Chemical Hose Is Suitable For Dangerous Chemicals
OrientFlex is an expert in PVC layflat hose solutions. Since set up in 2006, we always insists the principle that “Quality determines all”. Therefore, we take all the measures to guarantee the best quality. In another hand, the raw material determines the quality of PVC layflat hose. Thus we import the top-grade raw material from home and abroad to keep the quality from the resource.
Besides raw material, we import advanced equipment from Germany and Japan. All of the machines are of the greatest in the world. What’s more, we set up a professional inspection team. Two inspectors works in the factory all year long. All of the PVC layflat hose will be checked 3 times before delivery. Next let’s see what are the check items.
Appearance
First we look at the hose to make sure the right color according to client’s sample. Then check if there is any colour difference. Next, check the printings to guarantee the words are correct an clear. Last, we check if the inner tube and cover are smooth.
Size and performance
First we check if there is any terrible smell, especially food grade PVC layflat hose. Because it relates to food security and health. Then we check the diameter and wall thickness. While the tolerance should be±0.5mm and±0.1mm accordingly. Hardness is also an important parameter. We use the Shore durometer to test it and make sure the hardness meets the standard.
Next is the weight and length
Test and record the weight according to the contract , then check if the weight and length fit each other. The tolerance of weight should be within±0.25KG.
Pressure and ductility
Test and record the burst pressure and the ductility under the pressure. The burst pressure is at least 3 times of the working pressure. While the ductility should be within 1.5%.
Assembly
The fittings should connected to the hose correctly. Besides, the size and material of fittings should be the same as the contract.
Package
After the tests to hose itself, we check the package. All the factors like box, shipping mark and color card should show the specs clearly and correctly.
It’s precisely because those detailed test, our PVC layflat hose could be famous in the world. In the past 15 years, we have export our PVC layflat hose to over 100 countries and receive good reputations from our clients. Now we are trying to set distributors in the worldwide.
