Our main products are hot rolled steel tube, high frequency and straight welded steel tube and hot enlarged steel tube. Hot rolled steel tube includes the normal structural using steel tube and the low to medium-pressure fluid using steel tube, which is made of high frequency and straight welded steel tube with removing burrs in it, chilling its diameter and annealing at the high temperature of 1000℃(1832℉) to eliminate the inner stress absolutely during the course of steel tube-making and make weld seam, metallographical organization and mechanical function in best performance. Then it passes through the 100% still water test with more than 80 kilograms pressure. Furthermore, we have perfect chemical laboratory and physical laboratory to assure its quality.Our products contain high-TECH and added value with even thick and RMB500 to RMB1500 cheaper prices per ton than traditional seamless steel tubes, which are widely used in coal gas pipelines, petroleum pipelines, natural gas pipelines, water supply pipelines, sewage processing pipelines, air conditioning pipelines, fire fighting pipelines, constructional engineering, thermoelectricity pipelines, mine pipelines, steam pipelines, steel structures and etc. It’s been proved definitely that our qualities have already met our customers’ satisfaction and obviously they are exact the updating and upgrading of traditional seamless steel tubes.
