Recently, a batch of 2″- 28″ flanges, material: A105, standard: ASME B16.5/ASME B16.47. Those flanges are about to be shipped to Mexico. The customer wants to do a low temperature impact test before delivery. As we all know that the low temperature impact test refers to the degree of ...

Flange as steel products are easy to rust corrosion, which will shorten its service life. So we should pay attention to the surface anti-corrosion of flange. Lately, a new customer sent me an inquiry. During the communication, he told me that there was a large area of rust after the flange bough ...

Although forged flange and machined flange are of the same kind, actually they are quite different. Today I will introduce the difference between those two flanges briefly. EN 1092 1 forged slip on flanges The forging process of flange is generally lower in carbon and less prone to rust than tha ...

Generally, in the pipeline connection, there are often some dangerous factors, including leakage, galvanic corrosion and static electricity, which cause accidents. Therefore, the common flange connection is not enough, and the insulating flange with insulation characteristics must be used. Here, ...

An insulating flange can also be referred to as flange insulation kid or flange isolation kid(FIK). Insulating flanges are those flanges equipped with plastic parts that insulate and prevent the flow of current between two metal surfaces.Insulating flanges are used in cathodic protection systems ...

Blind flanges are the most used flanges,our flange products are widely used in the following industries: oil,gas, chemical,shipbuliding,water treatment,power plant,steam,construction and other fields all over the world.The application area of blind flanges as follows: ANSI B16.5 ASTM A182 F304 b ...

Flange sealing cover is basically: Full-plane FF protruding surface RF concave surface FM convex surface M tenon surface T groove surface G ring connection surface RTJ(RJ) five types, according to the working conditions, media, pressure, specifications, temperature and other conditions, so the t ...

Reasons for stainless steel rust: The surface of the stainless steel contains dust or other metal particles attached to other metal elements. In humid air, the condensed water between the attached material and the stainless steel connects the two into a micro battery, triggering an electrochemic ...

The chemical polishing of stainless steel flanges is achieved by the regular dissolution of the flange surface to achieve a smooth and smooth finish. In the chemical polishing process, the passivation oxide film and the oxide film are continuously formed on the surface of the steel stainless ste ...

Marine flange gaskets are a kind of ring made of material which can produce plastic deformation and have certain strength. Most gaskets are cut from non-metallic sheets, or are manufactured by specialized factories according to specifications: size, the materials are asbestos rubber sheets, asbe ...

Flange rolling is also a flange manufacturing process. Plate flat welding flange in the majority, the connection mode for welding. There are cold rolls and hot rolls. Materials are carbon steel, stainless steel, alloy steel and so on. This kind of product uses theory weight to weigh mostly, do n ...

Marine socket weld flange refers to the flange which is welded at the end and outside of the pipe by inserting the end of the pipe into the step of the flange ring. The flange with neck has good rigidity, small welding deformation and good sealing property. It can be used in pressure range of 1. ...
