Spiral steel pipes are mainly used for water supply engineering, petrochemical industry, chemical, electricity, agricultural irrigation and urban construction. Used for liquid tran
In the anti -corrosion construction of oil and gas pipelines, straight steel pipes are used as common welded pipes, and their surface treatment is crucial. Because the service life
The strength of the spiral tube is generally higher than that of the straight seam welded pipe. It can use a welded pipe with a larger diameter of the billet material, and can also
1. Raw material preparation: The raw material of anticorrosive steel pipes is ordinary steel pipes. It needs to be cut, polished, etc., so that the surface is flat and smooth, whic
The coating of the 3PE anticorrosive steel pipe is the bottom layer and the steel pipe surface contact the epoxy powder anti -corrosion coating. The middle layer is a co -adhesive
3PE anti -corrosion steel pipe is a steel pipe that has a mother material including seamless steel pipes, spiral steel pipes and straight steel pipes that are processed by anticorr
The scar deficiency in the anticorrosive steel pipe is the concave pit in the inside of the steel pipe, similar to the size of soybean grains. Most scars are gray -brown or gray -b
The anticorrosive method of melting epoxy powder: Mainly: static spraying method, thermal spraying method, pumping method, fluidized bed method, rolling coating method, etc. The co
1) According to the method of use, it can be divided into: pipes in the pipeline, pipes outside the pipeline, and universal powder inside and outside the pipeline. Powers are divid
Followed epoxy powder, also known as thermosettic epoxy resin heavy anticorrosive powder, is a solid material that transports and decentralizes the air as the carrier. A uniform co
1. If possible, it can be phosphorusized for galvanized parts, or spray a layer of phosphoryly primer thin first. 2. Or sand sweep on the surface of smooth galvanized parts. 3. Wip
The substrate (rust -proofladed paint) for galvanized parts has epoxy zinc yellow primer (dual components) and epoxy zinc yellow primer. Galvanized parts are non -ferrous metals, a
