A new pipe, which is laid in the ground as the old one is being removed, can be connected to the flexible tube or to the lead pipe being extracted behind the rear end (in relation to the direction of pull) of the lead pipe.

Rupture of the pipe during extraction is thus avoided.

Drawing rolling of the naked lead pipe is thus carried out using the mandrel mill.

They receive water through a lead pipe connected to the corresponding lift line.

Lead pipe The only well to date was unearthed in the South West of the facility in 2005.

Disclosed is a method of extracting a hollow unit laid in the ground, such as a lead pipe (2) which is accessible at both its open ends.

A pressure transmitter detects the pressure of an object to be measured, such as liquid, slurry, or gas with fluctuation (variation) in pressure, via a lead pipe.

A pressure transmitter detects the pressure of an object to be measured, such as liquid, slurry and gas, which has pressure oscillation, by way of a lead pipe.
