In general, small diameter mild steel pipe, known as small-diameter steel pipe, small diameter steel pipe can be divided into: seamless small-diameter steel pipe, straight seam (also called welding) small-diameter steel pipe.
Generally less than the outer diameter of the tubes 89 are collectively referred to as small-diameter carbon steel pipe. According to different production methods can be divided into hot-rolled tubes, cold-rolled pipes, cold drawn tube, squeeze tubes, hot rolled seamless pipe is generally produced on automatic pipe mill. Solid tube by check and cut into desired length, end to end surface of the perforation in the tube centering and then sent to the furnace heating in punch perforations in perforation while continuing to rotate and advance in the roll and immediate effect to remove surface defects. tube internal gradually formed a cavity known as the capillary, and then sent to the automatic rolling machine to continue rolling and finally by the machine are the entire wall thickness sizing, sizing machine, within specification, the use of continuous pipe mill producing hot-rolled small diameter steel pipe is a more advanced method of putting up a smaller size and better quality small diameter steel pipe, must adopt the method of cold-rolled cold-rolled cold drawn or both are usually on a two roll mill, small-diameter structural steel pipe in the variable section hole slot and does not move the cone-shaped head ring pass rolling, cold drawing is usually in a single chain or double chain drawing machine, extrusion is about to heat a good tube in closed extrusion perforated rods and extruded rod with movement within the cylinder, so that the extrusion extrusion from the die hole of smaller, this method can produce smaller diameter steel pipe.
Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
