Friction less surface
Maximum Load Capacity
100% Leak Proof
Lead Free and Heavy Metal Free
High Izod Impact Strength
Vinyl has developed 100% metals free uPVC Column Pipe for submersible pumps. Not only is the uPVC compound Lead-Free and Heavy Metal Free, but the Special High Friction Thread developed by Vinyl also avoids the use of metal pin, thus giving Metal-Free Leak-Proof Column Pipe.
This unique orientation technique has been developed in the Research and Development (R&D) Lab of Vinyl. This orientation technique is used during uPVC Column pipe extrusion to get higher drop impact and notch impact strength for the uPVC Column Pipe.
The uPVC pipes undergo a series of process and high temperate before they reach the customers. So, we ensure they reach you stress-free even if it means to take an extra step. But it is to give you trouble-free product. Thus, every drop pipe undergoes an Annealing process where all the materials are aligned to improve the mechanical property and the life of the product.

BI Axial Orientation developed with years of R&D and studying the market demand. Vinyl has introduced the latest technology in High impact uPVC Column threaded pipes, which are popularly known as Column pipe / Riser pipe / Drop Pipe or uPVC Column pipe - Pipes for Submersible pumps and Bore well application.
This is another invention of the R&D Lab of Vinyl. This technique ensures the uPVC column pipes are made thicker at the ‘Threading’ end to compensate the material loss due to thread creation. This technique reduces the consumption of raw materials and at the same time provides more strength to the uPVC column pipes.
Unique thick & thin construction of riser pipes: This innovative technique is for making the bore well pipes thicker at the threading end to compensate for material removal due to thread creation. The residual thickness (t) at the pipe-end after removal of the thread is same as the barrel thickness (t), ensuring the riser pipe strength remains the same. This technique saves on the raw material consumption and at the same time provides much higher strength to the Bore pipes.
High tensile, high-impact uPVC Column Pipes are made with special design formulation. This design makes the pipe capable of handling both the internal hydrostatic pressure as well as the huge vertical tensile load, resulting from the column and pump weight. The special formulation ensures that the threads do not become brittle or get chipped off even after repeated loosening and/or tightening during their lifetime. Special raw materials are used in a very well defined processing technique to make these column pipes.
Vinyl column pipes have a dual functional to perform. On one hand, these pipes have to withstand the hydrostatic pressure of the pump delivery. This pressure is maximum in the first pipe connected to the pump and can run as high as 35 Kg/cm 2. And on the other hand, the top-most pipe has to bear the load of the entire column filled with water along with the weight of the pump. The total load may be close to 2 tons. This dual load application is a unique feature and requires special manufacturing techniques. These techniques are available only with Vinyl Tubes Pvt. Ltd.
