Case Study Details

One of the plastic pipes feeding the aggregate wash plant in the quarry had become pierced, resulting in a jet of highly pressurised water shooting out of a pinhole leak.

The quarry needed to carry out a repair to keep downtime to a minimum. To replace the damaged section of pipe would have been extremely disruptive to operations on the site.

Pierced plastic pipe prior to undergoing repair

Sylmasta supplied the quarry with a SylWrap Standard Pipe Repair Kit. The Standard Kit enables any user to fix a leaking pipe where water pressure can be turned off.

Superfast Copper Epoxy Putty Stick was used to seal the pinhole in the plastic pipe. The epoxy putty is supplied in a pre-formatted stick which is kneaded by hand and pushed into the hole whilst soft.

Following the application of the epoxy putty, the pipe was then wrapped with a SylWrap HD Pipe Repair Bandage SYL633HD for pipe diameters 150mm to 300mm.

SylWrap HD is a composite repair wrap with a water-activated resin which sets rock hard in minutes, providing an impact resistant layer of protection to pipework.

When used in conjunction with Superfast Copper, SylWrap HD creates a reinforced repair with pressure resistance up to 30 bar, more than enough to withstand the pressure that the plastic pipe operated under.

With pipe failures at quarries being a frequent occurrence due to the abrasive nature of the contents of slurry being moved around, Sylmasta have since recommended that the quarry take stock of the SylWrap Pipe Repair Contractor Case.

Each Case contains enough products to make up to six emergency live leak repairs in under 30 minutes. The Case is easy-to-store on-site, meaning that next time pipework at the quarry is damaged, all the materials needed are at hand for an immediate repair.
