ASTM A182 F6a is a forged martensitic stainless steel with 13 wt. % chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys. The ASTM standard A182 describes the general set of specifications about several material grades.
What does ASTM A182 mean?
ASTM A182 is the standard of forged or rolled alloy-steel pipe flanges,forged fittings,and valves and parts material,it indicates the materials properties of different kinds of alloy steel. F347H is one of the steel grade in this standard. F means forged.
What is A182 flange?
ASTM A182 Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
What is ASTM A182 Gr F316?
ASTM A182 F316 is a forging material specification for 316 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.
What is ASTM A105?
ASTM A105 steel bar is a steel specification for low carbon forged components. Eaton Steel Bar Company stocks many diameters of A105 hot rolled steel rounds to meet the market demands. We supply A105 steel bar to various industries including oil & gas.
What is ASTM a312 stainless steel?
This specification covers seamless, straight-seam welded, and heavily cold worked welded stainless steel pipe intended for high-temperature and general corrosive service.
What is A182 F22 material?
UNS K21590: ASTM A182 (VO1. 01) Grade F22 is a low alloy steel containing nominally 2.25% Chromium. The alloy is widely used in the oil patch wellhead applications for connectors, hangers and block valves. Hardness levels up to 22 HRC are approved to NACE MR0175.
What is blind flange?
It is used to terminate the end of a piping system. The blind flange is basically a flange that does not have a hub or a bored center. Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern. Blind flanges can also be used to seal a nozzle opening on a pressure vessel.
What B16 11?
ASTM B16.11 is the standard used for the forged steel fittings which includes socket weld and threaded. fittings type. This standard is available in carbon steel, alloy steel and stainless steel materials. 45 and. 90 degree elbow, its size range is 1/2” to 4”, and the classes of the product are ranging in 3000, 6000.
What is F91 material?
ASTM A182 Gr. F91 Alloy Steel High Pressure Forged Fittings This is a low alloy steel with alloys less than 5%. Due to the chemical composition, people also call it as chrome moly alloy. F91 Couplings have highly strength to withstand high pressure. The low carbon content makes socket weld flanges easy to weld.
What is the difference between F316 and SS316?
The alloy for ASTM A182 F316 Stainless Steel Flanges contains nonferrous elements such as chromium, nickel & molybdenum as primary alloyants. The only difference between regular 316 stainless steel and A182 Grade F316L BLRF is that 316L has a lower content of carbon in its alloy.
What is CF8M stainless steel?
Stainless Steel SA-351 CF8M is a molybdenum bearing modification of CF8 Austenitic Steel alloy and is the cast equivalent of wrought AISI 316 stainless steel. The presence of molybdenum increases the general corrosion resistance and the resistance to pitting by chlorides.
What is SS316?
Stainless steel 316 (SS316) is an austenitic chromium-nickel stainless steel containing deliberate amount of molybdenum which increases general corrosion resistance and especially improves its pitting resistance to chloride ion solutions. Thus, SS316 is also known as “Mo-Added” version of SS304.
What does ASTM A106 mean?
ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures.
Is ASTM A105 stainless steel?
Certificate: ISO9001:2000 ,API.Product Description. Production: High quality stainless steel flange Type: WN/SO/PL/BL/TH/SW/LF Material: stainless steel: 321,201, F304 , F304L ,F316,F316L,316.
What is difference between A105 and A105N?
N means Normalization heat treatment,and A105 flange haves no heat treatment requirement. That means the A105N flange is one kind of A105 flange. But A105N flange have a better mechanical properties than regular A105 flange,better strength and better performance in low temperature service.
What is ASTM A312 pipe?
ASTM A312 pipe is the general use stainless steel pipe applied in different industries. It covers diameters from 1/8” to 30” and thickness from SCH 10S to SCH 80S. Common use material grades are TP304/304L, TP316/316L.
Is code for steel pipes?
1.1 This code covers the methods of laying electrically welded mild steel pipes of outside diameters 168.3 mm to 2 032 mm (as covered in IS 3589 : 1991), laid either above ground or underground for water supply.
What is F9 material?
Applications FORGING SPECIFICATION COMMON DESIGNATION MATERIAL SUFFIX A182 F22 2 1/4% Chrome Low Alloy Steel ASTM A217 Grade WC9 A182 F5/F5a 5% Chrome; 1/2% Moly, Medium Alloy Steel ASTM A217 Grade C 5 A182 F9 9% Chrome; 1% Moly, Medium Alloy Steel ASTM A217 Grade C12.
What is low alloy carbon steel?
Carbon steels are alloys of iron, carbon, manganese, and silicon. Low alloy steels are similar to carbon steels but have additional alloying elements like chromium, molybdenum, etc., to improve their heat treat response.
What 10CrMo9 10?
1.7380 | 10CrMo9-10 is a heat-resistant special structural steel. It is mainly used in boiler and apparatus construction for boiler drums and pressure vessels. The material is suitable for temperatures up to 550°C.
Where is blind flange used?
Blind flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel, in addition to allowing for easy access to the pipe in case work must be done inside the line.
Why is it called a closet flange?
In plumbing, a closet flange (also known as a toilet flange) is a pipe fitting (specifically, a type of flange) that both mounts a toilet to the floor and connects the closet bend to a drain pipe. The name comes from the term “water closet”, the traditional name for a toilet.
What are the different types of flanges?
Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance.
