ASTM A335 Alloy steel erw pipe dimensions vary according to the ASTM, ASME and API standards. The sizes range from 1/8 inches to 30 inches in nominal bore size. The Seamless alloy steel pipe is very common in precise applications and the tube sizes range from ½ inches to 5 inches in outer diameter. The outer diameter of the products range from 6mm to 2500mm depending on the product and requirement. The High strength low alloy steel pipe manufacturers in India is made up of stronger alloys. The alloying material differs from grade to grade and the mechanical properties vary as well.
Alloy Steel Pipe Manufacturers
Alloy Steel ERW Pipe
The wall thickness of the pipes vary from 1mm to 200mm based on the schedules and pressure requirements. The schedules range from sch20 through XXS. The 1-1/4cr-1/2mo Alloy steel pipe manufacturers in india produce these different types of alloy steel pipes with improved corrosion resistance and strength. The length of the pipes can vary up to 13500mm. The 4140 Alloy steel pipe has 655MPa minimum yield strength and 415MPa minimum yield strength.
This is one of the high tensile pipes in the alloy steel grades. The Welded Alloy steel pipe is used in a range of applications such as oil and gas, petrochemical, power plant, cooler, super heater and condenser applications. The welding of each different grade differs. Most of the Seamless ferritic alloy-steel pipe types can be welded with conventional welding methods. A few grades require particular welding methods and post weld heat treatments as well.
