Cangzhou Shenlong pipeline professional steel surface treatment, for steel shot blasting, spray painting, pickling (steel structure corrosion and rust removal) and other processing methods have a very high level, whether it is steel plate, profile, or other steel structure parts, can be processed, including export steel project packaging, shot blasting spray painting. Heavy anti-corrosion pipe, cement pipe, buried pipe in waterworks, and other services, followed I will tell you about the type and design of anti-corrosion steel pipe

Anticorrosive steel tubes are divided into two categories: surface anticorrosive steel tubes and inner anticorrosive steel tubes.

Three layers of PE anti-corrosion steel pipe refer to the first layer of anti-rust coating, the second layer of adhesive, the third layer of high-pressure polyethylene three raw materials integrated, and seamless steel pipe solid fusion to produce an excellent anti-corrosion layer.

Anti-corrosion design outside pipeline:

Petroleum asphalt anticorrosive coating is the oldest anticorrosive coating, which is used well in most dry areas. With the development of technology, epoxy coal pitch and zinc-rich coating have replaced petroleum pitch as anti-corrosion coatings for steel water pipelines. Due to its excellent anti-corrosion performance and low price, epoxy coal pitch series coatings have always been the first choice of anti-corrosion coatings for steel water pipelines.

The temperature of the conveying medium is generally not more than 110℃. In order to meet the requirements of different corrosion environments for the anticorrosion layer, the anticorrosion layer is divided into three grades: ordinary grade strengthened grade, and special strengthened grade. The structure of ordinary grade is one primer and three coats, dry film thickness ≥0.3mm; The structure of strengthening grade is primer → topcoat → topcoat, glass cloth, topcoat → topcoat, dry film thickness ≥0.4mm; The structure of the special strengthening grade is primer → finish coat → finish coat, glass cloth, finish coat → finish coat, glass cloth, finish coat → finish coat, dry film thickness ≥0.6mm, finish coat, glass cloth, finish coat should be applied continuously. In actual engineering, grade selection should be carried out according to engineering conditions and conveying medium.

The environment temperature should be higher than 5℃ and the air humidity should be lower than 80% when the anti-corrosion layer is constructed. The diluent ratio is 5%, the glass cloth blank holder is 20 ~ 25mm, and the fabric lap length is 100 ~ 150mm. Anti-corrosion layer voltage inspection: ordinary class 2000V; Strengthen the level of 2500 v; Extra booster 3000V. Insulating layer check: using 5 9:10km leak reference, use low-voltage audio signal leak detector.
