Where to buy high quality stainless steel flange

What is a stainless steel flange? A stainless steel flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. stainless steel flanges are usually welded or screwed. stainless steel flanged joints are made by bolting together two stainless steel flanges with a gasket between them to provide a seal. What is stainless steel? This crystal structure makes such steels non-magnetic and less brittle at low temperatures. For higher hardness and strength, carbon is added. When subjected to adequate heat treatment these steels are used as […]

Corrosion Fatigue Crack Propagation Behavior of 2205 Duplex Stainless Steel in……

Abstract: Experiments of fatigue crack propagation were performed of 2205 duplex stainless steel (2205 DSS) in the deionized water, 3.5%(mass fraction) NaCl solution and atmosphere respectively. It found that in the aqueous solutions the crack growth rate and the fatigue life of the steel was greatly enhanced and reduced respectively. Correspondingly, the influencing degree of the three media can be described respectively as the following two rankings: (da/dN)deionized water>(da/dN)NaCl>(da/dN)atmosphere for fatigue crack propagation rate and Natmosphere>NNaCl>Ndeionized water for fatigue crack propagation life. The fracture morphology revealed that hydrogen induced cracking is the main reason for the deterioration of the fatigue performance of the […]

Steel pipe

What is a steel pipe? A steel pipe is a round steel with a hollow section whose length is much larger than the diameter or circumference. It is divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape; it is divided into carbon steel pipe, stainless steel pipe, alloy steel pipe and composite steel pipe according to the material; it is divided into conveying pipe and engineering structure according to its purpose. For thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, steel pipe for high pressure equipment, etc. According to the production process is divided into seamless steel pipe and welded steel pipe, which seamless […]

Pipe fittings

What are pipe fittings? Pipe fittings are collectively referred to as components that play the role of connecting, controlling, redirecting, diverting, sealing, supporting, etc. in a piping system. According to the different processing techniques, there are four major categories, namely butt-welding pipe fittings (having two kinds of welds and no welds), socket welding and screw fittings. Classification of fittings There are many types of pipe fittings, which are classified according to their use, connection, materials, and processing methods. By usage 1. Fittings for connecting pipes to each other: flanges, unions, pipe clamps, clamps, ferrules, hose clamps, etc. 2, Change the direction of the […]

Flange

What is a flange? A flange is a part that connects a pipe to a pipe, and is connected to a pipe end. There are holes in the flange, and bolts make the two flanges tight. The flanges are sealed with a gasket. Flanged pipe fittings are pipe fittings with flanges (flange or socket). It can be cast (not shown), it can also be threaded or welded. A flange joint consists of a pair of flanges, a washer, and bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the […]

Where to get high quality reducing flange

What is a Reducing Flange? A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size. Reducing Flanges are suitable for changing line size, but should not be used if abrupt transition would create undesirable turbulence, as at pump connections. Reducing flanges are designed for when there is a change in the pipe size. The predominate flange (dimensions) matching the larger pipe size (NPT) but having a smaller bore matching the smaller pipe size (NPT). These flanges normally […]

Life Prediction for Stress Corrosion Behavior of 316L Stainless Steel Elbow of……

GUO Shu, HAN En-Hou, WANG Haitao, ZHANG Zhiming, WANG Jianqiu Key Laboratory of Nuclear Materials and Safety Assessment, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China Abstract: Stress corrosion cracking (SCC) is one of the main ageing mechanism in light water reactor (LWR). 316L austenitic stainless steel was adopted in nuclear industry for its relatively high corrosion resistance. The SCC of austenitic stainless steel may occur as it is subjected to both the tensile stress and the caustic medium, with regard to maintaining the structural integrity of components in nuclear power plant, an accurate prediction and efficient […]
