A Brief Overview of Pipe Fittings

What are Pipe Fittings? Pipe fittings are the objects that holds the whole piping system together. This is because they make the pipes usable and help route the water to where it needs to go. When a bathroom remodel is done, these carbon steel pipe fittings may also need to be worked with in order to make sure they are doing what they need to be doing. If they are not there, then the whole thing will not work at all. Pipe fittings are widely used in plumbing systems to join tubing sections and straight pipes to adapt to varied […]

What is a hot rolled seamless steel pipe?

What is a hot rolled seamless steel pipe? Hot-rolled seamless steel pipe is a large category of seamless steel pipe, which is divided according to the production method. Hot rolling is relative to cold rolling, cold rolling is carried out rolling at room temperature, and hot rolling is carried out rolling at the recrystallization temperature. Seamless steel pipe is named relative to the welded steel pipe, seamless steel pipe is usually made of round steel perforation and reprocessing, welded steel pipe is usually welded by steel plate in different ways. The diameter of hot-rolled seamless steel pipe is usually above […]

General Information About Flanges

What is a flange?Flange is a major component for connecting two pipes. Generally speaking, it connects the ends of two pipes through threading or welding. Thus, flanges are classified into two big categories according to attended modes: threaded connection (screwed) flanges and welding flanges. If two pipes are arranged to be connected, a pair of flanges, a gasket and several bolts and nuts are needed to complete the flange joint. At first, put the gasket between two sealing faces. Then, tighten the bolts. When the gasket surface pressure reaches a certain level, it would be deformed to fill the uneven […]

What is a blind pipe flange?

What is a blind pipe flange? A Blind pipe flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened. The blind pipe flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind […]

What are forged fittings?

What are forged fittings? Forged fittings are used to connect, branch, blind or route small diameter piping systems (generally, below 2 inches). Contrary to butt weld fittings, which are manufactured from pipes and plates, forged fittings are produced by forging and machining steel. Forged fittings are available in multiple shapes, sizes (bore sizes and pressure ratings) and forged material grades (the most common are ASTM A105, ASTM A350 LF1/2/3/6 for low-temperatures, ASTM 182 for corrosive, high-temperature applications). Forged fittings are connected to pipes by socket weld or threaded connections. ASME B16.11 is the reference specification. Forged fittings are manufactured according to the ASME B16.11, MSS SP 75, […]

Experimental Study on Local Erosion of 304 Stainless Steel Bends with Gas Carr……

Abstract: Experimental study on local erosion of 304 stainless steel bends with gas carrying sand induced by SiO2 sand blast was studied in terms of wall thickness loss along the band periphery and micro-morphology on the inner wall surface of the longitudinal section of a band after erosion test. The result shows that the erosion of the stainless steel bend caused by sand particles is mainly concentrated on the outer half of the band and the ratio of the mass loss of the outer half to that of the inner half of a band, namely index α, increases with the increase of […]

What is a steel pipe?

What is a steel pipe?A steel pipe is a round hollow section manufactured by drawing a solid billet (in carbon, alloy, stainless or nickel alloy steel) through a piercing rod. Seamless pipes are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.Seamless steel pipes are used for the transmission and distribution of oil, gas, steam, and chemicals. Stainless steel seamless pipes offer enhanced resistance to corrosion at high temperature and pressure. Seamless steel pipes have a higher price per ton than welded pipes, due to their fairly complex production […]

What are butt weld fittings?

What are butt weld fittings? Butt weld fittings are to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe.In the case of forged steel butt weld fittings, you would find them to be manufactured according to ANSI/ASME B16.9.Also known by welded pipe fittingsButt weld fittings would also be referred to as welded pipe fittings. When these would be used in stainless steel and carbon steel, they would be able to offer certain advantages […]

What are Flange Gaskets?

What are Flange Gaskets? Flange Gaskets are used to create a static seal between two flanges faces, at various operating conditions, with varied pressure and temperature ratings. A gaskets fills the microscopic spaces and irregularities of the flange faces, and then it forms a seal that is designed to keep liquids and gases. Correct installation of damage-free gaskets and demage-free flange faces is a requirement for a leak-free flange connection.If it would be technically possible, in order to manufacture flanges perfectly flat and smooth, and perfectly compatible with one another under all operating conditions, a gasket would not be necessary. […]

What is a flange?

What is a flange? A pipe flange is a mechanical device to join pipes. Flanges are available in multiple shapes, as welding neck (the pipe is welded to the collar of the flange), threaded (the pipe is screwed on the flange), socket weld (fillet welds connections), lap joint (for connections using stub ends), slip on, etc. The ASME B16.5 and ASME B16.47 specifications cover US standard pipe flanges, the EN 1092-1 specification covers European steel flanges. Pipe flanges are available in dimensions between 1/8 and 80 inches and in multiple (forged) material grades as ASTM A105 (carbon steel flanges for high-temperature service), ASTM A350 (CS flanges for low temperature), ASTM […]
