PPR welding process----T-Mech ppr piping system

1, the connection between the PPR pipe and fitting should be welding. For the metal pipe connection we can use flange connection, but to connect with water applicator must be used with metal insert pipe fittings.

2, We should use professional pipe cutter to cut the pipe, which will guarantee smooth incision. 

3, Be sure to clean up the PPR pipe and fitting welding parts  to prevent sand and dust to damage the joint quality.

4, We should heating the ppr pipe and fittings according to the regulation time when welding the pipe and fittings.

5, Insert the pipe and fittings into identified depth to the welding tools without rotating.
 6, After the completion of the heating, immediately join the pipes and pipe fittings for connection. You can adjust the pipe and fitting in a certain time if you find the position is wrong during the connection.

7. After the connection, we should wait for a cooling time to use the pipe and fittings.  Connected pipes and fittings should be done on the wall or the ground with color paint to mark the location of the pipeline, so that you can avoid damaged by redecorate.

Do PPR pipes resist to acid and alkaline?

Do PPR pipes resist to acid and alkaline?
The acidity and alkaline of our drinking water is expressed in  in pH in chemistry, pH = 7 to neutral, pH < 7 as acidity, pH > 7 is alkaline, One simple method to measure the PH degree of acid and alkali is to use  pH indicator paper. You can test the PH by yourself to experience of drinking water PH value if you have that paper in hand.  

The world health organization did not mention clear standard for the drinking water quality. Our GB5749 drinking water hygiene pH indicator is in 6.5 to 8.5; GB17324 bottled drinking water pH indicator is in 5.0 to 7.0. These indicators and the developed countries, in line with the standard of water can be rest assured to drink.

PP plastics are chemically inert, so Ppr pipe is resistant to general acidic medium.

Due to the chemical inertness of PPR pipe, it has a strong resistance to alcohol, acid, alkali and low boiling point hydrocarbon solvent. At indoor temperature, ppr materials are difficult to be dissolved in most organic solvents. And when in Water-based reagent like acid or alkali, the possibility of environmental stress cracking damage is very small. but when with chlorinated organic compounds, strong oxidizer, liquid hydrocarbon contact, it is easy to cause surface crack or swelling, because nonpolar compounds can be easily absorbed by polypropylene. 

PPR pipes can resist general acidic medium, but not strong acid and strong base. 

Therefore, if ppr pipes are for general residential use, no need to worry about the resistance issue.
 

What are ppr pipes, applications, features, and advantages?

1.What are PPR pipes

PPR pipe means Pipe made of Polypropylene Random Copolymer (Polypropylene Random Copolymer type 3). The raw material of PPR pipe is Polypropylene Random Copolymer (PPR-C). The production of ppr pipe should comply with Din8077/8078 standards. The PPR pipes designed for the distribution of hot and cold water. Generally speaking, PPR pipe includes below application, features, and application.

2. PPR pipes fields of applications

▪  Polypropylene system can be used for the below applications:

▪  Heating pipe for residential and commercial buildings, hospitals

▪  Chilled water networks in air conditioning systems

▪  Industry chemicals transportation

▪  Aggressive fluids transportation

▪  Agricultural and horticultural usage of pipe

▪  rainwater utilization systems networks

▪  swimming pool pipe networks

▪  HVAC and Compressed air installations.

3.PPR pipes Features

▪ PPR pipes plumbing systems have a unique multiple layer design.

▪ PPR pipes are designed as the most hygienic system for the transportation of portable water.

▪ PPR pipe have a long life time over 50 years even in the cold and high temperature and stress pressure sitiation.

▪ PPR pipe provides easy installation as compared to all other piping systems.

▪ PPR pipe is non-corrosive, non-calcifiable and has non-contracting diameter relative to the conventional systems.

▪ PPR Plumbing System has same joints.

▪ Low thermal conductivity of Vectus Systems offers energy efficiency. 

▪ PPR Pipe are Flexible & tough for use in high seismic zones

4.PPR pipe Advantages

Polypropylene Random Copolymer as a new type of pipe material, it has many advantages.

▪ Environment-Friendly

▪ Hygienic and non-toxic

▪ Really long life time

▪ Resistance to stray electrica currents

▪ Easy Workability

▪ Low thermal conductivity
