1, measuring the thickness of the wall: to see flexible PVC garden water hoses if the thickness of the wall is reached, here is a point to be paid attention to. Some pipes are empty tubes, the thickness of the two ends reaches the requirement, but the thickness of the middle wall is thin, and the requirements are not reached. At the same time, the cost can be reduced by the way of pumping.
2, volume length: see flexible PVC garden water hoses whether the required length has been achieved, and some manufacturers have reduced the price by shortening the length. Negative deviation is not allowed according to GB/T10002.1-2006.
Two. Look at it
1, look at the gloss: the surface gloss good looks oily is very good quality products.
2, look at the color: the standard high quality PVC-U pipeline is light yellow, if the white flexible PVC garden water hoses that shows calcium powder added excess, some manufacturers, recycled materials add too much, made into pipe black, yellowing.
Weigh: the two hose with the same diameter, wall thickness and length are more weight. The calcium powder and impurities of high weight have been added too much. The material is not pure and can not reach the requirement.
