Rubber Lined U-bolt Filter
Rubber lined u-bolts - anti-vibration - insulating - low friction - Anti-chafe
Normal Rubber temperature range -20C to +110C Used to prevent galvanic corrosion due to the contact of dissimilar metals in the presence of an electrolyte. Also, for the prevention of wear and / or crushing of composite, thin wall or non ferrous pipework. Available in stainless steel and mild steel versions
Light Duty Anti-Vibration U-Bolts - Available in stainless steel and mild steel versions
Light Duty Anti-Vibration U-Bolts - Flame Retardant. Specialised flame retardant rubber. Details of the rubber can be found on the product pages. Available in Stainless steel and mild steel versions
These ubolts have been developed to enable pipes to be securely guided with a minimum of friction so safe-guarding the pipe from expansion & contraction wear due to temperature changes; whilst also reducing the noise & vibration of the pipe.
They are fitted with a gap between the ubolt and the pipe enabling the pipe to expand & contract yet keeping it fully guided in position.
The rubber base pad acts to reduce the noise & vibration of the pipes as they carry their fluid and it is fitted with a PTFE strip to reduce the friction and hence protects the pipe as it expands & contracts. The pad also contains a metal spacer for the U-bolt legs to go through giving strength to the pad, and a firm anchor for fastening the nuts at the required position.
The patented-pending ubolt sleeve is a low friction silicone rubber which rotates around the ubolt to enable the pipe to move unrestricted but be fully guided in position on the supporting framework.
These are a much cheaper and more reliable solution to the conventional rubber lined ubolts which have PTFE bonded to the inside surface of the rubber coated ubolt.
Although Ubolts with the PTFE strip bonded to the rubber profile around the ubolts have been in common use for many years, they are prone to the PTFE separating from the rubber due to the difference in the expansion coefficient of the rubber and the PTFE. This problem is eliminated by Graphskill’s unique solution of a single medium with minimal friction
Light Duty Anti-Vibration U-Bolts - High Temperature - Flame Retardant. Specialised flame retardant rubber. Details of the rubber can be found on the product pages
Anti-Chafe U-bolts. A range of "extended length" u-bolts with a thin silicone rubber sleeve. Ideal in those situation where you need a little protection just to stop the metal of the u-bolt chaffing / rubbing against the supported element
U-Bolts With Convex Base to Minimise Crevice Corrosion
These u-bolts have been designed to be used in a minimum contact water repellent situation to prevent water crevice corrosion similar to the I-Rod u-bolts. The enhanced stainless base plate is convex with a silicone tube shroud. This convex surface provides almost a point contact rather than the line contact with the traditional flat support plate. Water will roll away from the pipe and not leave it standing in a pool of water which therefore minimises corrosion.
The u-bolt can be used as grip or non-grip depending upon the arrangement of the nuts. Either both locked together underneath the convex base plate, for gripping the pipe; or, locked either side of the convex base plate to fix for non-gripping application
