Do Hot-dip Galvanized Steel Pipes Need To Be Painted?

Generally, galvanized pipes do not need to be painted. If they are painted, they are usually painted with silver paint. After the steel pipe is galvanized, the surface is covered with a layer of zinc coating, which isolates the steel pipe from the atmosphere, avoids direct contact and corrosion of the steel pipe by the […]

Protective Measures For Insulated Pipes

In engineering, industry, chemical industry or home, pipe insulation is the most common way, and the closest thing to life is the insulation of heating pipes. Polyurethane direct-buried insulation pipes are used in thermal and cold insulation projects for various indoor and outdoor pipelines, central heating pipelines, central air-conditioning pipelines, chemical industry, medicine and other […]

The Basic Method Of Steel Pipe Derusting

Long-distance oil and gas pipelines are an important means of energy security. During the anti-corrosion construction process of oil (gas) pipelines, the surface treatment of steel pipes is one of the key factors that determine the anti-corrosion service life of the pipelines. It is the prerequisite for whether the anti-corrosion layer and the steel pipe […]

Connection Of Polyurethane Insulated Pipes

Polyurethane insulation pipe, which is the full name of high-density polyethylene plastic outer protective polyurethane foam prefabricated direct-buried insulation pipe, is formed by connecting the working medium pipeline, polyurethane insulation layer and polyethylene plastic outer protective pipe that transports the medium through the equipment. Forming. Polyurethane insulation pipes are widely used. It has the following […]

There Are Many Insulation Methods For Anti-corrosion Steel Pipes

Anti-corrosion steel pipe is a new type of steel pipe, after anti-corrosion treatment, it can effectively prevent or slow down the corrosion of chemical or electrochemical reactions during transportation and use; however, it is an excellent anti-corrosion steel pipe, please pay attention when using it; keep it warm , especially in the cold winter, In […]

Application Of TPEP Anti-corrosion Steel Pipe

TPEP anti-corrosion steel pipe (T, the initial letter of three-layer English Three, PE refers to polyethylene, EP refers to epoxy resin) is based on the outer 3PE inner fusion-bonded epoxy anti-corrosion steel pipe and the outer single-layer polyethylene inner epoxy composite steel pipe. The upgraded product is the steel pipe anti-corrosion form commonly used in […]

Requirements For Anti-corrosion Steel Pipes For Anti-corrosion Coatings

Common anti-corrosion process of anti-corrosion steel pipes Anti-corrosion steel pipes refer to steel pipes that have been processed by anti-corrosion technology, which can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reactions during transportation and use. 3PE ordinary anti-corrosion steel pipe refers to 3-layer structure polyolefin coating (MAPEC) outer anti-corrosion […]

The Function Of Plastic Coated Steel Pipe

The buried pipeline adopts the transmission line iron tower of plastic-coated steel pipe, which is composed of towers connected by tower pole devices. The tower is made of section steel. The steel surface of the tower rod and the inner and outer surfaces of the tower rod are hot-dipped with a modified polyethylene plastic layer. […]
