Provide safe and reliable stainless steel pipe for industry.Production base No. 1 is located in Zhangguo Industrial Science and Technology Park, Xinghua City, Taizhou City, China's Stainless Steel City. After three years of rapid development, the company established production base No. 2 in the same area in 2019.Specializing in the production of stainless steel BA/EP tubes, stainless steel precision seamless tubes, stainless steel bright seamless tubes, stainless steel heat exchange tubes, stainless steel clean tubes, customized tubes, etc.The materials are mainly 304, 304L, 316L, 321, 347H, 310S, 904L, 2205, 2520, 2507, C276, etc.The products are widely used in mechanical equipment, automobile manufacturing, shipbuilding industry, metal machining, hydraulic equipment, semiconductor, photovoltaic, instrumentation, biomedicine, food industry, aerospace, petrochemical, pressure vessels, heat exchangers, automatic industrial rail transit, high-pressure boilers, water conservancy and power and other industries.The company strictly follows ASTM A269/ASTM A270/ASME-BPE/EN10216-5/EN10305-1/ISO 1127 standards to organize research, development, production, control and sales of stainless steel seamless tubes. The main production equipment is LD-80 multi roll cold rolling pipe mill, LG-60-SG full-automatic cold rolling pipe mill, LG-40-SG full-automatic cold rolling pipe mill, LD50, LD-30, LG-20-H cold rolling pipe mill, LB-15T oil drawing machine, 1080 vacuum bright annealing furnace, and other complete sets of stainless steel pipe production lines. It has advanced steel pipe quality testing equipment and technology such as eddy current testing, hydraulic testing, spectral testing, hardness testing, etc.To establish a long-term integrity and achieve immortality through quality: we take high quality, high efficiency and credit as our business philosophy. Solve the customer's worries and solve problems from the customer's perspective. Keep looking at yourself and the needs of the industry!The multi roll cold rolling mill equipped in Jiangsu Jiangsu Metal Technology Co., Ltd. is the key equipment for manufacturing sanitary seamless stainless steel pipes. With the cold drawn steel pipe as the blank, the error between the internal and external diameters of the cold rolled pipe and the wall thickness shall be ± (0.02 ~ 0.05) mm, and the internal and external surface finish of the pipe (R a) ≤ 0.8 μ m. The tube can be made to a wall thickness of 0.8mm, and then polished. The internal and external surface finish (Ra) of the tube can reach 0.2~0 four μ m .The defect of the cold rolled tube is hard, that is, the yield coefficient is large, and it is not suitable for flaring and bending, so the hot melt treatment (annealing) should be carried out. In general, after the stainless steel pipe is treated in an ordinary thermosetting furnace
