The air bend is to form a bending moment through the one -way contact with the outer roller and the outer wall of the tube billet. The air curve will compress the curved wire. This
Real bend, as the name suggests, is to compact the bend. When the actual curves, the inner and outer roller and the inner and outer wall of the tube blank are compacted. 1) The adv
Regular inspections: regular inspections of galvanized pipes to observe whether the pipeline has corrosion, leakage, and cracking. If the problem is found, repairs or replace it in
Preparation: Before installing a galvanized pipe, first prepare for preparation. This includes checking the tube, pipes, valves, etc. whether it is intact, and prepare the required
The spiral tube is also called a spiral steel pipe or a spiral tube. It is rolled into a tube blanket at the angle of the spiral line (called the forming angle) of the steel or low
The spiral steel pipe is a spiral seam steel pipe made of automatic squeezing with steel roll plates as raw materials, often squeezing and forming, and welded with automatic double
The hot -dip galvanized round tube is a hollow and round cross -section light -shaped thin -walled steel pipe. It is a steel pipe formed by the Q235 steel band or coil as the basic
Large -caliber steel pipes are made of thick plates and hot -rolled plates. The manufacturing method is first classified according to the welding method, and the high -efficiency a
Because metal zinc increases to zinc oxide or zinc oxide, the volume increases by 3 to 5 times, and the white rust is large. As a result, the degree of corrosion of white rust seem
A large amount of white rust may appear on the surface of galvanized parts, but the actual corrosion of the coating is relatively mild. In most cases, the appearance of white rust
When the galvanized parts are tightly accumulated and placed in a humid air, electrochemical corrosion will occur due to the local surface of the plating on the surface of the plat
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
