The Application of SSAW in the Urban Central Heating Shipment and Ocean Engineering
The Application of Spiral Steel Pipe in the Urban Central Heating Urban central heating is generated by the concentrated heat of steam, hot water supply mild steel pipe network through a city or parts of the heating used in the production and living way, which consists of heat, heat networks, hea...Read more -
Spiral steel pipe temperature control and installation process
Spiral steel pipe temperature control Spiral steel pipe welding temperature is mainly affected by the high-frequency eddy thermal power, high-frequency eddy current heating power is mainly affected by the frequency, power and thermal eddy current excitation frequency is proportional to the square...Read more -
Seamless steel pipe piercing
Piercing is the first step of hot-rolled seamless steel pipe deformation, and its role is to solid hollow tube billet dressed as capillary. Due to wear a capillary surface defects or eccentric (uneven thickness) is difficult to eliminate or reduce the deformation process, therefore, the quality o...Read more -
Alloy steel pipe
Alloy tube (Alloy pipe) is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this steel pipe inside containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the mor...Read more -
Advantages of Rectangular Pipe Heat Treatment
In order to improve the surface hardness and wear resistance of rectangular pipe, it can be processed some of the surface, ie the surface of pure flame of fire, high, intermediate frequency surface hardening and some chemical treatment and the like. Generally high, intermediate frequency surface ...Read more -
Quality control of structural steel pipe
Structural steel in its wall thickness, good materials, processing technology and stability, becoming the first choice for large domestic and foreign oil and gas pipe project. In the large-straight seam welded steel pipe joint structure, weld and heat affected zone is the easiest place to produce...Read more
