Buy High Quality Carbon Steel Pipes, With Mill Certification CALL US NOW ! Exports is Our Specialty. Carbon steel pipes are widely available and relatively affordable, making it a popular choice for very large projects such as pipelines.Stainless steel pipes are made from an alloy of steel and chromium, and are one of the more expensive types of pipe on the market.
For instance, a welded pipe has a longitudinal seam that is absent in a Carbon Steel Seamless Pipe. The presence of a seam could be problematic in some instances. For example, in the presence of high pressure, there could be chances of a welded seam failing and if not properly welded, it could get corroded on the seam area.

Difference in Welded Pipe Production Processes:Welded pipes or ERW Pipes are suppliers ERW Pipe Mill IntroductionERW Pipe Mill is specially used for producing high-frequency straight seam welded pipe and square pipe and special shaped pipe .. It is a welding technology that uses skin effect and adjacent effect produced by high frequency current to connect steel plate with other metal materials
ERW steel pipe is one of the main pipe structural material in construction and liquid transfer steel material. It is properly used in bridge building, underground transfer assemble structure ,agriculture, chemical liquid transfer, oil and gas transfer and so on, It will be manufactured by electricity resistance welding. ERW Welded Gi Pre Galvanized Round Scaffolding Steel PipesType:Welded Technique:Cold Drawn Material:Carbon Steel Surface Treatment:Black Usage:Pipeline Transport, Boiler Pipe, Hydraulic/Automobile Pipe, Oil/Gas Drilling, Food/Beverage/Dairy Products, Machinery Industry, Chemical Industry, Mining, Construction & Decoration, Special Purpose Section Shape:Round
Electric resistance welding (ERW Welded Pipe) is used to transport oil, natural gas and other vapor and liquid objects, which can meet various requirements of high and low pressure, and currently occupies a pivotal position in the field of transportation pipes in the world.The electric resistance welding pipe is manufactured by cold forming a piece of steel plate into a High Frequency Welding Pipe Making Machine ERW Tube MillTUBE MATERIAL:Stainless steel, Iron, Carbon steel, Galvanized, etc. PIPE SHAPE:Round Circle, Square, Rectangle, Special shape, etc. USAGE:Water pipe / Fluid pipe / Petrochemical pipe / Aerospace Automobile pipe /Drinking food grade pipe/Hygienic grade pipes Etc. High frequency ERW pipe welding machine tube mill is specialized in producing
Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe.

Square and Rectangular Steel Hollow Structural RHS/SHS can be supplied to IS-4963 / 1968 specifications range from 0.80 MM to 1.20 MM to maximum of 4.00 MM to 6.00 MM wall thickness for Square Hollow Section (RHS / SHS)s & range from 0.80 MM to 1.20 MM to maximum of 4.00 MM to 6.00 MM wall thickness for Rectangular Hollow Section (RHS / SHS)s.The Tubes Welded Stainless Steel Tube Stainless Steel Welded PipeASTM A249 A312 A358 A778 ASME SA 249 SA 312 SA 358 Welded Stainless Steel Pipe. Welded Stainless Steel Pipe Usage:Used for low pressure liquid delivery, such as water, gas, and oil. General, Hydraulic System, Constructural, Decorative/Ornamental Welded Stainless Steel Steel Pipe End:square ends (straight cut, saw cut, and torch cut). or beveled for welding
Common defects for welded steel pipe. We will take a look at some common defects that occur on welded steel pipes and they are explained below:1. Lack of fusion This is simply the poor adhesion of the weld bead to the base metal. A weld bead that doesnt begin at the weld grooves root is known to be incomplete penetration.Differences between ERW Steel Pipe and HFW Steel PipeERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
