Description
Alloy steel is alloyed with many materials including molybdenum, chromium, nickel, manganese, and a few trace elements. An Alloy Steel Pipe provides moderate corrosion resistance. These pipes are used in applications where the carbon steel pipes cannot suffice. They are designed with excellent mechanical properties. These steel alloy pipes have a tensile strength of minimum 415Mpa and yield strength of minimum 205Mpa. The ASTM A335 Pipe is a high-temperature pipe. These pipes can withstand temperatures up to 375 degrees C. They are widely used in petrochemical, oil and gas, nuclear industries, etc.
Pipes and tubes are produced either seamlessly or through welding procedures. Alloy Steel Seamless Pipe is produced with the help of a single billet and without any welds. They are available in sizes of ½ to 26mm. They are very durable and easy to maintain. The Alloy Steel Welded Pipe is designed by welding pieces of steel together longitudinally. These pipes have an outer thickness of 0.3-50mm. They can be availed in a beveled or a plain end. The Seamless Alloy Steel Pipe is costlier than the welded pipe as it has 20% extra working pressure. These pipes are furthermore resistant to corrosion. The Alloy Steel ERW Pipe is manufactured by passing electricity through steel sheets. These pipes are cold-rolled to give them smooth and desired properties. Our experienced staff makes use of the best raw materials and the latest technology while producing the Alloy Steel Pipe, along with our other products.
The Alloy Pipe Price depends on the wall thickness and the size of the pipe. An alloy pipe is available as less as 130INR per kg to 3,000INR per kg. The Boiler pipe material we used to make boiler tubes and pipes is extremely strong. These pipes suffice in temperatures up to 450 degrees C, and they don’t dissociate easily.
