F316 vs F316L in Process Piping ASTM A182 F316 and F316L are both grades of forged stainless steel flanges commonly used in process piping according to ASME B31.3, in which corrosive environments are involved. ASTM A182 Grade F316 is a standard molybdenum-bearing austenitic stainless steel with a higher chromium content than F304, providing improved corrosion resistance, particularly against chloride ion …

We are excited to introduce our top-quality ASTM A694 F65 flanges, supplied specifically for the Chevron Bibiyana Gas Plant project, Bangladesh. Our flanges are manufactured to meet the stringent requirements of the oil and gas industry, ensuring durability, reliability, and performance in challenging environments. Features and Advantages High Strength ASTM A694 F65 flanges exhibit exceptional tensile strength and yield strength, …

Inconel alloy 625 weld overlay on carbon or low-alloy steel piping components Inconel alloy 625 is a nickel-chromium-molybdenum alloy known for its UNS designation N06625. It exhibits outstanding and versatile corrosion resistance and high strength (tensile, creep, rupture, fatigue) under a wide range of temperatures and pressures. However, because of the high price tag, piping components made of homogeneous Inconel …

Characteristics, welding & applications In order to enhance the corrosion resistance of the ring-type-joint (RTJ) sealing face of a carbon steel or low alloy steel flange, a layer or multiple layers of corrosion-resistant alloy Inconel 625 are deposited onto the surface of the RTJ groove of the flange through a arc welding process. The carbon or low alloy steel flanges …

Stub ends manufactured to ASME B16.9 can be classified as long pattern or short pattern. A stub end works together with a backing flange (usually lap-joint type) to form an economical assembly, in which the backing flange is made of cheap carbon steel while the wetted stub end may be provided in expensive corrosion-resistant alloys such as stainless steels, nickel …

G.A. Drawing & Design Features As specified by EN 594 and BS 5155, the U-section butterfly valve is a wafer-style valve with two flanged ends. Unlike the conventional double-flanged butterfly valve, although two integral flanges are integrally cast on the body, the internal space between the two integral flanges are too small for them to be bolted up with pipe …

Technical Drawing & Design Features Wafer type butterfly valves, either made of cast grey iron or ductile iron, can be further classified according to the way its disc is attached to the shaft. If the disc is attached to the shaft by using a through taper pin, it is called pinned disc or disc with pin; If the disc is …

Technical Drawing & Function The ASME B16.11 bushing has male threads on the surface of outside diameter (O.D.) and female threads on the surface of inside diameter (I.D.). When used in piping connection, its O.D. screws into the larger-diameter pipe with female threads and its I.D. screws into the smaller-diameter pipe with male threads, thus, makes a reduction in line …

Technical Drawing The ASME B16.11 plug, like a cap, is designed to close off the end of a run of pipe. It is manufactured for screwed fittings with male threads and are screwed into the end of a pipe to create a seal. As illustrated in the drawing above, plugs can be further classified according to the head style: square …

Drawing & Function The ASME B16.11 street elbow is a 90° elbow with one end externally threaded (male NPT) and the other end internally threaded (female NPT). The male NPT end is to connect with a female-NPT screwed pipe while the female NPT end is to connect with a male-NPT screwed pipe. It changes the flow direction by an angle …
