Different types of Ball Valves
Ball valve is a ball that is literally placed in a passageway through which there is a flow of the fluid. You would find that there is a hole in the ball where the ball opens as well as closes. There are some ball valves that permit only 90 [...]

Pipe Flange Joint Poses Safety Concerns
A fuel gas pipeline in a pipe trench went under a road bridge inside a factory.  A flange joint, fitted with a compressed asbestos fiber (caf) gasket, was located only 2.5 m from the roadway.
According to the area classification code used by the company there was [...]

Stainless Steel Pipe,stainless Steel Seamless Pipe
My company couldn’t see all the fuss. We had been hired by Bechtel as a subcontractor for the ill-fated Goro project to refine nickel ore in New Caledonia. Bechtel wanted us to match its pipe specifications. To us, this was just another symptom of a bloated project. We used [...]

Hydraulic for Seals, fittings and connections

Hydraulic for Seals, fittings and connections
by Piping Engineer March 17, 2009 Mechanical/Rotating Equipment

In general, valves, cylinders and pumps have female threaded bosses for the fluid connection, and hoses have female ends with captive nuts. A male-male fitting is chosen to connect the two. Many standardized systems are in use.
Fittings serve several purposes:
-To bridge different standards; O-ring boss to JIC (hydraulic), or pipe threads to face seal, for [...]

Hydraulic hose

Hydraulic hose
by Piping Engineer March 17, 2009 Mechanical/Rotating Equipment

Hydraulic hose is graded by pressure, temperature, and fluid compatibility. Hoses are used when pipes or tubes can not be used, usually to provide flexibility for machine operation or maintenance. The hose is built up with rubber and steel layers. A rubber interior is surrounded by multiple layers of woven wire and rubber. The exterior [...]

Hydraulic pipe

Hydraulic pipe
by Piping Engineer March 17, 2009 Piping/Stress Group

Hydraulic pipe is used in case standard hydraulic tubes are not available. Generally these are used for low pressure. They can be connected by threaded connections, but usually by welds. Because of the larger diameters the pipe can usually be inspected internally after welding. Black pipe is non-galvanized and suitable for welding.

Hydraulic tubes

Hydraulic tubes
by Piping Engineer March 17, 2009 Piping/Stress Group

Hydraulic tubes are seamless steel precision pipes, specially manufactured for hydraulics. The tubes have standard sizes for different pressure ranges, with standard diameters up to 100 mm. The tubes are supplied by manufacturers in lengths of 6 m, cleaned, oiled and plugged. The tubes are interconnected by different types of flanges (especially for the larger [...]

Hydraulic Filter

Hydraulic Filter
by Piping Engineer March 17, 2009 Mechanical/Rotating Equipment

Filters are an important part of hydraulic systems. Metal particles are continually produced by mechanical components and need to be removed along with other contaminants.
Filters may be positioned in many locations. The filter may be located between the reservoir and the pump intake. Blockage of the filter will cause cavitation and possibly failure of the [...]

Hydraulic fluid

Hydraulic fluid
by Piping Engineer March 17, 2009 Mechanical/Rotating Equipment

Also known as tractor fluid, hydraulic fluid is the life of the hydraulic circuit. It is usually petroleum oil with various additives. Some hydraulic machines require fire resistant fluids, depending on their applications.
In addition to transferring energy, hydraulic fluid needs to lubricate components, suspend contaminants and metal filings for transport to the filter, and to [...]

Hydraulic pump

Hydraulic pump
by Piping Engineer March 17, 2009 Mechanical/Rotating Equipment

Hydraulic pumps supply fluid to the components in the system. Pressure in the system develops in reaction to the load. Hence, a pump rated for 5,000 psi is capable of maintaining flow against a load of 5,000 psi.
Pumps have a power density about ten times greater than an electric motor (by volume). They are powered [...]
