Alloy Steel Pipe

Schedule 40 ASTM A335 Chrome Moly Welded Pipe and Low Alloy Seamless Pipe supplier in India for High Temperature

ASTM A335 Chrome Moly Pipe is a category of pipe that has chromium and molybdenum in the content to improve the corrosion resistance and the strength of the material. There are different grades such as P5 come off P9, P living up to P91. Each grid has different composition and different mechanical properties. The elements included in all of these grids are carbon manganese phosphorus sulfur Silicon chromium and molybdenum. ASME SA335M Alloy Steel Pipes come under the AST M8335 and ASME SA335 standard specifications. These pipes could be made as seamless cold rolled or cold drawn pipes. The outer diameter of the pipes varies from 3 by 8 inches to 30 inches in nominal bore size. High Strength Low Alloy Steel Pipe Can come in different schedules and wall thickness is depending on the outer diameter and the pressure capacity of the pipe. There are schedules 20 through schedules XXS in these pipes with the whole thickness wearing up to 250 millimeters. We are Alloy Steel Pipe Supplier In India in More than 25 countries

Leading Manufacturer of ASME SA335M Welded Pipes & Low AS ERW Pipe

The length of the pipe varies as well. It can range from 5 to 7 meters, 9 to 30 meters in single random, double random or custom cut to length sizes. The pipe ends very as well. chromoly alloy steel pipes Can have plain NS, be build ends, coupling type of ends. These pipes can be delivered as rolled, cold drawn, normalizing, thermodynamical rolled, or thermomechanical rolled, normalizing formed, normalized and tempered or quenched and tempered. ASTM A335 ERW Pipe can have different strength values depending on the grades. The gradeP91 is the highest strong in terms of tensile and yield strength. it has up to 415 MPA minimum yield strength and up to 585 MPA minimum tensile strength.
