What are alloy steel A234 WP9 pipe fittings?

The process of manufacturing the ASTM specified A234 WP9 pipe fittings is referred to as wrought. Wrought grade fittings mean the alloy has been either cast or forged. The material used to produce ASTM A234 WP9 is low content alloy steel. One of the features of this low alloy steel grades is that the fittings have the ability to exhibit a good performance between moderate to high temperature conditions. The ASTM A234 WP9 Fittings can be segregated into two classes, Class 1 and Class 3, both of which have different mechanical properties. Class 3 fittings e.g. the ASTM A234 WP9 Tee tends to have a much better yield strength and tensile strength. Since these alloy steel based ASTM A234 Gr WP9 Elbow is able to function well in elevated conditions, these fittings are widely used across several industrial areas such as Oil, Gas, Power plant, Water Treatment as well as the Chemical processing industry.

What makes the alloy steel WP9 pipe fittings a good investment in these fields is their method of forming as well as its after procedure which includes cooling to a temperature that is below the critical range. And the rate of cooling must be similar to that of air cooling. Although the forging process used on the ASTM A234 Grade WP9 pipe fittings must be performed in a manner that does not cause defects on the fittings, manufacturers can weed out the less than perfect fittings by performing a set of tests on them. Generally, tests such as tension test, hardness test, as well as a hydrostatic test are carried out on the samples of these fittings.
