The broad product portfolio of Mannesmann Line Pipe GmbH also includes HFI-welded plain-end oilfield tubes to API 5CT in the 4 ½" (114.3 mm) to 24" (610.0 mm) size range.
These oilfield tubes – or OCTG products (Oil Country Tubular Goods) – can be either casings or tubings. Their applications include classic oil and gas wells, geothermal wells and water wells, i.e. underground caverns or aquifers.
Our manufacturing program comprises the following API 5CT standard grades
Heat treated (quenched and tempered)
Besides the standard grades, we have developed and supplied other grade variants for these products in response to individual customer needs, such as:
Our plant in Hamm produces tubes in diameters of 12 ¾" (323.9) to 24" (610.0 mm) and has a heat treatment shop for normalizing and quench & temper treatment of the tubes. In addition, a full-body ultrasonic testing facility has been installed downstream of the hydrostatic pipe tester, so as to accommodate in-line non-destructive testing of the heat-treated tubes as specified by the applicable standards.
Our plant in Siegen covers the 4 ½" (114.3 mm) to 16" (406.4 mm) size range. Any necessary heat treatment of these tubes is carried out at the Hamm location.
