How To Do Anti-corrosion At The Welding Of 3pe Steel Pipe

How to do anticorrosion at the welding connection of 3pe anticorrosion spiral steel pipe?

• First of all, the welded mouth and the periphery of no anticorrosion layer should be polished machine grinding neat, to achieve manpower rust removal 3.0 norms, followed by smearing epoxy powder anticorrosion materials.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Next can use heat shrink tape (including radiation crosslinking polyethylene heat shrinkable patching tape, heat shrinkable sleeve, and polyethylene or polypropylene anti-corrosion adhesive tape) according to the flame heating to make it cover to the 3pe anticorrosion spiral steel pipe welded at the wall thickness to do patching. Or the use of electrothermal fusion sleeve to do the welded joints at the external anticorrosion, the welded joints anticorrosion method is the use of pre-buried electric wire sleeve, with the bundling tape to the electrothermal fusion sleeve tightly tethered to the outer casing, followed by plugging in the power supply to gradually increase the temperature to achieve the pre-set time, automatic power-off to complete the mending operation, and finally wait for the casing to be completely cold to uninstall the tape. These two programmes save time and effort, safe and useful.
