To protect power and communication cables laid in railways, highways, subways, municipal construction, and other system fields, when the cables pass through obstacles such as railways, highways, and rivers, cable protection tubes are generally added to the pipelines. At present, the cable protection

1. In the test results of straight seam steel pipes, if a certain item does not meet the requirements of the product standard, the unqualified ones should be picked out, and double the number of samples should be randomly taken from the same batch of straight seam steel pipes, and the unqualified it

1. 3PE anti-corrosion steel pipe has high sealing performance, and long-term operation can greatly save energy, reduce costs and protect the environment.2. Strong corrosion resistance, simple and fast structure, and service life can reach 30-50 years.3. At low temperatures, PE has good corrosion res

Common methods for 3PE anti-corrosion steel pipe anti-corrosion:1. Pipeline anticorrosion generally adopts two main methods of external coating and cathodic protection.2. Although most of the surface of the pipeline is covered by the coating, a slight leak will cause an incredible corrosion rate, an

Coated steel pipes can effectively prevent or slow down the corrosion of steel pipes to extend service life and reduce operating costs pipe. It is widely used in various industrial projects.Product name: Coated Steel PipeSize: 800mmX10mmX12000mmStandard: DIN 30670Application: Fluid Transportation Pr

At present, there are two standards for 3PE anti-corrosion steel pipes, namely GB/T 23257-2009 and GB/T 23257-2017. GB/T 23257-2017 is a new standard, implemented in December 2017. The two standards differ mainly in the following ways:3PE anti-corrosion steel pipe1. The design temperature of the ant

Welding equipment: ZX7-400-3 welding machine is used for root welding; Kumagai ZD-500 multifunctional steel pipeline automatic welding equipment is used for filling and covering.Welding material: Bole φ3.2 E6010 cellulose electrode is used for root welding; Lincoln E81T8-G φ2.0 flux-cored self-shiel

There are roughly four types of spiral pipes according to their uses: spiral pipes for drainage, spiral pipes for dredging, spiral pipes for piling, and spiral pipes for oil and gas.Spiral pipe for drainage: Material of spiral steel pipe for drainage: Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9,

Anticorrosion of the inner wall of large-diameter steel pipes:1. Before processing all steel pipes, the steel plate on the inner wall side of the large-diameter steel pipe shall be de-rusted until the metal is exposed to metallic luster (whitening). It should meet the sa2.5 standard required in GB89

Liquid epoxy coating is a coating system composed of two substances. It is mainly applied on floors and gives off a unique finish compared to traditional coatings because of its distinct chemical composition.Product name: Epoxy Coated PipeSize: 260mmX3mmX12000mmStandard: AWWA C210
