Quotation from manufacturer of 3PE anti-corrosion steel pipe and 3PE anti-corrosion spiral steel pipe for buried pipelines

Description :

　　Information: Construction steel prices are mainly on the rise. The average price of 20mm HRB400E rebar in 24 major cities across the country is 4110 yuan/ton, an increase of 15% compared to the previous trading day. 11 cities have seen an increase of 30-60 yuan. It is expected that building materials will be mainly adjusted. In China, three-layer PE has been first applied in the oil and gas system. The Shaanxi Beijing natural gas pipeline and the Kushan pipeline that have been built in China, as well as the nearly 4000 kilometers of the West East Gas Pipeline, which is a national key project, have all adopted a three-layer PE external anti-corrosion coating. In Tianjin, the 67 kilometer high-pressure pipeline from Shaanxi to Tianjin, the 30 kilometer high-pressure natural gas pipeline from the outer ring line, and the 122 kilometer underground gas storage pipeline from Shaanxi to Beijing also use three-layer PE. It has become the development direction of external anti-corrosion coatings for pipelines in the future!

　　Hot rolled coils, partially raised. The price of 4.75mm hot-rolled coil in 24 markets across the country is reported at 4193 yuan/ton, an increase of 12 yuan from the previous trading day. Eleven cities have raised their prices by 30-50 yuan. It is expected that the hot rolling price will be mainly adjusted.

　　Medium thick plate: mainly upward adjustment. The average price of medium thick plates in 23 major cities across the country is 4382 yuan/ton, an increase of 3% compared to the previous trading day. Price increases of 10-20 yuan in 6 cities. It is expected that the medium thick plate market will mainly decline tomorrow. Polyethylene molecular structure has extremely high stability and is resistant to chemical corrosion from natural gas, liquefied gas, artificial coal gas, etc. It does not require secondary anti-corrosion equipment. The chemical substances present in the soil will not have any degradation effect on the pipes. Good flexibility polyethylene pipes are a type of high toughness pipe with a fracture elongation of over 500%.

　　The flexibility of polyethylene pipes makes them easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and lower installation costs. 3PE anti-corrosion steel pipes for gas transmission have excellent impact and earthquake resistance capabilities. Polyethylene has an extremely low low-temperature brittleness temperature and can be safely used within the temperature range of -60 ℃ to 60 ℃. It has strong adaptability to uneven settlement of pipe foundations. During winter construction, due to the good impact resistance of the materials, there will be no brittle cracking of the pipes.
