What is the first step in producing a 90° bend in low carbon steel pipe?
Mark a line on the pipe at a distance from the centre line.
Put the pipe in the bending machine.
Apply pressure and bend the pipe.
Make sure the correct size former is in the machine.
Why is there a gain in length of one pipe diameter when bends are made?
Because of the elasticity of the metal.
Due to the nominal bore of the pipe.
Because of the pressure applied.
Due to the gain in length of one pipe diameter.
What should be lined up with the centre of the bending machine?
The internal diameter.
The centre line.
The fixed point.
The pipe size.
What is the purpose of taking the bend to about another 5° over the 90°?
To ensure the correct size former is used.
To allow it to 'spring back'.
To apply more pressure.
To adjust the internal diameter.
What is the first step in the process for joining low carbon steel pipe using threaded and screwed joints?
Apply the appropriate jointing compound, hemp or PTFE tape to the pipe threads.
Select the appropriate size and type of fitting for the job.
Wipe clean the threads on the pipe with a cloth to remove any swarf or excess cutting oil/compound.
The pipe and fitting are screwed together, using the correct size stilsons or similar pipe wrench.
Which step involves cleaning the threads on the pipe?
Apply the appropriate jointing compound, hemp or PTFE tape to the pipe threads.
Identify appropriate pipe jointing compound that is relevant to the intended use of the pipework.
