ASTM A234 WPB is a standard specification for carbon steel buttweld fittings. It covers seamless and welded fittings made from wrought carbon steel, commonly used in high-pressure and high-temperature applications.
An elbow is a standard fitting with a fixed radius (like 1.5D or 3D), while a bend is a more flexible term referring to any curved section of pipe, often custom-made with longer radii (e.g., 5D).
Yes, we manufacture non-standard and custom-designed flanges according to customer specifications, including ANSI, JIS, BS, DIN, and AS standards.
We use carbon steel, alloy steel, and stainless steel, compliant with international standards such as ASTM, GB, DIN, ANSI, and JIS.
