Three oil two cloth anti-corrosion steel pipe, brush oil wrapped anti-corrosion spiral steel pipe manufacturer

Description :

　　Large caliber anti-corrosion spiral steel pipes are mainly used for anti-corrosion of the outer walls of buried or underwater steel oil, gas, water, and heating pipelines. They are also suitable for anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, refinery and chemical plant equipment, as well as waterproofing and leakage prevention of concrete structures such as concrete pipes, sewage tanks, rooftop waterproof layers, bathrooms, basements, etc.

　　Large caliber anti-corrosion spiral steel pipe primer is used for anti-corrosion primer coating on the inner wall of water supply pipelines, and topcoat is used for anti-corrosion topcoat coating on the inner wall of water supply pipelines.

　　Large caliber anti-corrosion spiral pipe refers to a steel pipeline that has been processed through anti-corrosion technology to effectively prevent or mitigate corrosion caused by chemical or electrochemical reactions during transportation and use.

　　Main anti-corrosion processes:

　　1. IPN8710 anti-corrosion (mainly applicable to drinking water pipelines)

　　2. 2PE/3PE anti-corrosion coating epoxy powder, second layer adhesive, third layer polyethylene. Epoxy coal tar asphalt anti-corrosion (formulated with epoxy resin, coal tar asphalt, rust proof pigments, additives, and modified amines. The product has fast drying, good adhesion, good flexibility, two-component packaging, and easy construction. It has the characteristics of acid resistance, alkali resistance, salt resistance, water resistance, oil resistance, etc.).

　　3. Epoxy powder anti-corrosion (using electrostatic spraying technology to apply epoxy powder on the surface of steel pipes, forming a film in one go. This coating has the advantages of easy coating operation, no pollution, good impact and bending resistance, and high temperature resistance).

　　The main implementation standards for FBE epoxy powder anti-corrosion are SY/T0315-1997 steel pipeline fusion bonded epoxy powder coating technology standard, and 2PE/3PE anti-corrosion are SY/T0413-2002 (test) buried steel pipeline polyethylene coating technology standard.

　　Large caliber anti-corrosion spiral steel pipe anti-corrosion medium:

　　There are many types of corrosive media inside large-diameter anti-corrosion spiral steel pipes, including acid, alkali, salt, oxidant, and water vapor. The coating must have chemical inertness, acid and alkali salt corrosion resistance, and the coating should have a dense structure, good waterproof permeability, strong adhesion, toughness, and fullness.

　　Large caliber anti-corrosion spiral steel pipe primer: composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti rust pigment filler, additives, etc., cured at room temperature to form an interpenetrating network, with a dense coating structure, acid, alkali, salt resistance, excellent anti rust performance, and strong adhesion.

　　Large caliber anti-corrosion spiral steel pipe topcoat: composed of epoxy, rubber resin modification, non-toxic anti rust pigment filler, additives, etc. Excellent chemical resistance, non-toxic, and resistant to microbial erosion.

　　Attention should be paid to the storage and construction of large-diameter anti-corrosion spiral steel pipes:

　　1. During construction, it is necessary to check whether groundwater and rainwater have come into contact with the pipeline. If water has come into contact with the pipeline, the pipeline jacket should be dried.

　　2. When installing pipes, they should be handled with care, and collisions and falls should be prohibited.

　　3. The insulation layer of the insulated pipeline must not collide with the burning fire to prevent the insulation layer from being burned off.

　　4. Pipes and fittings should be stored on relatively flat ground, neatly stacked, and the height of stacking should not exceed 1.5 meters.

　　The production process of large-diameter anti-corrosion spiral steel pipe:

　　1. Inspect the anti-corrosion steel pipes and conduct comprehensive inspections based on various conditions to ensure that they meet the requirements for producing insulated steel pipes. Check whether the steel pipe is corroded, and remove the embroidery on the steel pipe.

　　2. Put the rust removed and anti-corrosion steel pipe into a polyethylene sleeve for threading and forming. After the head is repaired, polyurethane foam is injected into it to fully fill the gap. Inspect the anti-corrosion steel pipes and conduct finished product inspection on the completed insulated steel pipes.
