Shandong Liaocheng Polygram steel pipe manufacturing company; is a professional production of cold drawn steel, hot-rolled steel in the modern enterprise, the company is located in Liaocheng City, Shandong Province Economic Development Zone Industrial Park, north of Jeju Museum Highway, the company has large and small hot-rolled cold-rolled seamless steel pipe seamless steel pipe mill and 16 production lines, annealing furnace three horseshoe precision steel tubes, cold-drawn units, mainly produce diameter 8mm-121mm wall thickness of 1mm-30mm of cold drawn steel, hot-rolled unit, the main production of 89mm-426mm wall thickness 5mm-70mm hot-rolled seamless steel pipe, seamless steel pipe production company are GB GB / T8162 structural tubes, GB / T8163 fluid pipe, GB / T3087 low pressure boiler tubes, GB / T5310 high-pressure boiler tube , GB / T6479 fertilizer tube, GB / T9948 petroleum cracking tube performance standards. Production materials are: 10 #, 20 #, 35 #, 45 #, 16Mn, 27SiMn, CrMo910,15CrMo, 35CrMo, etc., can not say more than the lowest price of the lowest dare, I will discount the price, wholesale and retail ways, provide you with fast quality service, welcome new and old customers to negotiate, Power Conference. Our products are widely used in electric power, chemical, pharmaceutical, oil refining, natural gas, shipbuilding, metallurgy, mining, heating, water treatment, environmental protection, piling, steel and many other industries. Thick-walled seamless steel high-pressure principle principle thick walled high pressure seamless steel high pressure seamless steel pipe production works. High-pressure boiler cares includes the following steps: Step 1, material preparation; step two, tube heating and rotary piercing; step three, capillary dressing; Step four, thermal expansion deformation sizing; Step five, heat treatment; step six, straightening ; step seven, the mill; step eight, correction; step nine, outside grinding; Step 10, flaw detection; 11 steps, then finishing, final inspection and packaging. The present invention can be produced only in the range of a large group from the high-grade alloy seamless steel pipe, and the investment is relatively small, high product quality, high production efficiency, lower production costs. The main production process high pressure boiler steel tube and billet heating, perforated tube, pipe extension, rolling steel pipe, pipe sizing and reducing, cooling and finishing steel or can be said heating hot steel perforated embryos . rolled pickling spray head cut cold drawn carbon burning packaging products manufacturing method of a petroleum cracking precision steel tube plant in Shandong, characterized by: setting will have more of a rolling mill roll stand to each other in different rolling direction configure multiple continuous mandrel mill Liaocheng precision steel tubes, after such a manufacturing production line rolling of seamless steel pipe, steel pipe wall thickness was measured in the circumferential direction after rolling on the multi-point, according to its both ends of each axis position precision steel measurement result, at least control the mandrel mill of the final rolling mill roll the base station, so uneven wall thickness to a minimum. Wall thickness error is relatively large walled alloy seamless Liaocheng Polygram Pipe Manufacturing Co., Ltd. sold all steel implementation of international GB8162-2008 (structural pipe), GB8163-2008 (fluid pipe), GB3087-2008 (low and medium pressure boiler tubes), GB5310-2008 (high-pressure boiler pipe), GB6479-2000 (fertilizer dedicated pipe), GB9948-2006 (petroleum cracking tube), etc., made of 20 # 35 # 45 # 16Mn 27SiMn 15CrMo 12Cr1MoV 35CrMo Cr5Mo 10CrMo910 T91 and so on.
