ASME B16.5 Class 150 High Yield Carbon Steel F70 Slip On/ Blind Flanges manufacturer At Lowest Possible Price In Mumbai, India


ASTM A694 F70 Flanges

Flange made as per ASTM specification is further subdivided into various grades. These grades specify the features of the flange. ASTM A694 F70 Flanges is one such grade that is utilized in high pressure piping transmission systems. They have a good sturdiness and offer long service life, this reduces the cost thus making them cost efficient. As per  High Yield Carbon Steel F70 Slip On Flange manufacturer In India recommends these flanges for low pressure applications. They make the joints of the pipe stronger. It is manufactured using alloy steel, carbon steel, or low alloy steel.

These steels used in Carbon Steel F70 Blind Flanges can be made using electric furnace basic oxygen process, or open hearth and can be fully deoxidized. They are usually manufactured using, bars, billets, ingots, or slabs. However, these ASME SA 694 F70 Weld Neck Flange cannot be formed using solid plates or solid bar stocks. This is due to the reason that sufficient hot working/ forging is required to develop a wrought structure. Carbon Steel F70 Socket Weld Flanges consisting of carbon steel or high strength low alloy steel may be heat treated by normalizing, normalizing, and tempering or quenching and tempering. 

A694 Grade F70 RTJ Flanges with alloy steel may consist of quenching and precipitation heat treatment or normalizing and precipitation heat treatment. A temperature of 1000 degrees F is prefered87 for tempering these flanges. A694 Grade F70 Plate Flanges are used in pipelines, chemical industries, oil and gas industries, food processing industries, and power industries. Furthermore, these SA694 Gr F70 Threaded Flanges are also used in shipbuilding industries, equipment industries, and so on. We have been producing these flanges for generations and have been supplying them to our customers at competitive prices without compromising on the quality of it.
