Although chemical cleaning can make the appearance reach a certain degree of cleanliness and roughness, but its anchor lines are shallow and easily pollute the situation.
Damage welding is to put two plastic-coated pipes directly in the non-destructive welding parts, and it can be directly welded by electric welding. The auxiliary of sealing ring and glue is required. Welding is quite suitable for underground transportation of water media. Connection with construction plumbing.
The connection of branch pipes should be connected with grooved special pipe fittings. If the base pipe of the plastic-coated water supply pipeline is a longitudinally welded steel pipe, it should meet the requirements for the base pipe; if the base pipe is spiral, the production capacity will be reduced, so other steel companies will have no reason to de-capacity.
Spiral steel pipes have greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high steel grade thick-walled pipes, especially small and medium-diameter thick-walled pipes. The main technological characteristics of other spiral steel pipes: during the forming process, The deformation of the steel plate is uniform, the residual stress is small, and the surface is not scratched.
The complete steel pipe layer is the main pressure-bearing layer of the pipe body, so the pressure-bearing capacity of the pipe is not affected by changes in the properties of the plastic layer. Plastic-coated steel pipe is a material coated with PE coating on the inside and outside.
It is an environmentally friendly material and will not cause any impact on the environment during use.
Pickling: Chemical and electrolysis are generally used for pickling. Pipeline anticorrosion only uses chemical pickling, which can remove oxide scale, rust, and old coatings. Sometimes it can be used as a re-disposal after sandblasting and rust removal.
How to weld the inside and outside of the plastic-coated steel pipe is suitable for petroleum, chemical, electric power, metallurgy, transportation, food, gas tanks, pipelines, storage tanks and other equipment and facilities, steel structures and concrete surfaces as long-term anti-corrosion coatings, and can also be used as Anti-corrosion coatings for the inner and outer walls of buried pipelines and cooling towers.
Cyanide anticorrosive coating is aromatic polyurethane, it has superior chemical resistance, heat resistance and radiation resistance, good physical and mechanical properties of the coating film, high strength, wear resistance and gloss, excellent corrosion resistance, oil resistance, alkali resistance, Acid-resistant, salt-resistant, industrial exhaust gas, mainly used for anti-corrosion of concrete surfaces, chemical equipment, pipelines, oil tanks, sluices, dams, docks, mines and other facilities or equipment.
If there are any corrosive things, different steel materials should be placed separately. Plastic-coated steel pipe is a material with many advantages, so it is widely used.
This material will be used in many places, and people's lives are inseparable from the use of this material.
