What Is B16 34

The ASME B16. 34 specification covers pressure and temperature ratings for forgings, castings, plate, bar, and tubular products. 34 charts show the max allowed pressure for a material depending on the product rating and the process temperature (the higher the temperature, the lower the pressure at a given rating).

What B16 5?

ASME B16. 5 standard covers Steel Pipe Flanges and Flanged Fittings from NPS 1/2 through NPS 24 Metric/Inch in pressure class 150 to class 2500. It covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.

What B16 10?

B16. 10 – Face to Face & End to End Dimensions of Valves – ASME.

What is ASME B16 11?

ASME B16. 11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.

What is ASME B16 9?

ASME B16.9, 2018 Edition, October 29, 2018 – Factory-Made Wrought Buttwelding Fittings. General. This Standard covers overall dimensions, tolerances, ratings, testing, and markings for factory-made wrought buttwelding fittings in sizes NPS 1∕2 through NPS 48 (DN 15 through DN 1200).

What is face-to-face dimension?

The face-to-face dimension for flanged Valves is the distance between the extreme ends which are the gasket contact surfaces. The distance between the extreme ends is described as the end-to-end dimension and applies to flanged Valves like: Ring Joint, large or small female and large or small groove.

What is api594?

API Std 594, Check Valves: Flanged, Lug, Wafer, and Butt-welding, is a standard developed and published by the American Petroleum Institute (API) that covers the design, materials, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and testing requirements for Type “A” and Type “B”.

What is API 6D?

The API 6D is the specification for Pipeline Valves. It is the primary standard based on the ISO 14313 that specifies the requirements of valves and offers suggestions for the design, manufacture, inspecting, and notation of check, ball, plug, and gate valves in pipework systems.

Is ANSI and ASME the same?

ANSI establishes and accredits performance and quality standards for products and services in a wide variety of sectors, while ASME is primarily focused on boilers and pressure vessels.

What is a half coupling?

Half Coupling is used for small bore branching from a vessel or large bore pipe. It can be threaded or socket type. It has a socket or thread end on only one side. A socket weld half coupling can be directly welded to large bore pipe, to make a branch connection.

What is ASTM A 105?

ASTM A105 is a standard material specification for forged carbon steel piping components including bolts, nuts, studs and other fasteners to standard or custom dimensions, for use in ambient and higher temperature service in pressure systems.

What B16 1?

ASME B16.1, 2020 Edition, November 9, 2020 – Gray Iron Pipe Flanges and Flanged Fittings Classes 25, 125, and 250. This Standard covers Classes 25, 125, and 250 Gray Iron Pipe Flanges and Flanged Fittings. It includes. (a) pressure–temperature ratings. (b) sizes and method of designating openings of reducing fittings.

What is ANSI pipe?

“ANSI class” is the designation for pressure-temperature ratings of pipe flanges. Much like other objects and processes that have found themselves called ANSI something (e.g. ANSI C or ANSI A Paper), the ANSI portion of the name comes from being specified in an American National Standard.

What is ASTM A403?

ASTM A403 specification covers stainless steel pipe fitting components used in pressure systems. These pipe fittings are manufactured in seamless and welded type. The material for fittings consist of seamless or welded piping products. These austenitic steels give good resistant to stress corrosion cracking.

What type of valve is a butterfly valve?

The butterfly valve is classified as a quarter-turn valve. It works like a ball valve for quick shutoff, but unlike a ball valve, the butterfly valve can also open and close incrementally. This difference means that the disc is always present in the flow and allows for a drop in pressure.

What is a long pattern valve?

Long pattern valve: Distance between end to end flange is wider (so called long pattern). And designed as per API 600 standard. DIFF: Diff between both pattern is not only end to end distance but the standard according to which valve is designed.

What are gate valves made of?

Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber.

What is valve API?

An overview of the American Petroleum Institute – API – valve standards. Describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs. ANSI/API STD 594. Check Valves: Flanged, Lug, Wafer and Butt-welding.

What is the difference between API 600 and API 602?

For users of gate valves, API 600 is the key document. It details all design and material criteria. This specification covers the same details small forged gate valves that API 600 does for larger valves. API 602 further gives dimensions for extended body valves which are used extensively in industrial facilities.

What is swing check valve?

A swing check valve has typically a globe style valve body with a hinged valve disc, to block reverse flow. The valve seat is typically full-ported in an angled our straight thru. Flomatic® offer several different type of swing check valves for water and wastewater applications.

Is API 6D fire safe?

They are fire safe tests for valve 6D and 6A. API 6A is the standard for wellhead and tree equipment safety valves, corresponding to ISO 10423 and API 6D is the standard for line ball valves, corresponding to ISO 14316.

What is API 6A standard?

API Spec 6A is an International Standard that specifies requirements and gives recommendations for the performance, dimensional and functional interchangeability, design, materials, testing, inspection, welding, marking, handling, storing, shipment, purchasing, repair and remanufacture of wellhead and christmas tree.

What is API standard code?

API specifications are recommended practices developed based on insight gleaned from the petroleum and petrochemical industry – which makes sense given that API stands for American Petroleum Institute. API standards are intended to encourage safety in the oil and natural gas industries specifically.
