The article discusses submarine pipeline ball valves. It explains that ball valves use a hollow, perforated ball to control flow, opening when the ball's hole is aligned with flow and closing when pivoted 90 degrees. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of use. The article outlines technical features of ball valves like withstanding high pressures and temperatures, applicable standards, design requirements, testing criteria, and more.

Determination of Range of Splash of Testing Fluid during Hydro Testing of Kni...ijtsrd
There are certain trivial experimental findings which may not have a major significance but their execution is considered to be of such a nature as to complete the study in the specified area. Likewise in the field of hydro testing of valves and flow equipment, there is a basic requirement of operation of the same under influence of applied hydro pressure. This is required to determine the performance parameters like the thrust and the torque required to operate the equipment. While doing so, in addition to the qualitative requirements, an additional requirement of space has to be considered to ensure the surrounding area is not affected due to splashes of the testing fluid while under pressure. This paper shall consider such a case for hydro testing of a knife gate valve. At a given pressure, when the door or gate of the valve is initiated to open, there is an initial splash of testing fluid which ejects out of the orifice created due to the opening. The horizontal range of this splash shall be mathematically determined. An experimental finding shall then be presented to confirm the derived formulae. A conclusion shall be drawn thereafter dictating the percentage error and the employability of the derived formulae.

ubmarine Pipeline BallValves are produced by large number of manufacturer
worldwide. Valves are of actuated/non-actuated and of quarter-turn
valve which uses a hollow, perforated and pivoting ball to control flow.
It opens when the ball’s hole is in line with the flow and closed when it is
pivoted 90-degrees by the valve. Ball valves are durable, performing well after
many cycles, and reliable, closing securely even after long periods of use. The
performance criteria make an excellent choice for shutoff applications.
The ball valve is easy to operate, repair and versatile use portrays to extensive
industrial use and withstanding pressure up to 1000 bar and temperature up
to 752°F (500°C), depending on design and materials used. The size range is
typically from 2 to 48 inches.
API 6D / ISO 14313 are applicable standards for material selection, dimensional
requirement, design features and testing criteria. Wetted parts metallic, non-
metallic and lubricants shall be suitable for the fluid and services complying
project specification.
Allowable stress shall comply the requirements of ASME B31.3. Corrosion
allowance shall be considered and minimum wall thickness shall not be less
than the requirement of ASME B 16.34. Valve design shall ensure repair of stem
seals / gland packing under full line pressure. The valves shall sustain internal
vacuum of five mille-bar in open and closed positions.
Ball valves in sizes up to 2 inches generally come in single piece, two or three piece
design. One piece ball valves are almost always reduced bore design and relatively
inexpensive and generally are throw-away. Two piece ball valves are slightly
reduced (or standard) bore and they can be either throw-away or repairable.The
3 piece design allows for the centre part of the valve containing the ball, stem &
seats to be easily removed from the pipeline.This facilitates efficient cleaning of
deposited sediments, replacement of seats and gland packing’s, polishing out of
small scratches on the ball, all this without removing the pipes from the valve
body. The design concept of a three piece valve that it shall be easily repairable
and re-usable. Valve shall be designed to avoid bimetallic corrosion between
carbon steel and alloy steel parts.Valves shall be provided with anti-static device
to ensure electrical continuity between stem & valve body.
Ball Valves can be full port commonly known as full bore ball valve. This has an
over-sized ball so that the hole in the ball is same as pipeline diameter; resulting
in lower frictional loss. Flow is unrestricted but the valve is larger and more
expensive and only used where free flow is required; for example in pipelines

& Testing Criteria
The article explains on the technical features, selection and testing criteria of submarine pipeline ball valves in detail.
which require pigging. Ball Valve can be reduced port commonly known as
reduced bore ball valve. The flow through the valve is one pipe size smaller than
the valve’s pipe size resulting flow area smaller than pipe section.
As the flow discharge remains constant and is equal to area of flow (A) time’s
velocity (V), the velocity increases with reduced area of flow:
A1 X V1 = A2 X V2
Ball shall be of single piece solid type construction & ball mounting shall be
trunnion type only. The design shall minimise the possibility of debris ingress
into the trunnion. A trunnion ball valve has additional mechanical anchoring
of the ball at the top and bottom, suitable for larger and higher pressure valves
(say, above 10 cm and 40 bars).
Valves shall have double block & bleed feature as per API 6D for complete flush,
drain & venting of body cavity. Seat shall be with primary metal to metal contact
type. Non-metallic O-rings if used for drip tight sealing shall encased in suitable
groove so that it cannot be removed from seat ring and there is no extrusion
during opening or closing operation of valve at maximum differential pressure
corresponding to valve class ratings.
Seat ring design in such a way to ensure sealing at low as well as high differential
pressure. The minimum thick overlay of 4.0 mm of corrosion resistant material
deposited by welding for the internal surface of valve body in contact with
valve seat.
