Technolloy Inc is a well-established manufacturer of blind flanges with ten years of experience. An ASTM A105 Blind Flange belongs in a specification of flanges that covers different grades of stainless steel. Along with nickel and chromium, the material usually comprises manganese, silicon, copper, molybdenum and vanadium. Blind flanges block the passage of fluids as they lack a suitable opening for passage. These fittings cater to high-temperature applications because of their dependable yield strength, tensile strength, and hardness (Brinell hardness score of 187).

ASTM A105 flanges can undergo forging as long as the guidelines for welding get carefully followed. The company supplies these components at unmatched prices and provides corresponding pressure test reports and heat treatment test certificates.

High-temperature environments require specific flanges that can withstand severe conditions without undergoing deformation. An ASME SA105 Weld Neck Flange falls under the specification for carbon steel flanges designed for such applications. Weld Neck Flanges are also called tapered or high-hub flanges. They effectively relocate stress to the piping and usually get welded to the pipe.

These flanges adapt well to adverse conditions because of their superior mechanical properties and tensile strength. The fittings also offer high resistance to corrosion – pitting, crevice, and stress cracking. The company provides customized fittings based on the as customer requirements.

Normalized carbon steel is a material that has undergone heat treatment at high temperatures and cooled in a furnace. This carbon steel has a refined microstructure making it lower in hardness and more ductile. The process also minimizes internal stress that could induce failure. A Class 300 flange with this material gets manufactured to withstand high pressure. It can tolerate 570 psi at 600 degrees Fahrenheit.

An A105 Slip on Flange offers several advantages in easy installation and alignment of bolts. It gets used in pressure systems that operate under varying temperatures. The core mechanism involves a ring placed over the pipe end. The internal diameter is more than the piping to permit the fitting to slip on. However, the limited or partial welding limits the usage in adverse conditions.

An A105 Lap Joint Flange uses forged carbon steel components for both ambient and high temperatures. It can be used in pressure systems and is helpful in connections that can be difficult to adjust. These fittings consist of a stub end and a ring placed over it. The former gets welded to the piping while the ring aligns with the flange. The generated seal is secure because the pressure during bolting gets transferred to the gasket.

Another commonly used fitting is a Threaded Flange (also called a screwed flange). Here, the male thread gets screwed into the female threaded flange. Their standout advantage is easy installation because they don’t require welding. It also limits their utility in high-pressure or high-temperature environments.

The manufacture of A105 forged Flanges involves forging at high temperatures between 1,700 °F and 2,200 °F. Subsequently, the material undergoes quenching and tempering. Finally, the A105 flange gets reheated to 1,550 °F (up to 1,700 °F) and experiences slow cooling.

The standard specification ASTM A105 does not mandate heat treatment except for fittings above Class 300. The usual approaches include annealing, normalizing, and quenching.

The prices for ASTM A105 forged Flanges vary based on the desired thickness and other dimensions. The approximate price in India for a 1/2″ to 48″ component is Rs 190 apiece. Weld neck flanges can cost Rs 450 a piece, while blind flanges and slip on components are cheaper.
