Longitudinally Submerged Arc Welded Steel pipes, LSAW

Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber, long-distance pipelines for oil and gas a small number, the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW), spiral submerged arc welded pipe (SSAW), LSAW steel pipe (LSAW) three. PIPE LINE - IBSQSSAW pipe is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral. Application:Bridges, construcion , port , water, oil and chemical industry. Pipe - Nucor SkylineNucor Skyline:Pipe 3 Manufacturing Process Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube by passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to produce a bond.

Production process of large-diameter straight seam steel

The use of large-diameter straight seam steel pipes is mainly used for body supporting parts, such as bridge piling, subsea piling, and high-rise building piling. The materials used for large-diameter straight seam steel pipes are generally Q345B and Q345C. Q345D is also used in areas with low temperatures. Q345E large-diameter straight seam Production process of large-diameter straight seam steel The use of large-diameter straight seam steel pipes is mainly used for body supporting parts, such as bridge piling, subsea piling, and high-rise building piling. The materials used for large-diameter straight seam steel pipes are generally Q345B and Q345C. Q345D is also used in areas with low temperatures. Q345E large-diameter straight seam Q345B low-alloy seamless steel pipe puts a safety mat on Q345B low-alloy seamless steel pipe is expected, the property market regulation will remain tight for a long time. The short-term is to maintain policy rigidity, and the long-term is to promote the construction of long-term mechanisms.

Which is Better for Bridge Support Columns to Choose

Nov 02, 2020 · Straight seam steel pipes are generally used for bridge support columns, because the performance of straight seam steel pipes is a little worse than seamless steel pipes and stronger than spiral steel pipes. The price is also cheaper than seamless steel pipes and more expensive than spirals. Yuanfang Steel Pipe-RobinCangzhou Yuanfang Steel Pipe Co., Ltd. is a production and export trade as one integrated company, we specialize in the production and study of welded steel pipe and seamless pipe, round steel pipe, square steel pipe, rectangular steel pipe, straight seam welded steel spiral welded pipe , ERW, LSAW,etc. We have an experienced sales team and R & D mast section-Q345B straight pipe advantages - CLSJ HOISTTranslate this pageThe mast section of the construction hoist is mainly composed of pipes, frames, and racks.
