Spiral Pipe (2)


spiral pipe


Double-sided submerged arc welding spiral steel pipe, which has the advantages of high bearing capacity, small resistance, low temperature resistance, corrosion resistance, easy installation and maintenance, etc., is becoming more and more popular in the oil and gas, pulp transport, urban construction and other industries.


  1. Spiral PipeDuring the steel tube forming process, the steel plate deformation is uniform, the residual stress is small, and the surface does not produce scratches.The machined steel pipe has more flexibility in the size and specification range of diameter and wall thickness, especially in the production of high steel grade thick wall steel pipe, especially in the aspect of large diameter thick wall steel pipe, which has incomparable advantages over other processes and can meet more requirements of users in the steel pipe specification.


  2.  Spiral Pipe Using the process of pre-welding and then internal and external welding (fine welding), the welding can be realized in the best position, and it is not easy to have defects such as wrong side, welding deviation and lack of penetration, so it is easy to control the welding quality;


Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600. 45 steel is high quality carbon structure steel, Spiral Pipe the hardness is not high, easy cutting, mold is often used as a template, pin, guide column, but must heat treatment.1. No. 45 steel is qualified if its hardness is higher than HRC55 (up to HRC62) after quenching and before tempering.The highest hardness in practice is HRC55 (high-frequency quenching HRC58).The heat treatment process of carburizing and quenching shall not be used for seamless steel tubes.


Spiral Pipe is widely used in Spiral Pipe all kinds of important structural parts, especially those connecting rod, bolt, gear and shaft which work under alternating load.But the surface hardness is lower, not wear-resisting.The surface hardness of parts can be improved by quenching and tempering.Carburizing treatment is generally used for surface wear, the core of the impact resistant heavy parts, its wear resistance than quenching + surface quenching high.
