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 […]
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 […]
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 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. […]
Epoxy powder coating is applied by electrostatic spraying process, forming a film at one time. This epoxy powder coating is a kind of thermosetting coating, which is processed by mixing and destroying solid epoxy resin, curing agent and various additives. The steel pipe is preheated by shot blasting and intermediate frequency before painting, and then […]
After the surface is mechanically damaged, the anti-corrosion spiral steel pipe must be repaired. When the scratches do not cause leakage, the two circular fillet welds between the casing and the steel pipe body do not need to be welded. If it leaks, it needs to be welded. The sleeve is directly subjected to the […]
The quality requirements of galvanized square tubes are very high. However, due to the inevitable corresponding quality defects in each process of steel pipe production, and some steel pipes are in service under some special environmental conditions, in addition to the overall performance of the steel pipe, the accuracy of the outer diameter and wall […]
Common problems can be roughly divided into three types, which are uneven coating, dripping of preservatives, and foaming of preservatives. 1. Uneven coating. The fundamental manifestation of this kind of problem is that the preservative is unevenly distributed on the surface of the steel pipe. Some parts are too thickly coated, while some parts are […]
Galvanized steel strip is processed by ordinary steel strip pickling, galvanizing, packaging and other processes. It is widely used because of its good anti-corrosion performance. It is mainly used to make metal products that are cold-worked and no longer galvanized. For example: metal products such as light steel keels, peach-shaped columns for guardrails, sinks, rolling […]
In order to prolong the service life of pipelines, pipeline anti-corrosion construction has become an indispensable process in the pipeline production process; with the continuous development and production of manufacturers, various types of anti-corrosion spiral steel pipes have appeared on the market. The more common anti-corrosion types of spiral steel pipes on the market are: […]
