Lap Joint Flange VS Slip On Flanges

What is a lap joint flange? A Lap Joint Flange (LJ flange/Loose flange) is a two piece device that is much like a weld-neck flange but also like a loose slip on flange. One piece is a sleeve called a ‘Stub-end” and is shaped like a short piece of pipe with a weld bevel on one end and a narrow shoulder on the other end called the hub. The hub is the same outside diameter as the raised face (gasket contact surface) of a weld neck flange. The thickness of the hub is normally about ¼” to 3/8″. The back face of the […]

What is a gasket?

What is a gasket? The gasket is a material made of stainless steel, rubber or metal that is placed between the two planes to reinforce the seal, and a sealing member that is disposed between the static seal faces to prevent fluid leakage. It is usually used to prevent pressure, corrosion, and natural thermal expansion and contraction between two objects. Since the machined surface is not perfect, the gasket can be used to fill the irregularities. The gasket is usually made of sheet material such as mat paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic […]

Fasteners exports ushered in transformation: high-end products cost hundreds o……

Fasteners are the most widely used and the most used mechanical basic parts, and are known as the “industrial rice”. At present, China has become a major fastener manufacturing country, and fastener production has ranked first in the world for many years. However, the product structure of China’s fastener industry is still unreasonable, the product grade is low and the added value is low, which makes it difficult to increase the price. Comparing the export data of fasteners between China and Japan, the export volume of the two countries is very close, which is 9.375 billion US dollars and 9.69 […]

What is LPG pipeline?

What is LPG pipeline? The LPG pipeline (liquefied petroleum gas pipeline) refers to the main pipeline that transports liquefied petroleum gas. Liquefied petroleum gas refers to a mixture of hydrocarbons such as liquid propane, butane, propylene, butylene, and the like. The boiling temperature of propane at normal pressure (101,325 Pa) was _42 t, and butane was 0.5 °C. It is usually pressurized to 0.7 MPa or more at normal temperature or frozen to below minus 42 ° C under normal pressure, and transported by pipeline or canned or shipped. Liquefied petroleum gas must take measures to prevent vaporization during pipeline transportation. […]

Butt welding flange VS Flat welding flange

What is a butt welding flange? A butt weld flange is a flange that has a neck and is transitioned by a round pipe and is butt welded to the pipe. butt welding flange is mainly used for the opposite welding of flange and pipe. Its structure is reasonable, its strength and rigidity are large, it can withstand high temperature and high pressure and repeated bending and temperature fluctuation. The sealing performance is reliable. The nominal pressure is 0.25~2.5MPa. The butt welding flange has a concave and convex sealing surface. Butt welding flange production process Application range of butt welding […]

Sealing elements and principles of pressure vessel flanges

Pressure vessel flanges are common components of pressure vessels and are the basic components for connecting various pressure vessel components. They are widely used in petrochemical, electric power, atomic energy, light industry and other industrial fields. For a container, the flange should be a component, including flanges, gaskets and attachment bolts or studs, and nuts that act to combine the different pressure components while ensuring that the joint does not leak. The main failure mode of the flange connection is the failure of the joint stiffness and its external appearance is leakage. The medium inside the pressure vessel has the […]

Difference among ERW, SSAW, LSAW

What is a ERW pipe? ERW pipe (also called ERW steel pipe) is the abbreviation Electric Resistance Welded Pipes. Electric resistance welding refers to a group of welding process (including spot and seam welding) that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. Specification of ERW steel pipe Production Process for ERW steel pipe What is a […]

Difference between nipple, coupling and union

What is a Pipe Coupling? Pipe Coupling is a short tube, also called an outer joint; it is a commonly used accessory for industrial pipe connections. The forged coupling is formed by heating and forging with a steel ingot or a round bar, and then machined on the lathe to make the thread. The main manufacturing standards are ASME B16.11, BS 3799, and GB/T14383. How to buy pipe couplings How to buy pipe nipples How to buy pipe unions Types of Couplings Types of pipe nipples Types of pipe unions What is a Pipe Nipple What is a Pipe Union […]

Difference between adapter, nipple and union

What is a Pipe Nipple? A pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. The working pressure of […]
