The Erw Stainless Steel Pipe can range from smaller sizes up to 24 inches outer diameter. OurErw SS Pipesare manufactured in accordance with international requirements and are examined for quality. We additionally supply Erw Stainless Steel Tube & Stainless Steel Electric Resistance Welding Pipes in different material grades than the 304 and 316 grades of chrome steel.
Oshwin Overseas is a leading Stainless Steel Erw Pipe manufacturer in India and we produce and sell different grades, types and sizes of the pipes. Our product vary consists of essentially the most used SS 304 Erw Pipe merchandise in addition to the second most used SS 316 Erw Pipe products. The erw pipes are electric resistant welded from either strips or coils in a longitudinal path to add strength to the pipe. There are different dimensions and standards of these pipes. The Erw Schedule forty Pipe is one of the medium range schedules that allows medium vary pressure containment of the pipes.
The strip then passes by way of a series of contoured rollers which cold-kind the material right into a round shape. The edges are forced together under pressure as a butt joint after which welded by heating the material to temperatures above 2000° F. The flash weld that has fashioned is now removed from the outside diameter of the tube. Once the weld has been examined the tube then passes through a collection of sizing rolls to realize its precise finished dimension, after which the tube is then straightened and minimize to length.
These weld seams are then eliminated through the finishing course of. The welded pipe is heat treated, inspected and hydro tested. ERW Pipe is produced in sizes from 1/8 to 24 in NPS. ERW welded pipe is produced from flat sheet metals.
We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
Cold Rolled,Hot Rolled Stainless steel Plate and sheets
- Oshwin Overseas is a leading Stainless Steel Erw Pipe producer in India and we produce and sell totally different grades, sorts and sizes of the pipes.
- The Erw Schedule 40 Pipe is one of the medium vary schedules that permits medium range pressure containment of the pipes.
- The erw pipes are electric resistant welded from either strips or coils in a longitudinal direction to add strength to the pipe.
- Our product range consists of probably the most used SS 304 Erw Pipe merchandise in addition to the second most used SS 316 Erw Pipe products.
These pipes are principally used in water, oil and different low pressure transportation of liquids. The advantage is the strength along the length of the pipes.
What are the two types of MS pipes?
The two most common types of pipes are welded pipe and seamless pipe. Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe is A53.
Most widespread specification for welded carbon steel pipe is A53. Seamless pipe is made by a course of that requires no welding.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High toughness and impact resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean
What is ERW steel?
ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The material used in the manufacturing process is typically SAE 1010.
In this methodology, the pipe is made from a strip of stainless steel material. The strip is curved into the pipe form and the ends are touched the place the electrical present is passed to produce warmth.
This contains revolving copper disc, fastened alloy Cu contacts and induction coils. These methods raise the temperature of the steel edge to 2600 deg F for efficient welding. The rolling course of exerts a lot stress that it creates a steel welded seam on the outside and inside.
