stainless steel pipe flanges China SS Flange Manufacturer

Stainless steel spectacle blind has better anti-corrosive function than other material of spectacle blinds.ASME B 16.48 is a commonly used standard for spectacle blindThe joint face can be RF (Raised Face), FF (Flat Face), RTJ (Ring Joint),it is depend on the type of flanges.

The slip-on flange is a simple and excellent alternative to a weld neck as it does not have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position of the flange. The bore of the slip on will give ample amount of space for the matching pipe.

A105 FF slip on flange is a commonly used pipeline connection element, mainly made of carbon steel, and connected to pipelines or other flanges by flat welding. The structure of the slip on flange is relatively simple.

It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering. Similar to welding neck flange, the slip on flange conforming to ASME B16.5 may generally be furnished with three facing types: raised face (RF), flat face/ full face (FF), or ring type joint (RTJ).

1500 LB SO flanges are belong to high pressure flanges.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flange dimension has a very large range to meet different demands.

Class 1500 SO flange Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG. Slip on flanges can slip on the pipes and welding with the pipes.

Stainless steel socket flanges are installed during pipeline construction and connected to another pipeline through bolts to achieve a tight connection of the pipeline.

What is a Socket Weld Flange,what abut its specification and advantages

150LB SO Flange is the lowest pressure flange in flanges.High Pressure Forged Flange have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

Threaded nipple is a short piece length of pipe or tube. Its size is specified according to the length of this section of pipe and the diameter. It can be with threaded or flat ends. And both ends can be the same or different.
There are two shape : threaded one end (TOE) and threaded both end ( TBE).

A weld neck flange is a type of flange that connects, seals, and changes the direction of a pipe in a pipe system by butt-welding the flange to the pipe. The neck of the weld neck  flange matches the outer diameter of the pipe, providing a good welding interface during welding to ensure the strength and tightness of the connection.

A105 Lap Joint flanges are made by using flanges, steel rings, etc. to put flanges on the pipe ends, and the flanges can move on the pipe ends. The function of the flange is to press them tightly. Because they are blocked by the flanges, the Lap Joint flanges do not contact the medium.

The equal cross is one kind of the pipe cross,  the equal cross means all the 4 ends of the cross are in same diameter.
The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters.

Class 150 WN flange is the lowest pressure flange in all the flanges,langes also have many pressures:CL300, CL600, CL900, CL1500, CL2500.ASTM A105 is the matal standard for forged flanges and fittings.

There are varies advantages of stainless steel flange:
Resistant to corrosion and staining
Low maintenance
Bright familiar luster
Steel Strength

Many times a nozzle will be blanked off with a blind flange for pressure tests in a plant, or simply because the customer does not need all the nozzles that were supplied on the tank.

DN150 SW flange is a 6in flange used to socketed with the pipes and then welding on pipes.CL150 forged flange is the lowest pressure flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

Slip ons in higher pressure classes are often made with the height of a lap joint for a better connection. If the hub height is not a concern and a lap joint is not readily available, customers will sometimes opt for a slip on made to a lap joint style with a machined hub.

A flange is a category of gasket made to fix two sections of pipe together, or act as a removable plug at the end of a single pipe. All flanges are round disks with holes for bolts around the rim, but the commonalities end there. a projecting flat rim used for strengthening or attachment.

Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

ASTM A350 LF2 is a low temperature carbon steel material, mainly used to manufacture flanges and other connectors. This material has good low temperature performance and corrosion resistance, and is suitable for use in low or ultra-low temperature environments.

Stainless steel flange, also called SS flange, it means the material of flange is stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.

ASTM A182 F316 Threaded Flange is a flange manufactured according to A182 standard, and its connection method is threaded connection. It is a commonly used connector in pipeline systems, used to connect pipelines, valves, pumps and other equipment, so that fluids can be smoothly transmitted within the system.

Alloy Steel: ASTM A182 F11 / 12 / 5 / 9 / 91 / 92
Stainless Steel: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L, 1.4404, 1.4437.

A105 Class 150 Carbon steel blind flange is a blind plate made of carbon steel material, which is connected to the flange in the pipeline system to prevent the passage and leakage of fluids, gases and other media.

A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

A swage nipple is something similar to that of a reducer but it is used to join the butt welded pipe with a socket welded or screwed pipe.Like the reducer,swage nipple is also available with two variations:concentric swage nipple and eccentric swage nipple.The swage nipple generally adopts the MSS SP-95 or the BS3799 Standard.
