Limited to steel factory seamless steel pipe specifications limited, according to the final consumer's needs so the thermal expansion steel pipe has been born, the thermal expansion steel pipe specifications model is more randomness, generally according to the customer's needs, the thermal expansion steel pipe is what we often say heat expansion pipe, the density is relatively low but the shrinkage very strong steel pipe, (seamless steel pipe) can be shortly called heat expansion pipe.
