Pipe and Valve Bonding

Copper braid products supplies a comprehensive range of pipe bonds and valve bonds for earthing applications. These include earth bonds that fit across flanges using the flange bolts as mounting points to achieve a flange bond and stainless steel / hybrid bonds for marine and Oil & Gas applications to Norwegian petroleum industry NORSOK standard M-503 and Transport Canada TP 127E – Ships Electrical Standards section 4.4.

Pipe and Valve bond conductors are commonly made from round tinned copper braid, 6 sq mm to 16 sq mm, with or without insulation, 10 mm2 Tri-rated green / yellow cable for the bonds as a pre-insulated alternative to copper braid, or stainless steel braid (flat or round) upt to 50 mm2. Our design criteria is to achieve less than 0.1 ohms connection resistance.

Typical connections are M6 (1/4″) / M8 / M10 and M12 (1/2″) but we can also supply special lugs for attaching to flange bolts M16, M20, M26 (1″), M32, M40 and M52 (2″). Larger diameters are available on request. The tags are made of either Brass to EN1652-CW508L-H095 or stainless steel grade 316.

These earth bonds can either be supplied already made up or we can supply a kit including everything you need to make up the bonds on site including, copper braid or tri-rated cable, lugs and crimp tooling.
