Carbon Steel ASTM A105N Forged Flange Slip On Flange Manufacturer ASME B16.5

The ASME B16.5 Weld Neck Flange is a welding-type flange cast or forged integrally with the tapered neck. It is then buttwelded to the piping system. The ASTM A182 SS WNRF Flange is made of austenitic steel consisting of 18% chromium and 8% nickel, and it is this composition that makes the flange strong and highly resistive to corrosion. 

A105 WN flange is a carbon steel flange according to ASME B16.5.STD is represents the thickness of the flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG.

A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are six flange classes ranging from #150 to #2500. Governed by B 16.5 standards, the ASME B16. 5 Class 300 Flange provides a pressure capacity of 300Lb.

P280GH weld neck flange refers to a flange connection method that uses P280GH material as the base material and forms one or more layers of P280GH material welding layers on the flange surface through the butt welding process to improve the flange’s high temperature resistance, high pressure resistance and corrosion resistance.

The descipton ,specification ,and advantages of a weld neck flange.

SW flange can be used in many applications in piping systems.SW Flanges are forged flanges.Socket weld flange has many classes:150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB.Stainless steel flanges have better functions than other flanges which made from carbon steel or alloy steel.

What is a weld neck flange and its specification?

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.

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.

Stainless steel weld neck flange is a part widely used in pipeline engineering. The diameter and wall thickness of the pipe at the interface end are the same as the pipe to be welded, and the connection of the pipe is realized by welding.

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.

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.

Usage of a weld neck flange

Slip on flange also named as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom.

It is used to insert the pipe into the inner hole of flange, as the flange inner diameter is little bigger than the pipe’s outer diameter, pipe and flange could be connected by lap welding at the top and bottom of the flange. 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.

18in CL600 WN flange is belong to large dimension flanges.ASME B16.5 is standard for forged flanges.Forged flanges have important functions in high pressure enverionments.

There are Weld Neck Flange ( WN),Slip-on Flange (SO), Threaded Flange (THD),Socket Weld Flange (SW),Blind Flange (BL),Lap Joint Flange (LAPJ),Plate flange (PL). We also supply alloy steel flanges and stainless steel flanges .

Class 600 WN flange is a high pressure flange used in piping system.ASTM A350 LF2 is represents to low temperature carbon steel in American Metal Standard.Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.

Welding neck flange benefits

Stainless steel lap joint flange is always used with lap joint stub end (a kind of butt welded fitting).A182 F304 forged flanges have great anti-corrosive function,flanges in this material have longer using years than other materials.

Flange provides a long tapered hub for welding to pipes , it is used in high pressure systems and suitable for both cold and hot temperatures.

Socket weld flange can socket with the end of pipe,and welding on the pipe.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

150 LB blind flange is a flange similar to plug.BL flanges are used to close the pipe system.ASTM A105 forged flange is carbon steel flange in American Matel Standard.

ASME B16. 5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.

ASTM A105 threaded fittings is commonly used carbon steel grade which is used to manufacture forge piping components such as forged fittings and flange of small diameter piping, generally for piping whose nominal diameter is NPS 2 or smaller.

ASME B 16.5 2 inch socket weld (SW) flanges are used for small size and high pressure pipe systems.Stainless steel flanges are more expensive than carbon steel flanges because of the better functions.The pressures could be chosen:CL150,CL300,CL600,CL900,CL1500,CL2500.

There are various material grade for ASTM A182 stainless steel flange: F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

Steel Flange Fittings connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.
