We are able to supply PVC Van stone Flanges in the range of 50-500 mm manufactured to ISO 4422.2-1996 standards.
We can provide the following products within the range of 20-315 mm manufactured in accordance with the ISO 4422.2-1996 standard. PVC 90 Deg Elbow, PVC 45 Deg Elbow, PVC Coupling, PVC Tee, PVC 4 Way Cross, PVC Reducing Tee, PVC Flange.
The mass of PVC material is only 1/5 of iron, which makes it very easy to handle, load and unload and construct in comparison.
PVC material has good resistance to acid, alkali, and corrosion. The strength of water pressure resistance, external pressure resistance, and impact strength is high. It is especially suitable for the chemical industry, sewage treatment, industrial fluid transportation, swimming pool, etc.
PVC piping system has a smooth surface, low fluid resistance, a high flow rate in the same caliber, and no scale adherence.
Vanstone Flanges plays the role of coupling, compensation displacement. More convenient than a one-piece flange in the maintenance and installation of pipelines.
Please note ：
That the pipe is installed inside the fitting and we measure the outside diameter when measuring the pipe and the inside diameter for the fitting.
