Products

For over two decades, Crux Products have been designing, fabricating and supplying an array of innovative products for the offshore oil and gas and wind energy sectors.

Crux Seals

Grout Seals The Crux Grout Seal is a passive grout support system for post-installed pile and requires no activation. The action of pile installation through the Grout Seal sets up hoop tension in the reinforced bulbous ring, which can then support the column of grout. More information  Download data sheet

Crux Diaphragms

We design, fabricate and supply a wide range of diaphragm closures for both buoyancy and mud exclusion purposes. Diaphragms are individually designed and pressure tested to meet site specific requirements.

Heavy Duty Diaphragm Closures Crux Heavy Duty Diaphragm Closures are used to provide auxiliary buoyancy and are made from rubber with fabric reinforcement. The diaphragms are held in place by machined flanges. Our product commands the largest share of the worldwide Oil & Gas market. More information  Download data sheet

Mud-Exclusion Diaphragms Crux Mud-Exclusion Diaphragms are used to prevent seabed material from entering the annulus between the pile and pile sleeve or structure leg prior to pile insertion. These diaphragms are used in conjunction with Grout Seals in soft seabed conditions. More information  Download data sheet

Fully Removable Diaphragms Crux Fully Removable Diaphragm Closures is a highly innovative product where all remnants of diaphragm rubber are required to be removed in order to assist with further operations. These diaphragms are supplied pre-fitted in cans. More information  Download data sheet

Rip-Out Diaphragms In certain circumstances Crux Rip-Out Diaphragms may be specified. These buoyancy diaphragms have an integral cutting tool attached which pierces the diaphragm when activated by means of wire rope rigging from the surface. More information  Download data sheet

Reusable End Closures The Reusable End Closure is used to close ends of tubulars for buoyancy purposes. One or more radially expanding seals are seated within a core element and are activated by hydraulic or pneumatic pressure which closes the annulus. More information  Download data sheet
