Product Description
▊ Tianyingtai（TYT） is committed to long-term development, creating high-quality products and services, with the same pursuit of quality and service, stable, strong, long-term cooperation raw material suppliers, such as Haigang, Yurunde, etc., to maximize the consistency and stability of materials, product appearance and internal quality.
▊ Raw materials grade : Q195, Q235B and Q345...
▊ High-frequency straight seam welded steel pipe is also called straight seam high-frequency electric resistance welded steel pipe. Its characteristics are: high welding speed, small welding heat affected zone, welding can not clean the work piece, weld thin wall pipe, weldable metal pipe.
▊ The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The welded joint is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe. The surface is smooth, high precision, low cost and low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating.
▊ The welding method of high-frequency welded steel pipe and submerged arc welded pipe is significantly different. Since the welding is done instantaneously at high speed, the difficulty in ensuring the welding quality is much higher than that in the submerged arc welding method.
▊ In November 2014, it was recognized as “Tianjin Famous Trademark” by Tianjin Market and Quality Supervision Committee. The steel pipe produced and sold by the company was rated as “Tianjin Famous Brand Product” by Tianjin Municipal Government. and keep for many years.
