What factors should be considered when selecting the pressure rating of the takeover flange?

In engineering design, the pressure level of the nozzle flange of the container is usually given by the professional of the process system. The following factors should be considered when selecting the pressure rating of the takeover flange. 1 Design pressure and design temperature of the container; 2 Connection standards of valves directly connected to them, valves, […]

Installation instructions and correct sequence of stainless steel flanges

There are more and more kinds of stainless steel flanges in the production process, for different kinds of flanges, installation methods are also different, then for everyone to introduce the correct installation sequence of stainless steel flanges. The stainless steel pipe or stainless steel pipe fittings contaminated before the stainless steel flange connection should be cleaned up. […]

Properties and classification of duplex stainless steel

The biphase in the name of the duplex stainless steel is mainly derived from the microstructure of the alloy. The duplex stainless steel usually contains about 50/50 austenite and delta ferrite phase mixture. Compared to austenitic stainless steel (for example, 304 or 316 stainless steel), duplex stainless steel has better corrosion resistance, especially chloride stress corrosion and […]

Why are the price of 317L stainless steel flanges higher than 316 and 304 stainless steel flanges?

There are hundreds of different types of stainless steel flanges on the market, which may be difficult to find the perfect metal for your application. In many purchasing processes, the cost of metals is the first consideration rather than the performance of metals, but this is wrong. In some cases, additional costs are required for different high-performance alloys. […]

The problem of sensitizing reaction of austenitic stainless steel

In the temperature range of 950-1450°F, chromium carbide tends to precipitate at the grain boundary of austenitic stainless steel. Any exposure or thermal excursion within this temperature range during metal manufacture and use may cause sensitization of the austenitic stainless steel. Common practices such as welding, stress relief and thermoforming can make stainless steel reach the […]

The difference between butt welding and flat welding in stainless steel flanges

The difference between the flat welding and the butt welding of the stainless steel flange refers to the two welding methods when the flange is connected with the stainless steel pipe. The flat welding flange welds only one side, without welding the inner mouth of the welded stainless steel pipe and flange. The welding and installation of […]
