PVC Suction Tube is a special PVC pipe used for fluid suction and transportation. It combines the general characteristics of PVC material with the special design of suction working conditions.
Key features of PVC Suction Tube
Firstly, Goodchemical corrosion resistance
PVC has excellent resistance to acid, alkali, salt and a variety of organic solvents (such as hydrochloric acid, sulfuric acid, sodium hydroxide solution).
Secondly, Good temperature resistance
Working temperature is-10℃ to +65℃.
Thirdly, Fluid efficiency and physical properties
The inner wall is smooth and the friction resistance is small, which reduces the energy consumption of fluid transport and reduces the risk of blockage. High pressure resistance, good flexibility, small bending radius.
Fourthly, Safety and environmental attributes
Good flame retardant, self-extinguish when separated from fire.
Attention: Some soft PVC contain phthalate and other plasticizers, which may seep out and contaminate the fluid (especially contact with high temperature liquid).
Typical application scenarios
Industrial fluid treatment: chemical corrosive medium (acid, alkali) suction, electroplating solution transportation.
Building drainage/sewage: sewer pipes, rainwater collection system, low cost and corrosion resistant.
Medical and laboratory: used for suction tube and liquid guide tube (strictly select products without phthalate).
Agricultural irrigation/drainage: light and easy to install, suitable for water and fertilizer delivery, greenhouse drainage.
Notice
- Temperature limit
In low temperature environment (<-10°C), ordinary PVC is brittle, so it is necessary to select cold-resistant modified formula.
- Chemical compatibility verification
Although resistant to corrosion, it may dissolve or swell when exposed to aromatic hydrocarbons, chlorinated hydrocarbons, ketone solvents (such as acetone, xylene). When conveying food/drug fluids, food grade plasticizer free PVC (in accordance with FDA/ISO standards) should be selected.
- Installation and maintenance points
Avoid violent bending: hard PVC bending should be used with special elbows to prevent rupture.
PVC Suction Tube has outstanding advantages in cost performance and corrosion resistance, but we need choose the right type according to our own needs.
