Washpipes

On a drilling rig, the washpipe carries drilling mud into the turning top drive. Deublin’s mechanical-seal washpipes last up to 20 times longer than packing, and a service kit changes the seals in as little as ten minutes.

• The circulating mud lubricates and cools the seal faces – don’t run the top drive dry with the seals fitted.
• The washpipe manual covers assembly, installation and seal changes step by step.
