PP RCT Pipe

PP RCT Pipe 대한민국

PP RCT pipe is a new generation of polypropylene random copolymers with beta crystalline nucleation technology.PP RCT pipes are 50% more pressure resistant at elevated temperatures and can therefore be operated continuously at temperatures up to 90°C. The pressure rating is based on the wall thickness of the PP RCT pipe. The pressure rating depends on the wall thickness of the PP RCT pipe. 100% of the new Borealis raw material is safe for drinking water. With a working life of 50 years at 70°C and 1 MPa, PP RCT pipe is suitable for hot and cold water, plumbing, industrial piping, compressed air, food processing, etc. in commercial high-rise buildings.

Introduction

Product Parameter:

IMPROVED 50% PRESSURE RESISTANCE

ZHSU PP RCT pipe is a next-generation polypropylene random copolymer with a special crystalline structure that increases its pressure rating at high temperatures by 50%. Known as polypropylene random crystalline thermal tubing, its enhanced crystalline structure is formed through a special nucleation process that allows the pipe to operate at high temperatures and pressures.

50 YEARS LIFE AT 70℃ TEMPERATURE

2.PP RCT pipe is designed for continuous operation at temperatures up to 90°C. The pressure rating is based on the wall thickness of the PP RCT pipe. Pressure ratings are based on the wall thickness of PP RCT pipe, with a working life of up to 50 years at 70°C and 1 MPa. PP RCT pipe is suitable for hot and cold water, plumbing, and Hydronics in commercial high-rise buildings, industrial piping, compressed air, food processing, etc.

100% NEW RAW MATERIAL FROM BOREALIS

In order to ensure the safety of potable water application, ZHSU imported 100% new Borealis raw material for PP RCT pipes with a range from 20mm(1/2") to 160mm(6"), which is a stable material that will not be affected during processing and manufacturing.

PP RCT PIPE ADVANTAGES

1: 20% higher flow rate compared with the same pressure grade PPR pipes

2: financial saving of PP RCT pipe, the same pressure grade, wall thickness can be thinner, saved more raw material

3: high-pressure resistance at elevated temperatures

4: 50 years working life at 70℃ temperature under 1 Mpa pressure

5: PP RCT pipes are eco-friendly, and guarantee the safety of water application

APPLICATION

1: Hot and cold potable water piping systems in residential and commercial high-rise buildings, hospitals, hotels

2: Heating, ventilation, and air conditioning system

3: Thermal piping system

4: Industrial piping

5: Food processing

Remarks :

→ The heating time for the PP RCT pipe should comply with the requirement of PP RCT products and be adjusted according to the working temperature.when the working temperature is bellow 5℃,the heating time should be extended by 50%.

→ When the heating was finished, quickly remove the pipe and fitting from the welding tools, join them immediately without turning until the marked welding depth is covered by the bead of PPR from the fittings

→ The joint elements have to be fixed during the specified assembly time, after the cooling period, the fusion joint is ready for use
