Plastic coated steel pipe inside and outside

Plastic coated steel pipe inside and outside Both the inner and outer walls of the plastic coated steel pipe are coated with epoxy resin, the surface is smooth, the fluid resistance is reduced, the flow rate is increased, no scale is formed, and microorganisms generally do not grow. The service life of the fire-fighting water (gas) pipeline is greatly improved through the plastic coating treatment of the water delivery, buried pipe, acid, alkali, and salt corrosion of the fire-fighting water (gas) pipeline. The service life can reach more than 50 years. The pressure range of the fire pipeline is 0-2.5mp. Fire-fighting plastic-coated steel pipes are based on steel pipes. The exterior wall adopts thermosetting powder coating, which has high adhesion, impact resistance, corrosion resistance, and weather resistance. The inner wall adopts thermoplastic powder coating with high adhesion, corrosion resistance, and food-grade hygiene. The inner and outer plastic coated composite steel pipes for water supply are manufactured by sandblasting chemical double pretreatment, preheating, inner and outer plastic coating, curing, post-treatment, and other processes. It a cost-effective product upgrades from the traditional steel-plastic pipe and galvanized pipe. The product has passed the national solid fire extinguishing system professional certification and the refractory component quality inspection center. Post time: Sep-16-2020
