This line , which can also be used for finishing smaller diameter casing , consists of two double numerically controlled threading machines followed by a couoling make-up machine . the finished pipe goes to the hydrostatic test bench (where test pressures up to 1250 bars can be applied) and is then drift tested . this is followed by automatic weighing, measuring and marking operations. Threads are lubricated with a special compound andprotectors fitted.
A transparent protective varnish is applied to the pipe , which is then automatically bundled in hexagonal lifts.
