ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Square steel tube comes in different sizes, specifications and wall thicknesses. Its uniformity makes it predictable to use and visually appealing. It has a high weight-to-strength ratio. It’s easy to bend, and because square steel tubing is inexpensive, it’s cost-effective- even for large projects.
Rectangular steel tube comes in different sizes, specifications and wall thicknesses. Its uniformity makes it predictable to use and visually appealing. It has a high weight-to-strength ratio. It’s easy to bend, and because square steel tubing is inexpensive, it’s cost-effective- even for large projects.
For the best quality Oval Tubes, we serve as one-stop destination in the international market. Our Steel Oval Tubes are endurable and long lasting. They are extensively used in various industrial and engineering applications. Apart from that, we are identified as one of the reliable Oval Steel Tubes Manufacturers and Suppliers in the country.
The difference between ASTM A53 pipe vs A106 Pipe in spec scope, pipe chemical composition, mechanical properties (tensile & yield strength etc), pipe type.
This article provides an overview of electric resistance welding (ERW). It dicusses high-frequency ERW (contact and induction) and rotary wheel contact welding (AC, DC, and square wave). It describes the differences among the processes, as well as the power supplies and weld rolls.
Electric Fusion Welding(EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.
Resistance welding is pressed welders parts between the two electrodes, and go through to the current use of resistance heat generated by current flowing through contact with the workpiece surface and the neighboring regions to be heated to the melting or plastic state, so as to form metal-bindingways.
ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.
ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.
Galvanized pipe is protected by zinc, so it is not easy to rust, galvanized steel pipe is lighter than seamless steel pipe, if it is used in the balcony, the best light with galvanized pipe
Generally speaking, the welded steel pipes are divided into general welded pipe, galvanized welded pipe, oxygen welding tube, metric system welded tube, transformer tube, welding thin wall pipe and spiral welded pipe etc.
We can produce precision and high-frequency welded steel tubes and pipes with all possible dimensions and shapes available.
Our product finds its usage for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a strong protection for cables by Telecom Department, Structural Purposes etc.
While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness. We are among the leading manufacturers and suppliers of erw pipes and tubes in India. We are also one of the largest exporters of erw pipes and tubes in India. ERW pipes and tubes stands for Electric Resistance Welded pipes and tubes.
Based on the customers requirements we can manufacture erw pipes and tubes of different size and shape. We have a very large production capacity of erw pipes and tubes. ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW pipe is available in lengths from single random to 120 feet depending on mill capability. ERW pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish are available in black or bare, or with protective coatings.
For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.
