What is water hammer? Water hammer is a pressure surge or wave resulting when a fluid in motion is forced to stop or change the velocity. A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock. A signifcant, nearly instantaneous pressure shock wave may be generated when a valve opens or closes too quickly, or when a pump starts with an empty discharge line or suddenly shuts down. This phenomenon is the result of the sudden change in velocity of the fluid … Continue reading Water hammer in piping system ( Part 1 )

API 5L Pipe general: API 5L pipes is used for conveying gas, water and oil either in the oil or natural gas industries. Line pipe can meet all requirement of high-pressure transmission pipeline for natural gas & petroleum, can be used in on-shore, off-shore oil & gas transmission. API 5L ~ American Petroleum Institute specification API 5L cover seamless or welded steel line pipe. The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries. Grade: Grades covered by this specification are A25, A, … Continue reading PIPE API 5L: PSL1 vs PSL2

1) Piping: Piping includes pipe, flanges, fittings, bolting, gaskets, valves, and the pressurecontaining portions of other piping components. It also includes pipe hangers andsupports and other items necessary to prevent overpressurization and overstressing of the pressure-containing components. It is evident that pipe is one element or a part of piping. Therefore, pipe sections when joined with fittings, valves, and other mechanical equipment and properly supported by hangers and supports, are called piping. 2) Piping system: Interconnected piping subject to the same sets of design conditions. 3) Piping components: Mechanical element suitable for joining or assembly into pressure tight fluid containing … Continue reading PIPING vs PIPING SYSTEM
