This standard applies to wrought stainless steel pressure pipe fittings.
This standard includes many grades of austenitic stainless steel alloys. Based on the appropriate ASTM/ASME or MSS standards, grades are marked with a prefix. Many fitting classes are defined for each WP stainless grade, indicating whether seamless or welded construction was used. Classifications are also used to represent the nondestructive test technique and scope of nondestructive examination. A broad description of the fitting classes applicable to all WP grades of stainless steel follows. There are no classes for CR grades.
Fitting Standards for WP material 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. |
| 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. |
