ASTM A234 WP91 Pipe Fittings are weldable pipe fittings that are applied with pressure pipe systems at elevated temperatures and the material grad is denoted by the number 91. There are different material grades in the same standard and they all have different mechanical properties. Naveen Industries is a large supplier of the fittings in this grade. Our ASTM A234 WP91 pipe fittings are used in applications that require high temperatures and high pressures such as the hydraulic systems, underwater pipes, petroleum refineries, oil and gas industries and applications in the food processing an power generation plants.

We supply the ASME SA234 WP91 pipe fittings in different types and sizes. There are tees, elbows, bends, reducers and crosses in the WP 91 alloy steel fittings. Each of them have unique functionalities. The WP91 elbow is used to turn the pipe direction. The elbows are usually at 45 degree, 90 degree or 180 degrees of angle. The WP91 reducer on the other hand reduces the diameter of the pipe. There are two types, the concentric and eccentric types. The WP 22 tee is a tri-junction of pipes that can come with different sizes or the same size to fit in various sizes of pipes. Our WP22 fittings are manufactured with high standards and you can contact us for any inquiries.
