Steps that keep cuts square, lengths accurate and bends clean when preparing pipe.
Accurate measuring and marking is what separates neat, leak-free pipework from frustrating rework. Use this as a revision checklist of good practice when preparing pipe.
- Measure twice and cut once. Confirm the length before cutting, because you can always trim more off but you cannot put it back.
- Allow for the fitting. A pipe pushes into a fitting by a set amount, so include or subtract that engagement length, sometimes called the make-up, when marking your cut.
- Cut square. A square cut lets the pipe seat fully into the fitting and the seal sit evenly; a skewed cut can leak.
- Deburr the ends. Ream the inside and file the outside so there is no sharp burr to cut a seal, snag debris or restrict flow.
- Mark bends from a clear datum. For a bend, measure to the centre or the start of the bend as your method requires, and keep the mark on the correct face so the bend finishes in the right plane.
- Check before committing. Offer the pipe up and check alignment before making the joint permanent.
Careful preparation saves material and time. Confirm specific make-up allowances and bending methods for each material and tool you use.
