Production Notes of SSAW Pipe Pile


SSAW Pipe Pile in the production process, we need to pay attention to a series of matters. Except for the following test items, according to the API standard and other relevant standards and the special requirements of some users, but also the need for steel, steel pipe and other tests Destructive tests, including physical and chemical properties of the raw materials into the plant sampling, visual inspection of 100% steel .


Production Notes of SSAW Pipe Pile

A. Oiled marking: steel after passing were oiled to prevent corrosion, and according to user requirements for marking.

B. Leveling Milling: The flat steel anvil machine so that the original curl, and then through the edge milling machine for two-sided steel milling, so as to meet the requirements of the plate width, plate edge parallelism and groove shape.

C. Shear molding: the steel plate production line along the outer edge of the spiral curl into a tube.

D. Butt cut: double-sided submerged arc welding using advanced technology to pre-welding, internal welding, outside welding. The welded steel pipe using a plasma-foot cut to specification length.

How to Increase the Stability of the SSAW Pipe Pile?

After the production of SSAW Pipe Pile, it should be stored.If we don’t do some measures to keep its stability, it will rust and be corroded. So we will talk about how to increase the stability of the spiral welded pipe today. Generally speaking, we have followed methods:

Small and medium-sized steel, wire rod, rebar, steel pipe with medium diameter, wire and wire rope, etc., can be stored in well-ventilated shed, but must put covering in the upper part of the goods and underlay at the bottom of the goods.

Some small steel shape, sheet steel, steel strip, silicon steel sheet, small diameter or thin-walled steel pipe, all kinds of cold-rolled or cold-drawn steel and the metal products with high prices and easy-to-corrode can be stored in warehouse.

The ground or warehouse to store spiral steel pipe should choose the place where is orderly and clean, and it is easy to fluently drain away water. It should stay away from the factories and mines that products harmful gases or dust. We also need to remove the weeds and all debris to keep the steel clean on the ground.

Large-scale structural steel, steel rail, large diameter steel pipe, forgings, etc. can be opened stack.

In the warehouse, SSAW Pipe Pile should not be stacked with the acid, alkali, salt, cement and other materials that have corrodibility on steel together. Different varieties of steel should be stacked separately, to prevent confusion and prevent contact corrosion.
