Seamless steel pipe used in the world are very broad, and this type of pipe material production in China has a special standard, which has included the most conventional of seamless steel tubes, seamless steel pipe plant in delivery fluid seamless pipe, while businesses get the pipes must be of a professional quality specification, while at the same time during the inspection, we have to understand is that this pipe-like material meets the size and shape of a standard we need. In addition to this conventional seamless steel tubes, as well as dedicated against high temperature high pressure boiler seamless steel seamless pipe, as well as the need to use high-pressure chemical fertilizer equipment, piping material steel pipe, from the scope of the use of point of view, seamless steel pipe on the use of the whole range should be considered is relatively extensive. The main difference between hot and cold are: 1, cold-formed steel section allows local buckling occurs seamless high pressure, which can make full use of the bearing capacity after buckling rods; and hot-rolled steel section does not allow local buckling occurs. 2, for different reasons, and cold-rolled steel hot-rolled steel residual stress, so the distribution of the cross section is also very different. Cold-formed steel residual stress distribution in the cross section is curved, and hot rolled steel or welded steel section on the residual stress distribution is a film type. 3, hot-rolled steel of freedom high torsional stiffness than the cold-rolled steel, hot-rolled steel so torsional performance is better than cold-rolled steel.
