Its flame retardant insulation and noise isolation make it very popular in construction and decoration. As s...

(1) Cost of transportation. Galvanized Z-shaped purlins can be placed on top of each other, so the cost of z-shaped purlins is much lower than that of galvanzied c-shape purlins when transporting the same weight. And stacking z-shaped purlins can save a lot of construction site area (2) Through a simple comparison of the previous mechanical properties, under the same load conditions, based on the ...

When opening and closing, the sealing surface of the valve core and valve seat always come into contact and rub against each other, so the sealing surface is prone to wear. When the gate valve is close, the pressure difference between the front and back of the pipe...
