The amount of energy absorbed is the main technical performance indicators fender instruments. With the ship's tonnage growth, berthing operations, ship collision energy contact quay or other ships also doubled. Huge collision energy must rely on the contact area on the fender and enough to absorb sufficient deformation. Our ship fender use compressed air as the buffer medium to absorb ship impact energy and have good elasticity. (4)Floating performance is good, not subject to tidal influence, fender can be maintained in the ideal level Pneumatic fenders floating on the water surface (more than 50% of the volume), along with the change of position is not relative to the tidal fluctuation. Especially the ship as the waves rolling, cylindrical inflatable fenders with rolling, the friction force is very small. So it will not damage the coating surface of the hull, and also decrease the moving. Look to LianJiu for a Ball Valve selection that can handle pressures up to 700 bars and temperatures to 400°F. As a type of quarter-turn valve, ball valves can shut off liquid flow from a pipe. An attached lever helps allow a spherical port to reopen flow and shut it off again. By selecting your ball valve according to how the casing around the ball is manufactured and assembled, you can direct flows in multiple directions, such as with a three-way ball valve. You also can accommodate consistently high-pressure applications with a trunnion ball valve with durable anchor points around the ball. Shop Grainger today.

2.Product description:
Penumatic rubber fender with chain protection
(1) High energy absorption
(2) Ultra low back pressure
The inside air of  pneumatic fenders is low pressure gas, the internal pressure increase is very limited during compression deformation. Due to the large contact area, unit pressure acting on the ship hull surface is very low, compared with other fender instruments, is not the common low back pressure.
(3) Inclined contact, good adaptability
Ship must have certain angle which have the possibility of contacting the side of the shore. As the inclined interface of sea inflatable fender, its adaptability is much higher than other fender.
