The hot-rolled steel pipe adopts German technology manufacturing equipment and advanced eddy current flaw detection equipment; internal burr removal and cold diameter reduction process equipment imported from the United States to ensure that the inner wall is smooth and smooth without damage and the weld seam is reprocessed; the most advanced automated natural gas high temperature in the country Annealing furnace, the annealing temperature reaches 1000°C, eliminating the internal stress generated during the steel pipe manufacturing process; the most advanced roller-type pipe making and reducing equipment in the country; the hydraulic test process is changed to a 100% hydrostatic conventional process, and the pressure is not Less than 60 kg to ensure product quality. Well-equipped chemical laboratories, physics laboratories, universal material testing machines, Rockwell hardness testers, and other high-end inspection and testing equipment provide a reliable guarantee for product quality.
Scope of application of hot-rolled steel pipes: This product is widely used in medium and low-pressure fluid transportation pipelines, gas pipelines, natural gas pipelines, water supply pipelines, sewage treatment pipelines, air conditioning pipelines, fire protection pipelines, construction projects, chemical projects, petroleum pipeline projects, heating projects and equipment engineering, etc. are national “Ninth Five-Year Plan” key high-tech promotion projects and national “Torch” plan projects developed in the past two years, and are suitable for the oil and gas industry. Water supply and drainage engineering, chemical industry, electric power industry, agricultural irrigation, and urban construction. It can also be used for gas transmission pipelines and can be used as structural pipes for piling, bridges, docks, roads, etc.
