SSAW steel pipe will become a very important anti-corrosion material in future production and use. So, what is SSAW steel pipe? What is the insulation treatment method of SSAW steel pipe? Below, the editor will introduce it to you.
SSAW welded pipe is a name for SSAW steel pipe, generally referring to SSAW steel pipe with a diameter greater than 1 meter. Steel pipes should be subjected to water pressure, bending, flattening and other tests, and have certain requirements for surface quality. The delivery length is usually 12 meters, and fixed scales are usually required.
SSAW steel pipe is a hot-rolled strip steel bent into SSAW shape, and SSAW-shaped steel pipe is made of steel tape or alloy square steel. The correct use of SSAW steel pipe directly affects the service life of the steel pipe. Therefore, when assembling SSAW steel pipes, relevant specifications must be met to avoid serious impact on subsequent use.
Usually, ordinary seamless steel pipes should be used for outdoor steam pipes, and threaded steel pipes (SSAW seam electric welded steel pipes, SSAW steel pipes) are generally used for condensate and supply and return hot water pipes. Pipeline bends use simmering or stamping elbows, and diameter reduction uses stamping heads. Valves usually use flanged stop valves and one-way valves. Pipes are connected by welding and flanges. Small-diameter pipes are connected to steam traps, exhaust valves, and drain valves. Generally, black iron pipes, finished pipe fittings, threads or welding can be used. Exhaust valves and drain valves are threaded stop valves.
During the construction process, if it is necessary to pre-lay relevant pipelines with stone piers or sacks, the cushion design must have a solid foundation to prevent accidents caused by pipeline rolling and injuring people; it is strictly forbidden to use frozen soil and stones as cushions for SSAW steel pipes.
Urban drainage SSAW steel pipes account for a large proportion on the market. Double-sided submerged arc SSAW welded steel pipes feed strip steel into the welded pipe unit. Through multi-roller rolling, the strip steel is gradually rolled up to form a round tube billet with an open gap. Adjust the pressure of the extrusion rollers to control the weld gap to 1~3mm, and make the weld ends flat. There are two main uses for the repair of thick-walled SSAW steel pipes. One is to transport liquids, such as water supply.https://www.baowi-steel.com/products/ssaw-steel-pipe.html
