Alloy square rectangular tube Also known as square and rectangular cold formed hollow steel, referred to as square pipe and rectangular pipe, code F and J respectively

1. Alloy square rectangular tube The allowable deviation of wall thickness shall not exceed positive or negative 10% of the nominal wall thickness when the wall thickness is less than 10mm, and positive or negative 8% of the nominal wall thickness when the wall thickness is greater than 10mm, except for the wall thickness of the corner and weld zone.

2. Alloy square rectangular tube Usually the delivery length is 4000mm-12000mm, with 6000mm and 12000mm in the majority. Square rectangular tube allows delivery of not less than 2000mm short and irregular products, can also be delivered in the form of interface tube, but the customer should remove the interface tube when using. The weight of short and irregular length products shall not exceed 5% of the total delivery quantity, and for square rectangular tubes with theoretical weight greater than 20kg/m shall not exceed 10% of the total delivery quantity

3. Alloy square rectangular tube The bending must not be greater than 2mm per meter and the total bending must not be greater than 0.2% of the total length

4. Alloy square rectangular tube According to the production process: hot rolled seamless square tube, cold drawn seamless square tube, squeeze seamless square tube, welded square tube.

The welded square pipe is divided into
1, according to the process: arc welding square tube, resistance welding square tube (high frequency, low frequency), gas welding square tube, furnace welding square tube

2, according to the weld – straight seam welding square pipe, spiral welding square pipe.

Section Shape Classification

Square pipes are classified according to section shape:

1, simple section of square tube: square tube, rectangular square tube.

2, complex section square tube: flower shaped square tube, open square tube, corrugated square tube, shaped square tube.
