Pipeline Products are those products which are directly or indirectly associated with pipelines. These products either used to join pipes, support pipes, help in reducing rigidity, reducing and controlling flow etc.

AIR RELEASE VALVES

Air valve function to release air pockets, which collect at each high point of a full-pressured pipeline. Tamper proof air valve can open against internal pressure, because the internal lever mechanism multiplies the float force to be larger then the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve.

PRODUCTS SPECIFICATIONS:

SIZE: 50MM to 200MM(Higher Sizes on Request)

SPECIFICATIONS: General manufacturing standard, IS: 14845

PRESSURE RATING: PN-1.0 to  PN-25 and Class upto #300

APPLICATION: Water; stem Hot water, Oil, Clear Water and sewage

Gate Valves/ Sluice Valves

Gate Valves are used in multiple applications, suitable for bother above and underground applications.

Gate Valves are designed for fully open or closed applications. When operating the valve stem, the gate moves upwards or downwards on the threaded part of the stem.

When gate valve is fully opened , gate valve does not have any obstruction resulting in low pressure loss, and this design makes it possible to use as a cleaning pig.

Gate valve has a both metallic and resilient seat, available in rising and non rising stem type.

Sizes availability is from 25 mm to 2000 mm with pressure rating from PN 1.0 to #900.

Globe Valve

Globe Valve, as name suggests, it is having S shaped fluid passage i.e. spherical in shape. These valves provide excellent sealing to leakage but as compared to gate valve these have greater fluid resistance.

Size, Rating and Material available :- As required

Other Valves such as Butterfly Valves, Check Valves, Safety Valves, Control Valves etc. are readily available.

HDPE sheets are widely used in Hydropower sectors, where pipe movement is required. Reducing friction between Pipe and Concrete Anchor block is the major application for Hydropower Pipeline System.

HDPE or Polyethylene high density is a polyethylene thermoplastics made from petroleum. High Density Polyethylene (HDPE) sheet is extremely strong against impact, abrasion resistant, and exhibits a low coefficient of friction It is famous for high strength to density ratio.

Standard size availability is 2m x 1m

But as per application observed in Hydropower sector, we provide cut size as required.

Flanges are connecting medium for pipes, valves, pumps etc. These are bolted connection to make installation and removal easier for cleaning and maintenance purpose. Flanges are widely used with gaskets, O rings to make it leakage proof. Flanges are available in Flat face, Raised Face, Serrated Face etc. (As required)

Sizes and Material : As specified by you.
