Niles, Illinois-MFRI Inc. announced 16 Jan that its Perma-Pipe Inc. subsidiary has received additional orders for the company's Autotherm-brand Glass Syntactic Polyurethane (GSPU) thermal insulation system for oil and gas sub-sea flowlines.
Perma-Pipe Inc. has gained four significant orders totaling about $26 million from major and independent multinational oil and gas companies, said the MFRI statement.
Perma-Pipe will apply GSPU insulation to pipelines that will be installed in the Gulf of Mexico. Autotherm is both a thermal insulation process and an automated system for applying the specially formulated PU compounds to the exterior of steel pipes, explains MFRI. These pipes are used in oil and gas flowlines and risers connecting sub-sea wells to their host platforms.
Autotherm is designed to provide reliable insulation properties at cold seawater temperatures and "significant hydrostatic pressures in deep water over the anticipated service life of the sub-sea oil wells," said the MFRI statement.
Such pipelines are installed at depths of up to 10 000 feet (3050 m).
Sub-sea oil flow lines need insulation at these depths to prevent paraffin or hydrate build-up on the internal pipe surface and hence ensure continuous flow, the company explains.
"These orders significantly increase the backlog for our oil and gas pipeline processing facility in New Iberia, Louisiana," said Fati Elgendy, President of Perma- Pipe, in MFRI's statement.
"We anticipate that the requirement for insulated sub-sea infield pipelines in the Gulf of Mexico and elsewhere will continue to be active as oil and gas producing companies tie-in sub-sea producing fields to new and existing platforms", added David Unger, chairman and ceo of MFRI. "
