High-Pressure Hydraulic Press Large Gap

At present hydraulic test machine's conventional sealing form is confined by sealing ring's material at home and abroad .

The space between sealing gasket sealing surface and the wall of the steel pipe is small, when the steel pipe come in and out of sealing device,it will arise friction loss with sealing gasket, and such Seal forms require remove the weld seam about 150mm long .In order to make the weld seam height consistent with the tube. in order to meet the two issues and to meet the needs of the hydraulic test of pipe manufacturers , the company developed a tube-side steel frame large gap radial seals.

Steel frame large gap seal structure, performance characteristics: 1. Ring is consist of rubber ring apron and framework ,the overall framework is discontinuous ring ,and made of steel . the ring coordinate with steel skeleton organicly . stretching back and forth freely, to seal. 2.

Seal ring fully considered during the reciprocating motion is not high-pressure water knocked over and so on. 3. Simple structure, easy to use and replacement. 4. Aprons with special materials, can hold weld seam out of leakage. 5.

Selection of steel frame to match with nature of the material, to make organic complementary intermittent ring, expansion of this ring is large, easy to lead pipe. 6. Pipe diameter sealed, the steel of the same diameter, do not need to think about the thickness of wall problem, simply prepare a regular ring. 7. Seal installation and removal is easy. 8.

Do not take the friction, The surface of rubber ring basically no consumption , use long, rubber ring is less consumption, save for circle time, productivity is improved.
