Brief introduction:

Pneumatice rubber fender is an internationally popular anti-collision buffer product for ship. It uses compressed air as buffer medium to soften the ship's collision with dock or another ship. Compared with normal spring rubber fenders (such as used tyre fender and solid core rubber fender), it has advantages of large shocking energy absorption, low unit area pressure reacting on ship, excellent impact-fatigue resistance, simple and easy installation and so on. It is widely used on large oil tankers, liquefied gas carriers, ocean platforms, large docks, sea submersible wharfs, etc.  

GB/T 21482-2008 standard:

The standard was issued on March 3rd, 2008 and implemented on September 1st, 2008. The standard mainly stipulates materials, size, technological requirements, test method, inspection rules and marks of marine pneumatic rubber fender.
