The passivation process of marine flanges can be divided into two types: wet and dry. Specifically can be divided into a variety of types. The following follow the automotive aluminum alloy flange small editor to take a brief look!

Whether the passivation effect depends on the surface passivation treatment process, but also depends on the material itself, the specific factors affecting the elements contained in the marine flange, stainless steel metallurgical analysis of the structure, stainless steel processing technology status. In the composition of an element, chromium, nickel belongs to the passivation of strong elements, iron passivation of the second, therefore, chromium, nickel content is getting higher and higher, stainless steel passivation of the role of the stronger. Austenitic, ferritic type comparison between large equipment flange has a more uniform organization , passivation can be better, martensitic type stainless steel company strengthened by heat treatment, its metallurgical organization for the multiphase system organization, and thus passivation is not strong. Marine flange processed by mechanical design of the passivation of the smooth profile of the environment is better, forging, sandblasting and other different workpieces obtained from the basic profile rough, obscure passivation.
The material not only has a creep curve through and through, while its price is moderate pipe, each melt form of reliable standard hot melt connection, pipe part than the inner diameter of the pipe of the aperture is larger than the different from the specifications relative to other kinds of structure is convenient, quick , stage connection type in the system belongs to the product due to local necking of the absence of mechanical connection, the system will be relatively small resistance to the fluid. However, due to various factors, the actual wall thickness of the floor heating pipe is usually only 2mm. and in various types of pipe wall thickness can meet the requirements of the floor heating, the pressure and its advantages will easily emerge .
Low-temperature thermal shock resistance: PE--RT and PEX products have good low-temperature shock resistance. In the winter construction pipe is not easy to be impacted and cut , thus increasing the construction placement of the orthopedic.
The above is the automotive aluminum alloy flange small talk about some of the introduction of the marine flange, I hope to help you.
