Why are PPR pipes used in different colors?

PPR pipes are available in different colors primarily for identification and differentiation purposes. The use of different colors helps in easily distinguishing between different types of pipes and their designated applications. Here are some reasons why PPR pipes are used in different colors:

Brief Introduction of Pipe Calibrating Method

After the pipe is extruded from the sizing sleeve, the temperature is still very high. In order to ensure the accuracy requirements of pipeline size and shape, as well as good surface work quality, it is necessary to take measures such as cooling and sizing sleeves. The purpose of the calibrating sleeve is to ensure that the outer diameter or inner diameter of the pipeline reaches the specified dimensional tolerance range, and to obtain a good surface after cooling the calibrating sleeve.

Factors affecting the brittleness of PVC pipes

PVC pipes have become popular building materials due to their low cost and durability. Pipes can be used for most drainage, water supply, and ventilation. PVC pipes may become brittle and prone to cracking when left unused for a long time. Next, let's take a look at the factors that affect them.

What is the difference between PE water supply pipe and PE drainage pipe

The PE water supply pipe is used to transport tap water, which usually needs to be pumped from the ground to the ground and transmitted to households. Since the PE water supply pipe needs to bear the working pressure when pumping, the PE water supply pipe is generally divided into five levels according to the pressure, namely 0.6Mpa, 0.8Mpa, 1.0Mpa, 1.25Mpa, 1.6Mpa. They bear 6kg working pressure, 8kg working pressure, 10kg working pressure 12.5 kg working pressure and 16 kg working pressure. The higher the pumping pressure is, the higher the working pressure level of the required PE water supply pipe is.

Matters needing attention in using gas PE pipe

PE pipe is not as hard as steel pipe, so it is easy to be perforated when impacted by hard objects. In order to protect PE pipeline from man-made damage, when laying PE pipeline, red brick and warning belt are usually added above PE pipeline, and then pipeline inspection is strengthened. When the gas PE pipe is constructed in advance or buried in a shallow depth, the gas PE pipe is easy to be cut through during the construction of other supporting pipe networks or roads in the community, resulting in gas leakage. In order to avoid similar incidents, the constructed gas PE should be monitored or constructed behind other supporting pipe networks, and sufficient buried depth should be ensured.

Quality inspection of PE pipe welding is essential

Whether the storage conditions of the electrofusion pipe fittings before welding meet the standards and whether the cooling process after welding is appropriate are all factors that affect the quality of the final welding. In China, the specification and necessary construction technology in these areas lag behind the development and application of PE pipes, thus restricting the popularization and application of PE pipes to a certain extent. Therefore, professional training for engineering and technical personnel and construction personnel is an effective way to make PE pipeline construction move towards a formal and good development. Inspection can take the following methods:

Some tips on PPR water pipes

The nominal outer diameter dn of PPR water pipe fittings refers to the nominal outer diameter of the PPR water pipe connected to the water pipe. There is a requirement for the key wall thickness of PPR water pipes, which requires that it should not be less than the wall thickness of the same PPR water pipe series S pipe. In other words, the wall thickness of the pipe fitting must be greater than or equal to the wall thickness of the pipe.

The production process

Raw material + color masterbatch → mixing → vacuum feeding → raw material drying → single screw extruder → Color line extruder → spiral mold → sizing sleeve → spray vacuum setting box → spray cooling tank → spray code machine → caterpillar tractor → finished product detection and packaging
