Thick wall spiral steel pipe prevents damage

There are many kinds of thick wall spiral steel pipes processed by manufacturers, and steel pipe damage will inevitably occur in the loading and unloading process. The actual precautions are as follows

1, the thick wall spiral steel pipe packaging should be able to avoid falling and damage in normal loading and unloading, transportation and storage.

2. If the buyer has special requirements for the packing materials and packing methods of the thick wall spiral steel pipe, it shall be indicated in the contract; If not indicated, packaging materials and packaging methods are selected by the supplier.

3, packaging raw materials should meet the relevant provisions. If there is no provision for packaging raw materials, they should meet the main use of the reservation to prevent waste and cause environmental pollution problems.

4, if the customer specifies that the thick wall spiral steel pipe can not have collision and other damage on the surface, it can take into account the selection of protective devices in the pipe. Protective devices can use rubber, rope, fiber cloth, plastic products, pipe caps, etc.

5, the thick wall spiral steel pipe in view of the thick wall can choose the measures of internal support or external framework protection. The material of the bracket and outer frame is the same as that of the pipe.

6, the state stipulates that the thick-wall spiral steel pipe should be used in the form of loose weighing, the bundled material should be packed and jammed with steel tape, each way should be not less than two strands, and according to the outer diameter and net weight of the thick-wall spiral steel pipe, the thickness of the spiral steel pipe can not be bundled.

8. The thick wall spiral steel pipe is assumed to have a wire buckle on both sides, which should be prevented by a protector, and be coated with lubricating oil or anti-rust agent on the wire buckle.

Steel pipe on both sides of the crack, according to the regulations, to avoid thick wall spiral steel pipe in the container can be bundled or welded outside the pipe guard bracket

Explain the steps of the manufacturing process

The first is to carry out careful inspection of materials, manufacturers for the production and processing of materials is a lot of demand, manufacturers only enough to ensure the characteristics of the material can guarantee the final production and processing quality, this point in the production and processing must be paid attention to, so that the quality of the manufacturers can meet the requirements.

Secondly, at the time of manufacturing, the spiral steel pipe manufacturers in the choice of welding methods is particular, only the selection of welding methods can ensure the quality of welding, the general industry will be applied in the form of submerged arc welding, the manufacturer shows that the quality of the welded manufacturers will be very good.
