Prefabricated insulating pipes are divided according to the structure of insulating layer
Normal temperature polyurethane direct buried insulation pipe, low temperature polyurethane direct buried insulation pipe, cryogenic polyurethane direct buried insulation pipe;
According to the difference of the outer protective layer, it can be divided into: FRP outer protective layer polyurethane direct-buried insulating pipe, degree polyethylene outer protective layer polyurethane direct-buried insulating pipe, steel outer protective layer polyurethane direct-buried insulating pipe and other external protective layer direct-buried insulating pipe.
According to the different delivery media, there are many kinds: polyurethane prefabricated insulation pipes for water supply, low temperature resistant polyurethane insulation pipes, steam-buried polyurethane composite prefabricated insulation pipes for steam delivery, buried rigid polyurethane foam plastic anti-corrosion insulation pipes for petroleum, and so on. There are many other names such as polyurethane buried pipe, polyurethane prefabricated pipe, polyurethane directly buried prefabricated pipe, polyurethane jacket pipe, polyurethane foamed insulation pipe and so on.
Single type: suitable for heating medium below 150X2, of which the ordinary type is suitable for heating medium below 120C, and the low-temperature type is suitable for heating medium between 120 and 150 C (recommended operating temperature below 140 to 2). The thermal insulation layer of this kind of insulating pipe is composed of a single thermal insulation material, rigid polyurethane foam, and the outer thermal insulation layer maintains the shell.
Compound type: suitable for low temperature heating medium. The insulation layer of this kind of insulation pipe is composed of two kinds of insulation materials. Insulation layer, maintenance shell of insulation layer and task steel pipe through heat medium can not be bonded together firmly. The inner layer is a new type of low temperature and thermal insulation material, such as centrifugal glass wool felt, composite silicate and glass foam, and the outer layer is made of polyurethane rigid foam plastics.
Degree polyethylene plastic (commonly known as jacket) maintenance shell. Glass fiber reinforced unsaturated polyester resin plastic (commonly known as FRP) maintenance shell. Maintenance shells with other data, such as spirally welded steel pipe, straight welded steel pipe, bellows, etc. Prefabricated insulating pipes on site: This product is to save the cost of heating pipelines, in the 1990s came into being as the times require a simple direct buried heating pipeline. The steel pipe is transported to the construction site to stop foaming and heat preservation, and winding the FRP maintenance shell after heat preservation.
