Appropriate Neoprene liner for offshore riser clamps 1

[Enp12444]

Hi Guys,
I am wondering if you can help me specify a riser clamp neoprene liner that would work effectively in marine environment.

Many thanks Steve appreciate it,

I checked it out and seems great yet I am still wondering if the same compression set requirements apply to the clamp liners?

Any thoughts about the acceptance criteria for seawater absorption & ozone resistance for such application?

Seawater absorption:
- Max 5% volume change
- Reduction in tensile strength max 15%
- Change in hardness max +5/-5 units
- No cracking, crazing, blistering or splitting after immersion

Ozone resistance:
- No cracking or 'other detrimental effects'
