Expansion Joint Corrugated Pipe
The Expansion joints Material is 0Cr18Ni9,size 298x155,it used in ferroalloy furnace, ferrosilicon furnace, calcium carbide furnac

Pressure ring is the function of pressure tight embrace a electrode copper tile, make the electricity flowing through the copper tile evenly through electrode into the furnace. Pressure ring is composed of two and a half circle, internal water is complex, the cooling water into the inferior vena first, and then along the outer water cooling cavity bottom-up cycle, then enter the circle in the circulation, the final discharge. Outer water cooling cavity is very narrow, the inner ring with wider, pressure ring part close to the flame cooling effect is very good, thus ensure the pressure ring of long service life

Corrugated pipe pressure ring main structure features are: holding device with composed of bellows expansion tank top tight copper tile. By water-cooled cover, water pressure ring, water pressure of corrugated pipe and hydraulic medium. Bellows one-to-one top tight in clamping ring forging copper tile, this is the place where pressure on taper ring is superior, to ensure that each copper tile hold of electrode force equilibrium, and easy to adjust the copper tile of electrode pressure. Therefore, the use of pressure ring can prolong the service life of copper tile. Taper ring cannot do this

This product is used for -arc furnace of conductive copper tile fixed clamping, suitable for high temperature environment. The use of the product to reduce the damage of conductive tube and copper tile, more practical than the traditional taper ring. Our company can according to customer requirements design and manufacture of various types of whole boiler steel plate, stainless steel, brass pressure ring.

Telescopic box is a kind of special structure of the hydraulic cylinder, using corrugated pipe instead of the cylinder of the hydraulic cylinder. When the hydraulic system for pressure, bellows elongation, drive the compression box compression copper tile; From pressure, corrugated pipe stretch back to loosen copper tile by himself. Corrugated pipe sealing good, will not leak
