Description
Houghto-Safe NL1
Industrial Hydraulic Fluid For Direct Riser Tensioner Systems
Houghto-Safe NL1 from Quaker Houghton is a water Glycol fire resistant industrial hydraulic fluid that has been designed to meet the demanding conditions seen in direct acting riser tensioner systems. This is largely due to its high levels of mixed hydrodynamic and boundary lubrication additives and has been validated in long-term OEM cylinder tests. Degradation of hydraulic fluid (evidenced by accelerated reduction in pH) has been observed in some DAT/N-Line systems.
Such degradation includes the formation of sticky, high viscosity, black residues that contain metal fines. Metal fines have been shown to react with organic acidic additives within water glycol fluids – under certain conditions, this can result in the observed black residues. These residues are of concern as they may deposit around sealing elements. It is also of concern that deposits might reach the interiors of anti-recoil valves and cause the system to fail.
Houghto-Safe NL1 has been formulated to minimise such residues and maintain a stable pH over a 5 year period.
In addition to the above, the cylinder bore surface is often uncoated, untreated low-alloy carbon steel that has reduced corrosion and corrosive wear resistance under lower pH conditions.
Main Applications of Houghto-Safe NL1
Houghto-Safe NL1 is a solution for direct acting tensioners and all other motion compensation applications, designed and formulated to reduce and minimise unwanted residues caused by industrial fluid degradation, extending hydraulic system life and reducing operating costs.
