Introduction of ASTM A234 / ASTM A234M Under ASTM A234 specification covers wrought carbon steel and alloy steel fittings of seamless and welded fitting materials. Design, dimension, tolerance, testing will be followed in ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are only applicable for pressure piping and vessel fabrication for service at […]
Materials of Construction – (MOC) The selection of material of construction for plant’s equipment, fitting, composite fitting like (elbow, tee, reducer, pipes, flange, orifice, valve, steam traps, NRV) etc. play a crucial role to sustain, reliable and life of itself. That must be based on various factors for setup a process plant. There are a
What are stub-in and stub-on connection Stub-in is a type of branch from a run pipe that is fabricated by making a hole of approx 6mm larger than the outer diameter of the branch pipe. The stub-in is usually used when the branch is more than one size smaller than the main run pipe. The
General Knowledge Of ASTM A216 This covers materials specification of carbon steel castings materials for Valves, all types of flanges, all types of fittings, or other pressure-containing parts for high-temperature service and suitable for assembly with other castings or wrought-steel parts by fusion welding. Within the ASTMA216 materials grade cover three grades, WCA, WCB, and
General knowledge of ASME B16.11 ASME B16.11 is a standard for the forged steel fittings of pipeline, in which cover all details like pressure ratings, dimensions, tolerances, marking and material requirements for socket weld and threaded fitting only. But for special requirements of forged fittings with special dimensions, threads, or counter bores may be made
Difference between centrifugal pump and Reciprocating pumps Centrifugal Pump: Reciprocating Pump: 1. Working principle Centrifugal Pump is a type of dynamic type pump that discharges the liquid at uniform pressure over a range of flow. Then it drops dramatically as the flow rate increases by the help of the driver (Motor) rotate the impeller (mounting
What is a tee in pipe fitting? Pipe Tee is a most frequently used pipe fitting or connector nowadays. It functions the same as olets that means it is used to take a branch connection for linear pipeline. As the name TEE represents, the shape is T-shaped with two outlets, at 90° to the connection
What is a reducer in piping? A reducer is a kind of pipe fitting (accessory) which is used in process piping to change the pipe size from a big bore to a smaller bore pipe. Mostly reducer use for a change in pipe size to meet flow requirements of the process system or connect to
What is Latrolet fitting? Latrolet is a type of self-reinforcing branch fitting accessories for pipe-line. As its names represent how that will connect to the run pipe (header pipe). Latrolet fitting was developed by a company called Bonney Forge. And this is mostly suitable for small bore branch connection pipes. A Latrolet is available in
What is a threadolet used for? Threadolet is used for 90 degree self-reinforcing branch accessories for pipe line fitting. As its names represent how that will connect to the run pipe (header pipe). Threadolet is a type of self-reinforced branch fitting developed by a company called Bonney Forge. And this is suitable for small bore
What is a Sockolet used for? Sockolet is used for 90 degree self-reinforcing branch accessories for pipe line fitting. As its names represent how that will connect to the run pipe (header pipe). Sockolet is a type of self-reinforced branch fitting developed by a company called Bonney Forge. And this is suitable for small bore
Definition of Weldolet? Weldolet fitting is one of the most common types of piping components and this is a type of Olets. This is used for take branch connection from run pipe lines to branch pipe line and connected by butt weld welding process with 90° branch connection. In weldolet both ends will be beveled, mostly
