A334 Grade Pipe

ASTM A334 (ASME S/A-333) Pipes grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties. A334 pipe is furnished to nine different grades designated by numbers 1, 3, 4, 6, 7, 8, 9, 10, & 11.

Reliable Pipes & Tubes Ltd. is PED approved manufacturer & Govt. of India recognized Export House, established in 1975. We are supplier of Pipes, Tubes, Tubing, Pipe Connection, Tubular & Oil – gas piping materials for CBM field, Oil & Gas field, exploration drilling sector companies.
