The Specification of ERW Steel Pipe

Some consumers haven't a awfully clear construct concerning of the definition, manufacture processing and application of ERW steel pipe. Today, Prime steel pipe can provide specification of ERW pipe in details for all of you.

The definition of ERW pipe

ERW pipe (also known as ERW steel pipe) is that the abbreviation resistance Welded Pipes. resistance fastening refers to a bunch of fastening method (including spot and seam fastening) that turn out conglutination of faying surfaces wherever heat to create the weld is generated by the ohmic resistance of fabric combined with the time and therefore the force accustomed hold the materials along throughout welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

ERW tube manufacturing process

ERW steel pipe is manufactured by rolling metal and then welding it longitudinally across its length. ERW steel pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24”OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.

Typical ERW tube manufacturing process of Prime Steel Pipe generally involves the following stages in a step by step procedure.

ERW steel pipe’s application

ERW steel pipes are used in various engineering purposes, fencing, scaffolding, line pipes etc. It is available in lengths from single random to 120 feet depending on mill capability. What's more, ERW steel pipes are usually used for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a powerful protection for cables by telecommunication Department, Structural functions etc. ERW steel pipe is obtainable with sq. ends or beveled for fastening, rib and matched and victaulic grooved. Surface end of it's on the market in black or vacant, or with protecting coatings.

Prime Steel Pipe have a awfully massive production capability of ERW steel pipes, in order that we are able to manufacture ERW pipes and tubes of various size and form supported the purchasers necessities.

Pipe Application: Oil Pipeline

The main type of pipe that used in Oil pipeline is carbon steel pipe, including seamless steel pipe and welded steel pipe.

Seamless steel pipe is applicable to transport strong corrosive oil or transport in the high temperature conditions as it has the characteristics of high strength, specifications and more features. The technology of seamless steel pipe includes hot rolling and cold drawn.

Welded steel pipe includes LSAW steel pipe and SSAW steel pipe. The process characteristics of carbon steel pipe leads the steel pipe to tend to become brittle at low temperatures, so it is mainly applied to the normal temperature pipeline, the use of pipe temperature should not exceed 300 degrees Celsius. In general, the temperature of ordinary carbon steel pipe is between 0 to 300 degrees Celsius. If using the high-quality carbon steel pipe, the temperature range can be broadened from -40 to 450 degrees Celsius. The experimental pressure of the steel pipe is generally 1.5 times of the nominal pressure. When the temperature of the material delivered does not exceed 200 degrees Celsius, the working pressure is the nominal pressure. When the temperature exceeds 200 degrees Celsius, the working pressure should be correspondingly lower than the nominal pressure.

Prime Steel Pipe as an excellent manufacturer, has complete production lines to produce SSAW steel pipe. No matter what requirements you have, Prime Steel Pipe will surely make you satisfied.
