ASTM A403 Abstract
ASTM A403 WP316L covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations. All fittings shall undergo heat-treatment.
A403 WP316L equal tee is a pipe fitting made from 316L stainless steel and designed according to the standards set by ASTM A403, which is the specification for wrought austenitic stainless steel pipe fittings. The "WP" in the material specification refers to welded and pressure-rated pipe fittings, while "316L" is a low-carbon variant of 316 stainless steel, ideal for high-corrosion environments.
Fitting Classes for WP Grades
| CR | Corrosion resistant grade. S through WU Classes do not apply. |
| WP-S | Seamless |
| 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 |
| WP-WX | RT all welds with or without filler metal. |
| WP-WU | UT all welds with or without filler metal. |
| WP grade-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. |
