Correlation analysis of water hammer in pipeline for bellows compensators

Bellows compensators are also known as expansion joints and expansion joints. They consist of bellows (an elastic element) which comprise the main part of the work, and end pipe, bracket, flange, pipe and so on. Is a size change with deformation compensation device to effectively use telescopic elastic element and bellows reasons to absorb pipeline, conduit […]

Measures to Improve Impact Toughness of Duplex Stainless Steel Pipe Fittings

Generally, the measures taken to improve the impact toughness of duplex stainless steel fittings are nothing but the following: 1. reduce the carbon content of dual phase steel pipe fittings; 2., increase the ratio of manganese to carbon (Mn/c); 3. adding alloying elements, such as Ni, Cr, Mo, etc.; 4. reduce sulfur content; 5. reduce the sulfur […]

Heat treatment of stainless steel head

Stainless steel head in the heating and cooling process, the stainless steel head due to the surface and the heart of the cooling rate and time inconsistency, the formation of temperature difference, it will lead to volume expansion and shrinkage uneven stress, that is, thermal stress. Under the action of thermal stress, because the surface temperature […]

Corrosion resistance of stainless steel pipe fittings in different environments

1. The atmospheric corrosion The corrosion resistance of the stainless steel pipe fitting is basically the amount of chloride in the atmosphere. Therefore, it is extremely important to be near the ocean or other chloride sources to corrode stainless steel pipe fitting parts. A certain amount of rain is important only when the chloride concentration of the […]
