hi all
need some help about the pipe that needs to be bent

1st is there any builders in or around portsmouth

if not

2nd what methods have been used to stop if from kinking

thanks

Pack it tight with sand...

You should be fine with a set of plumbers tube benders, they support both inside and outside of the tube, might take a bit of elbow grease mind

By some scrap bends, cut and weld

Buy a pipe bender?

Be careful to discriminate between tube and pipe. Tube is thinwall and cannot be bent using a pipe bender. Pipe such as waterpipe has a much thicker wall and may be bent with a hydraulic bender using the appropriate formers.

Tube may be bent in a variety of ways most of which were covered in depth if you search on this site for "Bending Tubes".
