In Internet I came across a fantastic Pipe support standard, so I thought of sharing the same with our blog readers.

Every company will have their own Pipe support standards, but still something will be missing when you see others standard. So have look.

This booklet has been written as an introduction to and a
source of general information on pipe joints.
The flanged joint appears deceptively simple but in fact the
science of flanges and joint sealing is complex and continuously
developing. Sound joints are critical to piping integrity and
plant safety.

Typical Process Vent / Hydro Test Vent & Drain Assemblies

Posted by Antony Thomas at Wednesday, June 27, 2012

Typical Process Vent / Hydro Test Vent & Drain Assemblies

Classification of Vent Assembly:

Vent assemblies can be broadly classified as Process Vents and Hydrostatic Test Vents.

Process Vent:

During the process of a system, some vents needs to be operated very often (e.g start-up, shutdown and maintenance, etc.).  So there should be a proper venting assembly for the whole life cycle of the piping system.  This assembly should have valve so that after venting, the valve can be closed and continue the normal operation. Air must also be released from pipe to allow filling and admitted to permit draining or pumping out liquids. Selection of Process vent assembly is based on the piping class. Some of the typical Process Vent assemblies are shown below.

Process Vent Assembly-1 & 2
Process Vent Assembly-1 & 2

Process Vent Assembly-3 & 4
Process Vent Assembly-3 & 4

Process Vent Assembly- 5 & 6
Process Vent Assembly-5 & 6

Hydro Test Vent:

During the Hydro Test of a piping system, the air inside the pipe will be trapped at higher elevations when supplying the water inside the pipe. This trapped air needs to be removed before testing. For these purpose Hydro Vents will be provided at each higher elevations of a piping system. Vents are needed to let air in and out of systems.  Some type of hydro test vent caps are seal welded after the testing. Typical Hydro Test Vent assemblies are shown below.

Hydro Test Vent Assembly-1 & 2
Hydro Test Vent Assembly-1 & 2

Hydro Test Vent Assembly- 3 & 4
Hydro Test Vent Assembly- 3 & 4

Hydro Test Vent Assembly-5
Hydro Test Vent Assembly-5

Drain Assembly:

Normally drain assemblies are provided in a piping system to drain out the process liquid as well as the water after the hydro test. The Hydro test drains are used as process drains during the process cycle. Typical Drain assemblies are shown below.

Drain Assembly-1 & 2
Drain Assembly-1 & 2

Drain Assembly- 3 & 4
Drain Assembly- 3 & 4

Drain Assembly- 5 & 6
Drain Assembly- 5 & 6

Hydro Test Vent/Drain Assembly Locations:

PIDs show only Process vents such as vacuum breakers and process drains. Positions of the required vent and drain points are established on the piping drawings. Typical hydro test vent assembly and drain assembly locations are shown below for reference purpose.

Check valve is used to stop back flow in a piping system. This is also called Non return Valve (NRV)
Check valves are available in the following designs:
ü  Swing Check Valves
ü  Tilting Disk Check Valves
ü  Wafer Check Valves
ü  Disk Check
ü  Piston Check
ü  Ball Check
ü  Duo-Check Valves
ü  Non-Slam Check Valves


Swing Check Valve DiagramSwing Check Valve Picture
Swing Check Valves are available in straight body design and y-pattern design. The disk is suspended from the body by means of a hinge pin and seals against the seat which is integral with the body. These valves are typically used in sizes 2 inches and over. Swing check valves can be installed in both horizontal and vertical position. They are not suitable for pulsating flow.
Closure response of swing check valve is slower compared to lift check valve due to longer disc travel and inertia of disk.
Industry Codes and Standards
·         Valve Design:     BS 1868 / API 6D
·         Pressure Testing:             BS 6755-I
·         Face To Face:     ANSI B 16.10
·         Flange Drilling:   ANSI B 16.5 / BS 10 Table / DIN / IS / JIS Std.
·         Butt Weld End:  ANSI B 16.25
·         Face to Face: ANSI B 16.10
·         Socket Weld End: ANSI B 16.11
·         Screwed End: ANSI B 1.20.1(BSP/NPT)



Tilting Disk Check Valves fit between two flanges and provide a compact installation for large diameter applications. These valves can be installed in horizontal and vertical lines. They provide a quick closing response and are particularly suited for pulsating flows with compressible fluids.
· Face to Face: ANSI B 16.10


Wafer Type Check Valve has short face-to-face dimensions and low weight allows a simple space saving installation between the companion flanges. The valves are suitable to mounting between weld neck or slip on type companion flanges of different standards.
They are specially developed for applications where a low-pressure loss is essential. Opening and closing of the valve will take place at an extremely low-pressure difference over the valve disc. The eccentric disc shaft combination with the disc seat guarantees a positive shut off returning media. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design and relatively low cost.

· Face to Face: ANSI B 16.10


The Single Disc Check Valve (Wafer Type Disc Check Valve) consists of four main components: the body, a disc, a star guide and a spring. The Disc check valves are opened by the pressure of fluid and closed through compression spring as soon as flow stops thus preventing reverse flow.
The design of Wafer Design, Sandwich Type Single Disc Spring Loaded Check Valves allows them to be installed between any flanges of different standard and in any position; including vertical pipelines where the fluid flows downwards.


Piston Check valves are generally used to protect pumps or similar equipment, allowing the flow only in one direction and preventing flow reversal due to back pressure. The piston check valves are designed with globe valve bodies, producing an increased drop pressure in the pipeline. This design provides a tight seal as well as a fast reaction to the closure impulse. Metal seated check valves may not provide drop tight sealing when used in gas system or fluid system with low back flow pressure or fluids containing particles.
· Face to Face: ANSI B 16.10


The ball check valve is one of the few check valves that works well in both water and wastewater applications. Ball check valves are simple in operation and commonly used on small pumps and in low head systems. Consider adding an optional roll-bar to the piping system for safety; ball check valves have the highest tendency to slam due to the ball's high inertia long stroke. When ball check valves encounter high pressures and dynamics, severe slamming may result.
· Face to Face: ANSI B 16.10


dual plate check valveDuo CHECK VALVE PICTURE
The Dual Plate, Wafer Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE. It is much easier to install between standard gaskets and line flanges, and therefore is more cost effective to install and to maintain. Its design complies with API 594 and API 6D, testing with API 598. It is also called as Butterfly Check Valve.


It is essential to see the closing characteristic of the valve with the dynamics of the pumping system.

non-slam check valve 

The swing check valve closes abruptly because of gravity, and causes pressure surge resulting in shock waves. These high pressure waves causes sever stress on the piping system. This problem can be minimized by installing a Non-Slam type check valve. Non-Slam check valve do not rely on gravity. As the upstream velocity of the fluid slows the spring assist on the valve start to close the disc. By the time the upstream velocity comes to 0, the disc is completely closed. With the reverse flow eliminated, the force necessary to produce water hammer on either side of the valve are substantially reduced.
