Longitudinally welded steel pipe
Salzgitter Mannesmann Line Pipe (MLP) is a manufacturer of HFI (high frequency
induction) longitudinally welded steel pipe, with over 100 years’ experience in
pipe production.
This includes oil and gas line pipe,
pipe for drinking water and sewage
systems, tubes for machinery and
plant construction, oilfield tubes,
pipe for long-distance heating
systems and structural tubes.
The company manufactures
products in a wide range of steel
grades, with outside diameters of
33.7 to 610mm (1.5" to 24") and
pipe wall thicknesses of 3.6 to
20.6mm (0.14" to 0.812").
The company has also expanded its full range standard programme of coatings
and linings, such as PE, PP, (fibre) cement mortar and epoxy lining (flow coat),
to ensure the highest possible level of pipeline safety against corrosion and
mechanical damage, and to minimise frictional resistance on the inside wall of
gas line pipe, by an epoxy resin coating (fusion bonded epoxy FBE) according
to ISO 21809-2:2007.
The single-layer coating has a maximum thickness of 700µm and is used for
corrosion protection, eg for onshore products. Additional dual-layer coatings
are currently under development, which will be applied for special properties,
for example as ‘FBE rough coating’ for an improved frictional resistance or for
an enhanced abrasive resistance.
A reference production of the single-layer FBE-coating has been manufactured
for E.ON UK. The total length of the coated pipes was approximately 3,000m,
with outer diameter of 219.1mm and 323.9mm, and wall thickness from 8 to
20mm.
