To pass through the cutting head and cutting tail straight hair volume, trimming and straightening, level off of multichannel time after finishing line processing, cutting board or heavy volume, again become namely: hot rolled steel plate, flat hot-rolled coil, slitting and belt and other products. Cold drawn finished products of high precision, good surface quality. Products can be very rough as-cast or Quick Connector wholesales cold dial. We have pipe inventory of this kind of pipe,pls visit our website if you need.5. High precision to do small batch3.2. .4. Straight hair volume of head and tail often show tongue shape and fish shape, thickness and width accuracy is poorer, side often exists defects such as wave shape, folding, tower. Steel pipe is superior performance, dense metal. Hot rolling finishing if volume after acid pickling to remove scale and greased Refrigerant charging pipe the hot-rolled pickling plate volumes. The volume weight is heavier, coil diameter is 760 mm. The outer diameter smaller.2, 20 # precision tube is the product appeared in recent years, mainly is the inner hole, the size of the outer wall with strict tolerance and roughness.The characteristics of the 20 # precision tube1. The steel pipe transverse area is more complex.1, 20 # precision tube main characteristic is a welding seam, can withstand greater pressure.20 # precision tube difference after hot rollingHot-rolled # 20 precision work slab or slab continuous casting round billet as a raw material, by step heating furnace, high pressure water descaling into the roughing mill, after roughing expected by the cutting head, tail, and then into the finishing mill, and the implementation of computer control rolling and finishing after through laminar cooling and the winder, become straight hair volume
