Ship launching airbags Introduction

Ship launching airbags are the current ship launching program with the least cost and risk. It overcomes the shortcomings of fixed track launching and provides convenience for ship repair. At present, it is mostly used for the launch of small and medium-sized ships, and the productivity of shipbuilding and ship repairing in small and medium-sized shipyards is limited. Help companies in the shipbuilding and maritime industries save energy, time, workload and investment.

The Reason named SunHelm Ship Launching Airbag as "Defender", because of high performance in ship launching, Various performance indicators beyond international standard. Protect ship launching safety fully. Safety indicators highest reach 4.5-5 Times than international standard.

SunHelm's ship launching airbag uses a cross-wound process, which can withstand greater impact. We use 100% high-quality natural rubber, which is more durable. The service life is more than 6 years, and other Chinese factories mostly use synthetic rubber.

To exceed the performance of ISO14409 standard

Safety factor is the embodiment of comprehensive performance of ship launching airbag, it is an important factor to ensure the safe launching of ships. The safety factor of ship launching airbags depends on three important factors: material, design and production craft. At present, the safety factor of ship launching airbags from SUNHELM has reached at least 4.5 times in an all-round way, exceeding ISO14409 by 1.5 times.

Excellent bearing capacity performance

Bearing capacity definition: When compress deformation reaches 70%, and the inner pressure reach the rated working pressure,Pe. (Unit:kN/m) The core of bearing capacity is to test the pressure that airbag can bear during compression. The stronger bearing capacity,reflect stronger safety and stability of airbag.

Super high burst pressure

Burst Test Definition: Airbags shall be tested to the minimum burst pressure as specified in table 2. Fill the airbag with water until the airbag burst. The water pressure at the time of bursting shall equal or be more than the value specified in table 2 (ISO14409 Required).

Ship launching airbags in harsh environments

In order to adapt to the harsh climate of Antarctica,SunHelm R&D team upgraded the material and process of the airbag, and cooperated with the Brazilian scientific research station to successfully complete the construction of the scientific research station. So far, the sales network of SunHelm products has covered seven continents in the world.

    Does heaviest airbag mean the best performance?
    After long-term testing and application of airbags, not the heaviest product represents the highest quality performance.The factors that will cause airbag to be much more heavy.

    I The content of natural rubber is insufficient.Use scrap to satisfied the weight of airbag.

    I To achieve performance,the recycled rubber material content is high.(Counterweight Rubber)

    I Fewer tire cord layers, thus increasing the proportion of rubber.

    ·Product will cause short service time.

    ·Tire cord layer exposed.

    ·Low tear resistance.

    ·Affect complete product performance.
