High Pressure Pipe Flanges F304 Forged Steel Flange

A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange.

Standards and application Referred for WN flange and application

The bore of the slip on will give ample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.Slip-On flanges are commonly lower in price than weld-neck flange.However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation.

This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The 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.

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.

Class 600 WN flange is a high pressure flange.Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.ASME B16.5 is the American Standard for flanges.Flanges have five face types:RF RTJ FF MF TG.

The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping). 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.

ASME B16.5 SW flange is belong to American Standard for forged flanges,this kind of flange are been used all over the word.Forged flanges are high pressure flanges,the commonly used classes are CL 300,CL 600 for forged flanges.Stainless steel flanges always more expensive than other flanges because of the stainless steel has better functions.

The common material grade of stainless steel ASTM A182 contains F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

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.

A182 F304 forged flanges are stainless steeel flanges,ASME B16.5 SW flanges are socket weld flanges following American Standard specifications.

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.

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.

Materials of WN Flanges

Welding neck flange benefits

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.

Slip on flange is also called SO flange.This flange can slip onto the pipes and welded with the pipes.Shanghai Zhucheng is a forged flanges supplier who supply high quality flanges for years.

What is a weld neck flange and its specification?

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.

The spectacle blind flange is named because its shape resembles the number “8”. One end is a blind and the other end is an iron ring. However, the diameter of the throttling ring is the same as the diameter of the pipe and does not play a throttling role. This design makes the spectacle blind flange uniquely flexible and practical in the pipeline system.
