Product Description Product DescriptionSeamless steel pipes are formed as a whole using hot rolling or cold drawing processes, with no weld seam structure, dense and uniform material structure, and smooth and flat inner and outer surfaces. The product has high precision in controlling wall thickness, excellent cross-sectional roundness, stable mechanical properties, and combines high strength and good ductility. Multiple materials such as carbon steel, alloy steel, and stainless steel can be selected to adapt to high temperature, high pressure, and extreme corrosive environments, with outstanding fatigue resistance and impact resistance. The production process strictly follows the international standard system, ensuring zero tolerance for defects through multiple non-destructive tests. The surface can be treated with sandblasting, acid washing, etc. to improve comprehensive performance and meet long-term use requirements under harsh working conditions. Functional features Seamless steel pipes exhibit excellent sealing performance in the field of high-pressure fluid transportation, effectively avoiding the risk of medium leakage, and are widely used in key pipelines of energy and chemical systems. Its uniform mechanical properties provide reliable structural support for heavy machinery and equipment, with a load-bearing capacity far exceeding that of conventional pipes. It exhibits excellent thermal conductivity and temperature resistance in heat exchange systems, adapting to frequent thermal expansion and contraction conditions. Precision cold drawn seamless tubes can achieve high-precision assembly of complex mechanical components, and their wear resistance is significantly enhanced after surface hardening treatment. Special material steel pipes meet the extreme environmental protection requirements of cutting-edge fields such as nuclear power plants and deep-sea equipment.Our company's products have outstanding core advantages, comprehensive usage coverage, and comply with engineering standards from multiple countries. The specific details are as follows.Core advantages Compared to welded steel pipes, seamless pipes have significantly improved overall structural strength, completely eliminating the hidden danger of weld cracking and extending their service life by multiple times. A mature process system ensures highly stable product performance, with extreme pressure testing performance far exceeding industry standards. The full size specification coverage capability meets the diversified needs from micro instruments to large equipment, and customized heat treatment technology can optimize special indicators such as corrosion resistance and wear resistance in a targeted manner. The global certification system supports access to engineering projects from multiple countries and provides value-added services such as professional pipe end threading and flange welding. Large scale production combined with flexible supply mode, balancing bulk order delivery and emergency demand response.Application field Energy development: oil and gas well casing, shale gas transmission main pipeline?

Emerging fields: hydrogen energy storage and transportation containers, semiconductor specialty gas delivery systemsCompany ProfileShandong Guowei Metal Co., Ltd. was established in September 2017 with a registered capital of RMB 120 million. The production base is located in Dazhangjia Town, Shen County, Liaocheng City, Shandong Province, China, with a total area of about 140 acres (planned to exceed 100000 square meters), and a standardized factory building of 23400 square meters has been built. The company focuses on the research and development, production, and sales of various steel products such as straight seam welded pipes, seamless welded pipes, galvanized pipes, steel plates, steel coils, and color coated steel, with an annual production capacity exceeding 300000 tons. There are currently more than 170 employees, including 46 with college degrees or above, 16 professional technical and testing personnel (including senior personnel in special occupations and non-destructive testing personnel), 22 sales teams, and over 100 skilled workers.The company is equipped with multiple modern steel pipe production lines, producing various steel products including Q195/Q215/Q235/Q345, ST37-2/S400/ST52-3, 16Mn/J55/20 #, SM490A/SM520A, ASTM A106 GR.B. These include plain carbon steel, high-quality steel, and alloy steel. The product specifications include but are not limited to: outer diameter of 25-159mm, wall thickness of 3.0-12.0mm, and other specifications. The core production line is equipped with a German roll forming unit and an American Sematur solid-state high-frequency welding machine, which can produce ultra thick wall straight seam welded pipes. Multiple RT1-660-6 resistance furnaces are equipped to implement normalizing technology, combined with diameter reduction technology to achieve seamless processing of welded pipes. At the same time, fully automatic straightening and cutting equipment is configured to effectively solve the accuracy defects of traditional hydraulic presses that rely on manual experience adjustment, ensuring excellent product quality and customer delivery.As an integrated enterprise of research and development, production, and sales, the company is accelerating its layout in the international trade field based on advanced production technology and mature sales system. By continuously optimizing localized operations and globalization strategies, we are committed to building long-term and stable cooperative relationships with global customers. Adhering to the corporate spirit of "integrity, efficiency, pragmatism, and dedication", and practicing the business philosophy of "quality foundation, service victory, brand credibility, and market win-win", the company will continue to promote industrial upgrading, consolidate its leading position in the steel pipe and steel industry, and make greater contributions to economic development, social development, and customer cooperation.Our AdvantagesPackaging & ShippingExhibition DisplayCertificationsFAQQuestionAnswerQ1.
