Invented in 1980, the marine rubber airbag used for lifting and transporting heavy objects and ship launching is an innovative product with China's independent intellectual property rights. Marine rubber airbags have been widely used in the fields of launching of ships, lifting and transporting caissons, and buoyancy aid in underwater installation projects.
The International Organization for Standardization (IS) officially released ISO 14409: 2011 Ships and marine technology -Ship launching airbags.The standard stipulates the test conditions of marine rubber airbags and test methods such as air tightness test compression test, unit length bearing capacity test, burst test, compression recovery test and so on.
Before the production of marine rubber airbag, the cord material should meet the requirements of international standards. The marine rubber airbags produced by SUNHELM strictly control the quality, and the minimum design standard for high-strength cord layers is higher than the ISO14409 standard.
SUNHELM pays much attention to safety of products , and the burst pressure usually adopts a safety factor of more than 3 times, which exceeds the standard value of the minimum burst pressure set by the international standard that takes 3 times the rated working pressure of the marine rubber airbag.
SUNHELM's marine rubber airbag adopts the latest talcum powder removal process, which has higher air tightness and has become the first choice of customers.
