1: Q: What’s the classification for rectangular tube ?
A: Rectangular tube production process classification
Square tube according to the production process points: hot-rolled seamless square tube, cold drawn seamless square tube, squeeze seamless square tube, welding side tube.
Which is divided into:
(A) according to the process points - arc welding square tube, resistance welding square tube (high frequency, low frequency), gas welding square tube,
(B) by welding seam - straight seam welding pipe, spiral welding pipe
2: Q:What is the rectangular tube ?
A: Rectangular tube is a hollow strip of steel, also known as flat tube, flat tube or square tube (as the name suggests). In the bending, torsion strength of the same, the lighter weight, it is widely used in the manufacture of mechanical parts and engineering structure.
3: Q : How long for the guarantee period ?
A : Guarantee period can delay to 30 days after clients recieved the pipe in the destination port .
Square & rectangular tube, also known as square and rectangular cold-formed hollow steel, referred to as square tube and rectangular tube, code-named F and J
1, square tube wall thickness of the allowable deviation, when the wall thickness of not more than 10mm shall not exceed the nominal wall thickness plus or minus 10%, when the wall thickness is greater than 10mm when the wall thickness of positive and negative 8%, corner and weld area Except for wall thickness.
2, square tube of the general delivery length of 4000mm-12000mm to 6000mm and 12000mm majority. Square tube allows the delivery of not less than 2000mm short and non-foot products, can also be delivered in the form of interface tube, but the demand side should be used in the interface tube cut off. Short and non-stop product weight does not exceed 5% of the total delivery volume, for the theoretical weight greater than 20kg / m square tube should not exceed 10% of the total delivery volume,
3, square moment of curvature per meter shall not be greater than 2mm, the total curvature shall not be greater than the total length of 0.2%
