepared for welding applications?
    To ensure optimal welding quality, the end parts of these fittings are precisely beveled with controlled angles and edge thicknesses. This preparation, along with matching the steel grade to your piping system, guarantees strong, reliable welded joints in industrial installations.
  • What packaging and surface treatment is provided for export purposes?
    For export readiness, all fittings undergo surface treatment where iron oxide is removed via shot peening, followed by application of anti-corrosive paint. Small fittings are packed in wooden cases up to 1 cubic meter, while larger pieces (24" and above) are individually packaged, with clear marking of size, steel grade, batch number, and manufacturer trademark.
  • What standards do these industrial elbow fittings comply with?
    Our elbow fittings are manufactured to meet multiple international standards including ASME, ANSI B16.9, DIN 2605-2617, JIS B2311-2313, and EN 10253-1/2, ensuring they are suitable for global industrial applications and compatible with various piping systems.
