Drag reduction in pipeline
Pipe line flow are classified as Laminar and Turbulent
Turbulent Flow require high Energy and Pressure
DRA inclusion in the system transforms the turbulent to laminar flow thus increases the flow rate

Abka international is group of companies, with its own unique growth factor, involved in the manufacturing of polypropylene woven floor mats, polyethylene film / bag,
Un-plasticized polyvinyl chloride leisure furniture for outdoor use and upvc-pipe and fittings conforming to astmd-2466 requirements. The group has the honour of being the largest manufacturer of polypropylene woven floor mats in pakistan and the only producer of unique outdoor & patio furniture in asia. Its sister concern namely
Vincraft (pvt) ltd., is iso-9001:2000 certified and has been presented with
Best trade name award in paris, france. We take pride in the fact that our group in a very short span of time has successfully implemented projects of various natures, including a state of the art pharmaceutical unit to be commissioned very soon. This has been made possible because of the inherent organizational flexibility and versatility of the group; enabling it to simultaneously undertake projects of different types. The factories are located in gadoon amazai, peshawar and risalpur industrial estates of nwfp (north west frontier province). All the companies are member of sarhad chamber of commerce & industry, peshawar nwfp. We intend to maintain and improve our high quality of production to grow globally in future.
We take this opportunity to introduce national plastics as a global technology leader and innovator in piping systems based in sharjah, uae with foot prints in europe, north and latin america, the middle east, asia, australia and africa. In piping systems around the world, specifiers, contractors, pipe-fitter, plumbers and fabricators choose our professional grade products for their proven superior reliability, innovative features and performance, which save time and offer unmatched guarantee of first-time right and longer service life
An elbow provides a change in material flow direction. This adds pressure losses to the system due to impact, friction, and re-acceleration. As the product enters the inlet of the elbow, it typically continues moving straight ahead to the first impact zone. The product is then deflected at an angle toward the outlet of the elbow. The deflection angle is determined by the elbow design the productâ??s characteristics, the conveying velocity, and specific load.

A reducer is a component in a pipeline that reduces the pipe size from a larger to a smaller bore (inner diameter). The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. There are two main types of reducer: concentric and eccentric reducers.
Concentric Reducers: The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1â?³ pipe transitions into a 3/4â?³ pipe and the top or bottom of the pipe doesnâ??t need to remain level. Unlike eccentric reducers, concentric reducers have a common centerline.
Eccentric Reducer: An eccentric reducer is a fitting used in piping systems between two pipes of different diameters. They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where the flow is coming from) is larger than the downstream side
Tee is a forged fitting used for splitting and changing the flow direction of the run pipe. Tee can be manufactured with butt weld extremities, socket extremities or threaded extremities. Tees are in two types:
Equal Tee: The primary purpose of a Tee is to make a 90�° branch from the main run of pipe. â?¦ The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe.
Reducing Tee: The reducing tee is used as the branch has a smaller diameter as the run-pipe.
