Flowline Alaska - Welding, Insulation, Corrosion Coating, for Oil Companies

ince 1981, pipeline insulation has been Flowline's primary line of work. During the last 17 years we have insulated over 2,000 miles of pipe, with most insulated pipe being installed in the oil fields of Prudhoe Bay. In addition to straight run pipe Flowline insulates pipe fittings, fabricated spool pieces and pipeline anchors. Carbon steel, stainless steel, galvanized steel, ductile iron, HDPE, PVC, ABS, copper piping and associated fittings are some of the materials processed through the insulation plant. Flowline's facility was designed to insulate pipe ranging in lengths up to 80 feet and 60 inches in diameter. During large production runs Flowline will routinely insulate up to 10,000 lineal feet of double, triple, and quadruple random lengths of steel pipe per shift.

The polyurethane insulation used is a plural component system which is purchased in railcar quantities, and stored on site in one of six 17,500 gallon heated bulk tanks. Densities ranging from 2.25 to 4.5 pounds per cubic foot can be achieved using our specially designed urethane insulation system. Flowline Alaska operates the best equipped urethane insulation testing laboratory in Alaska. A comprehensive quality assurance program was developed to ensure the urethane insulation system will statistically exceed design requirements 99.99% of the time. We staff a full time Quality Assurance Manager and lab technician to insure product quality.

Jacketing systems utilized by our insulated pipe are typically one of the following: 24 gauge galvanized steel, 16 gauge 3004-H34 Alclad Aluminum, Polyethylene coated 24 gauge galvanized steel, or high density polyethylene. Flowline produces all metal jacketing on a custom roll forming machine during the insulation process. HDPE jacketing is purchased pre-formed and shipped from the Lower 48. Based upon specification requirements Flowline has the capability to apply any one of these jacketing types.

Electrical heat trace channels in galvanized steel, stainless steel, or ABS plastic can be installed on the pipe surface prior to insulation. Additionally, larger glycol or hot water heat trace channel can be installed. Multiple channel installations are also available.

Field joints or weld packs are available in either pre-formed half shell or pour in place urethane systems. Jacketing in these systems may be galvanized steel wraps, aluminum couplings bands, or heat shrink sleeves.
