TCP/RTP Pipe Extrusion Line

Our RTP/TCP pipe production line can produce pipe size range from Ø50-630mm. The RTP (thermoplastic reinforced pipe)/TCP (thermoplastic composite pipe) is mainly used as high pressure and non-metallic pipes use for oil and gas industries. However, it can also be used for water supply and district heating. By changing the inner layer material, the RTP/TCP pipe can working under different temperature and circumstance. Also, by changing number of reinforced machine and reinforced material, RTP/TCP will have different working pressure.

Advantage of RTP/TCP Pipe

  • Compared with steel pipe, RTP/TCP pipe has lower cost under same pressure level.
  • RTP/TCP pipe is flexible and can coiled in roll, which means long length to reduce installation and transportation cost compared with steel pipe.
  • Small flow resistance, good wear resistance and corrosion resistance compared with steel pipe.
  • RTP/TCP pipe can work under very high pressure which pure plastic pipes can not.
  • Under same pressure level, RTP/TCP pipe has lower cost compared with PO pipes.
  • By changing the plastic material and reinforced material, RTP/TCP pipe will have different pressure level and can work in different conditions.

Technical parameter for RTP/TCP pipe extrusion line (for reference only, can be customized):

Single Screw Extruder

Usually, there are two extruders: one for liner layer, one for coverage layer. Based on pipe structures, we will choose different quantities of extruders (for example, additional extruders for glue layer). According to different material, we will choose different screw and barrel.

Liner Layer Die Head

This die head is used to extrude liner layer. It can be in single layer or multilayer according to the pipe structure. Also, its flow channel may change according to different material.

Vacuum Tank

Vacuum tank is used to shape and cool liner layer to form core pipe. We use double-chamber structure. First chamber is in short length, to ensure very strong cooling and vacuum function. As calibrator is placed in the front of first chamber and pipe shape is formed mainly by calibrator, this design can ensure quick and better forming and cooling of the core pipe.

Haul-off Unit

Haul-off unit provides sufficient traction force to pull pipe stably. When forming core pipe, need to have one haul-off unit. After wrapping the reinforced layer and covering the outer layer to form RTP/TCP pipe, need to have another haul-off unit. Two haul-off units should have same speed.

UD Tape Wrapping Machine

This machine is used to wrapping UD tapes on the liner core pipe. Usually, adopt double-numbered winding machines to ensure that the tapes are cross-distributed. The UD tapes can be in different materials such as fiberglass tape, aramid tape, carbon fiber tape, basalt tape, etc. According to different types of UD tapes and different pipe pressure requirements, number of UD tape wrapping machine will change.

Coverage Layer Die Head

This die head is used to extrude coverage layer. It can be in single layer or multilayer according to the pipe structure. Also, its flow channel may change according to different material. Special design which will make coverage layer attach more tightly on the reinforcement layer.

Cooling Tank

Cooling tank will cool the coverage layer to form whole RTP pipe.

Cutter

Cutter controlled by Siemens PLC, working together with haul off unit to have precise cutting. Customer can set the length of pipe they want to cut. Multi-feed-in actions for the accomplishment of one cutting process (protect blades and saws, prevent from blade and saws stuck for thick pipe and cut face of pipe is smooth).

Coiler

According to different types of UD tape used for RTP/TCP pipe, we will customize our coiler to make sure the fiber material inside tape will not be damaged during coiling process. As RTP/TCP pipe normally will be coiled in long length (to save transporation and installation cost), we will make coiler in large diameter.
