At present, many home decoration options in China are 6 points (25mm diameter, 4.2mm wall thickness). Today, experts from Suzhou, Germany, use this water pipe as an example to tell you how to distinguish the quality of PPR pipes. Nowadays, the building materials "target=_blank> PPR pipelines in the building materials market are full of enthusiasm, which makes consumers unable to purchase good PPR pipelines at an important moment in the decoration, affecting the timely renovation of the home. How consumers should identify PPR The quality of the tube is good or bad. At present, many home decoration options in China are 6 points (25mm diameter, 4.2mm wall thickness). Today, experts from Suzhou, Germany, use this water pipe as an example to tell you how to distinguish PPR. The quality of the tube is good or bad.
when customers want to cut thick thickness more than 20mm , and the budget & space is limited , Portable Flame Cutting Machine is more suitable.
1. portable type Flame Cutting Machine is small size , can save much space and cost .
2. It's more agile,easy to install , easy to move , and small space to put is ok.
3. Flame cutting max cutting thickness can be 300mm , so it's more economice and suitable for thick sheet, it's more economic than Plasma Cutting Machine
4. No thickness limited , any thickness sheet can stand , NO limited loading -bearing .
One: look at the code on the body. By looking at the code on the body, quickly determine whether the brand water pipe is of international high quality. For standard pipe products, there is usually complete coding information on each pipe to help consumers identify. In addition to the brand identity and origin, the good PPR pipeline also includes the application environment and the certification standards of the world's authoritative organizations. Depending on the information on the pipeline, it is even possible to trace production time, batches and even production machines.
Two: See if the body is transparent. The tube is tested for light transmission by LED light to check if it is easy to breed bacteria. Light and oxygen are the two major factors for the survival of bacteria and algae. Therefore, if the pipeline is transparent, it is easy to breed bacteria and algae in the pipeline (the popular "green hair"), which seriously affects the health and safety of domestic water; therefore, the same Under the environment, the poorer the light transmittance, the better the water pipe. According to this principle, we can easily use a LED light to test the light transmission of the tube.
Three: smell the welding smell. High quality pipes should be colorless and odorless when hot melted. The welding of the PPR pipe is joined by hot melt, making it a seamless joint. A poor quality PPR pipe will emit a pungent odor and toxic substances when it is hot melted. In order to ensure the health and safety of daily drinking water, the PPR pipe with excellent quality will not emit an unpleasant smell to people's discomfort even when it is hot melted or even burned.
Four: Look at the copper fittings for plating. Good PPR pipe fittings are not nickel and chrome-plated, and are resistant to dezincification brass to ensure water quality. PPR's accessories wire parts are made of copper, and copper is easy to accelerate the aging of PPR raw materials, so many domestic brands will coat a layer of nickel or chromium isolated from brass. This method will release metal elements and cause secondary pollution to water. It has been eliminated by the European standard 20 years ago. A good PPR pipe should be made of professional anti-dezincification brass material, not nickel-chromium. It has higher corrosion resistance than ordinary brass, and it is also environmentally friendly and environmentally friendly.
Five: Look at the size of the accessories, and the length of the wire. Good fittings have larger internal diameters and longer teeth. If the internal diameter is larger, the water flow will have less resistance in the pipeline and no scale, and the water experience will be better. The longer the teeth, the smaller the spacing, the stronger the connection.
Experts advise: As long as you can grasp the above five points to choose a water pipe, you will be able to help you select a better PPR pipe to ensure the smooth renovation of the home.
