Which is stronger 304 or 316 stainless steel
The main component of PVC hose is polyvinyl chloride. It is bright, corrosion resistant, strong and durable. In the production process, there will be toxic auxiliary materials such as plasticizers and anti-aging agent. Therefore, it is not suitable to deliver food and medicine. A high quality PVC pipe is really important to us. It not only concerns the cost, but also refers to the safety. Then how can we distinguish the quality of PVC hoses?
Orientflex tells you how to identify the quality of PVC hose
First, you can look at whiteness and gloss. If it uses too many recycled materials in the production process, the pipes will become black and yellow. And it will affect the quality and property of the plastic pipe. So we can judge if it is of good quality by looking at it.
Second, you can observe its thickness. According to the pipe diameter rules, check if the wall of the PVC pipe wall is even.
Then, the sample can be dropped. If the product we use has high quality requirements, we can hit the PVC pipe hard to check the toughness of the PVC pipe. Fragile PVC hoses are generally high calcium products.
Finally, you can look at its weather resistance. The most direct way is to place the PVC pipe in a high temp and high light place for a few days. Then observe the rate of change of the surface. The smaller the surface change, the stronger the weather resistance and the better the quality.
Above are three methods to install a PP spiral hose guard and hope those can help you. Orientflex is an experienced manufacturer of flexible hoses and couplings.
