Increaser with metal head plug of isolation

The increaser with MHPI is a connecting element of pipe-lines of different diameters. The metal head plug of isolation is used for protection from moisture penetration and possible mechanical damage at the work site at temporarily stopped works. It is also installed at the crossing lines of insulated pipes into steel ones.

An example of the type codes in the ordered specification:

Shortened increaser from steel pipe of 630 mm in diameter, with thickness of pipe wall 8 mm, to steel pipe of 426 mm in diameter, with thickness of pipe wall 7 mm, with isolation of type 1 from polyurethane foam, in polyethylene casing, with metal head plug of isolation of 200 mm in length:

• Increaser St630*8-426*7-1-PUF-PEM-200 with MHPI

Shortened increaser from steel pipe of 630 mm in diameter, with thickness of pipe wall 8 mm, to steel pipe of 426 mm in diameter, with thickness of pipe wall 7 mm, with isolation from polyurethane foam, in galvanized casing, with metal head plug of isolation of 200 mm in length:

• Increaser St630*8-426*7-PUF-GalM-200 with MHPI

Notes:

The distance from the pipe end to the metal head plug of isolation is 70 mm – for diameters 219 inclusive, for pipes of all other diameters, it is 110 mm.
