Werner Flanges Inc. is one of the prominent manufacturers, traders and exporters of ASME B16.47 Class 900 Series B Blind Flanges, which are fairly susceptible to sigma phase formation in the temperature range 590 Degree C to 870 Degree C. We are a known ASME B16.47 Class 900 Series B Blind Flange Manufacturers in India, where it can be relevant in high temperature applications and is the thermal expansion of the particular material. Because sigma phase embrittlement is a serious problem by means of the high silicon of our SME B16.47 Class 900 Series B Blind Flanges Dimensions, this is now largely replaced by high nickel alloys or by steels resistant to sigma phase embrittlement.

As a Distributor of ASME B16.47 Class 900 Series B Blind Flanges, it may perhaps not be suitable for exposure at this comparatively low temperature range and is often a better choice. Other factors which can be important in the use of our Series B Class 900 Blind Flanges for high temperature applications are carburisation and sulphidation resistance.

Sulphur bearing gases under reducing conditions greatly accelerate the attack on these Titanium Alloy Blind Flange by means of high nickel contents. In some instances, our ASME / ANSI B16.47 BLRF Flange have given reasonable service by means of lower nickel content is better, but in others a totally nickel – free alloy is superior.
