ASCENT PIPE CO. PVT LTD
MANUFACTURING UNIT FOR LARGE DIA PIPES
We are one of the leading manufacturers of large diameter stainless steel pipes in India. Our manufacturing unit at Manesar, Gurgaon produces pipes as per ASTM A358 standard.
Our range of production in stainless steel pipes is from 3" to 24" NB and OD sizes, thickness 3mm to 12mm in grades 304, 316,310 and 202. The stainless steel pipes are fabricated from plate in standard length of 6 meters or as per customer's requirement.
The edges of the plate are first planed parallel in the shape of a double Y bevel. In the forming process, the plate is first bent into a "U" and then into an "O". Before TIG welding takes place, the open edges of the slit pipe are tack welded together. The pipes are than sized and straightened using hydraulic press to meet close tolerances on diameter, roundness and straightness. Seam of the pipes is checked visually, inside and outside. Our internal quality checks can be augmented by X-ray examination and manual UT.
The final inspection includes additional checks of the entire pipe at diameter, wall thickness, bevel edges, roundness, etc. on the pipe body and ends.
