● Laying heat-insulating cable-type insulation pipe

The laying of electric heating cables in the pipe is to avoid the medium transported by the pipeline affecting the circulation operation of the pipeline due to freezing solidification. The specially-made heating cable is closely attached to the outer wall of the steel pipe laid parallel to it in the pipe material, the medium is heated by the steel pipe using electric heat energy. The size, structure structure of the pipes laid with heating cables are completely the same as those of ordinary thermal insulation pipes. They are mainly used for water transportation petroleum engineering in high cold areas to ensure normal medium transportation under long-term low temperature conditions. This compensation heating method is highly efficient energy-saving.

● Double plastic insulation tube

The double plastic insulation pipe adopts plastic pipes such as polyvinyl chloride, polyethylene modified polypropylene as the core pipe for conveying medium. Products are widely used in petrochemical, urban water supply, heating refrigeration projects. It has the characteristics of non-scaling, strong anti-corrosion, high delivery flow long service life. It completely overcomes the damage of chemical corrosion to the process pipeline, better extends the life of the pipeline.

● PERT pipe insulation tube

PERT tube insulation tube uses PERT tube as the core tube of the transport medium, which can be applied to the central heating project with 95 ℃ as the heat source. It has the characteristics of green environmental protection, strong anticorrosion, high delivery flow, convenient installation maintenance.

● Prefabricated direct buried steam pipe

The steam-water combined transportation pipeline system is composed of directly buried prefabricated insulation steam-water combined transportation pipeline / pipe fitting, control system signal transmission system. It is used to transport steam medium, the temperature does exceed 350 ℃, the pressure does exceed 2.5MPa. For the combined steam water pipeline system, the use of the "steam water combined transmission" pipeline system eliminates the need to build a first steam-water heat exchange station, which saves a lot of engineering investment. The first station of combined production of concentrated soda water heating + high temperature water pipeline composition technology upgrade. The product can also use steam pipes with different structures according to user requirements actual application conditions.
