Steel pipe processing of the construction process and corrosion requirements
Jan 31, 2018

During the process of steel pipe processing, there are many items to be noticed, The steel pipe components processing are mainly concentrated in the rented field. The site is equipped with one 15t / 20m gantry crane.In order to improve the processing quality, in addition to equipped with general processing equipment, but also equipped with automatic cutting torch, automatic welding machine, sand blasting, painting, film thickness tester and other equipment.

Steel pipe processing construction process

Raw material correction → lofting, material → cutting (cutting or gas cutting) → welding → finished product inspection.

Steel pipe in the factory production of the design of the length of the pipe, weld appearance inspection may not have cracks, partial continuous bite total length less than or equal to 100mm.Manufactured steel pipe without aspiration, kerosene penetration and hydraulic test acceptance, can be sent to the assembly site.

Preservation of steel pipe processing requirements

The steel pipe before brushing anti-corrosion coatings are required on the surface of steel pipe rust treatment, to ensure that the pipe surface is dry, no traces of water, no welding slag, no traces of oil.Pipe wall corrosion: After the surface is cleared, the special anti-corrosion paint brush steel PHA106 primer again, and then brush PHA106 topcoat twice, requires the cured film thickness of 90-100μm.

Anticorrosion tube outer wall divided into the following situations

1. Outside pipeline: After the surface is cleared, the special anti-corrosion coating for steel pipe PHA106 twice, and then brush enhanced UV-resistant PHA106 topcoat twice, requiring the cured film is not less than 100μm.

2. Buried pipe: After the surface is qualified, the special anticorrosive paint for brush pipe PHA106 primer twice, then brush it again PHA106 top coat, required coating thickness of not less than 150μm.http://www.alucncmachining.com/
