The steel-wire reinforced PVC pipe primarily uses PVC plastic, embedding spiral steel wire as the reinforcement layer. Hence, this product combines rigidity and flexibility, boasting adequate mechanical properties and rigidity while also possessing excellent flexibility. The inner and outer walls of the hose are transparent, smooth, and bubble-free, making the fluid transfer clearly visible. It is resistant to low concentration acids and alkalis, highly elastic, not prone to aging, and has a long service life. It is also resistant to high pressure, maintaining its form under high-pressure vacuum conditions.
Observe whether the wall thickness of the steel-wire reinforced PVC pipe is uniform. If allowed by the manufacturer, take a sample from the middle. This is mainly to prevent fraudulent practices during production, as uneven wall thickness can lead to easy breakage or bursting during use, significantly shortening the hose's lifespan.
High-quality steel-wire reinforced PVC pipes should be transparent and odorless. The specially processed granules should be crystalline without any impurities. In contrast, low-quality steel-wire reinforced PVC pipes contain mixed impurities, leading to yellowing, opaque walls, and lack of aging resistance.
Under good lighting conditions, inspect the hose walls for bubbles or cindered material.
High-quality steel-wire reinforced PVC pipes have a very faint smell, almost unnoticeable plastic odor, without any irritating odor from petroleum additives. On the other hand, low-quality steel wire hoses have a strong, pungent smell due to the use of a large amount of recycled material and chemical additives. Especially in high-temperature seasons, the odor becomes unbearable.
Cut a section of the steel wire from the steel-wire reinforced PVC pipe and try to break it to see if it is easy to break. High-quality steel wire requires professional tools to cut, ensuring the steel-wire reinforced PVC pipe's durability and tensile strength.
