Quick Answer: A chain pipe wrench is a pipe-gripping tool in which a steel chain wraps around the pipe and hooks onto a toothed jaw on the handle. Pulling the handle tightens the chain and turns the pipe, which lets one tool grip large or awkward diameters.
Gripping a Pipe With a Chain
An ordinary pipe wrench is limited by how wide its jaws open. A chain pipe wrench is limited only by the length of the chain, so it can grip large pipes, fittings and round objects that no jaw would fit. The chain is passed around the pipe and hooked back onto the handle’s head; as the handle is pulled, the teeth on the head bite into the pipe and the chain pulls it tight against them. Easing the handle back loosens the grip so the user can take a new bite without unhooking.
Because the chain needs little clearance around the pipe, the tool also works close to walls and between parallel pipes. On many designs the head is toothed on both faces, so the wrench is turned over to change direction. The teeth mark the surface, so it is not used on polished, plated or plastic pipes. For smaller fittings with flats, an adjustable wrench is kinder to the work.
Applications
- Plumbing and pipe-fitting practicals in TVET and ITI courses
- Maintenance of water supply and drainage pipework in lab buildings
- Freeing seized large-diameter threaded fittings
- Turning round components that other wrenches cannot grip

Care & Handling
- Wrap the chain snugly before pulling; a loose chain slips and jerks.
- Do not extend the handle with a pipe or hammer on it.
- Clean dirt from the chain and teeth, oil the chain lightly and check links and pins for wear.
- Support long pipes so they do not swing as they come free.

Frequently Asked Questions
When is a chain pipe wrench better than a standard pipe wrench?
When the pipe is too large for jaw wrenches, when it is in a confined space, or when the object is round and awkward to grip.
Will it damage the pipe?
The teeth bite into the surface and leave marks. Use it on steel or iron pipe, and use strap wrenches or soft jaws on polished, plated or plastic pipe.
How do I change the direction of turning?
On many designs the head has teeth on both faces, so you turn the wrench over and rewrap the chain. Check how your wrench is made.
Why does the chain slip?
It was wrapped loosely or the teeth are clogged or worn. Wrap it snugly, clean the teeth and replace worn parts.
Can it be used on plastic pipes?
It is not recommended. The teeth and chain pressure can crack or deform plastic; use a strap wrench instead.
How should the chain be maintained?
Clean off dirt, oil the chain lightly, and check links and pins for wear or stretching before use.
