1.Introduction of pre-square tube
Coiled pipes are pipes and pipes for processing technological processes, and are the name of general pipes, which are pipes made of long steel coils made of steel strips. The formed tube is then made from a round tube, and the tube is then cut to the required length.
2.The steel strip is manufactured by a special process with pre-square rectangular tubes. After repeated unpacking, the steel strips are processed into coils, tubes, coiled tubes, and then tubes. There are 500 square tubes in each package. Specifications, shaping is also the specification name of the square tube.
3.Galvanized square and rectangular tube specifications:
3.1. The allowable deviation of the wall thickness of the galvanized square and rectangular pipe shall not exceed plus or minus 10% of the nominal wall thickness when the wall thickness is not greater than 10mm, and shall be plus or minus 8% of the wall thickness when the wall thickness is greater than 10mm. Except for the wall thickness in the seam area.
3.2. The usual delivery length of galvanized square tube is 4000mm-12000mm, mostly 6000mm and 12000mm. The square rectangular tube is allowed to deliver short-length and non-fixed-length products not less than 2000mm, and it can also be delivered in the form of an interface tube, but the buyer should cut off the interface tube when using it. The weight of short-length and non-fixed-length products should not exceed 5% of the total delivery quantity, and for square and rectangular pipes with a theoretical weight greater than 20kg/m, it should not exceed 10% of the total delivery quantity.
