Information

Cr-Mo WP91 pipe elboware the elbows that are effectively utilized at the pressure piping system at average to high-temperature services. The standard specification of this material is ASTM A234. It is indicating the material properties of various kinds of alloy steel and carbon steel (CS). WP91 material is the commonly used steel grade in which W stands for weldable, P stands for pressure and 91 is the grade. The regular items of A234 WP91 Fittings are cross, elbows, caps, tees, cross, and reducers, etc.

Our offered ranges of Alloy Steel WP91 Pipe elbows are having several features to offer. It is like-
• High hardiness
• Rugged construction
• Pitting and oxidation resistant
• Dimensional preciseness
• General corrosion resistant

Our Chromium Molybdenum WP91 Pipe Fittings are extensively used in many industrial applications such as gas processing, petrochemicals, pharmaceuticals, condensers, power generations, pulp, and paper, etc. We provided test certificates to the buyers like MTC in accordance with EN 10204-3.1/3.2, NABL approved lab testing report, radiography testing report, etc. The product testing is conducted at our industry to check the strength of the fittings. The tests done are PMI-IGC test, hardiness test, chemical test, mechanical test, etc. Thus no bad quality of fittings are provided to the clients.
