DN15-DN600 Slip on flange RF FF 1500LB ASME/ANSI B16.5

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.

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.

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.

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 flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are seven flange classes ranging: #150, #300,#400, #600, #900, #1500 #2500.

300LB Stainless Steel Flange is always be chosen because of the excellent anti-corrosive function,SS316 is one of commonly used grade for stainless steel.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

Stainless steel lap joint flange is a flange connection component, which consists of a flange, a flanged short section or a butt welding ring. Among them, the flange is made of stainless steel, which has good corrosion resistance, heat resistance and other properties.

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. 

WN flanges is the most popular type of flanges.ASTM A182 F304 is a American standard grade of stainless steel.The other popular grade is A182 F316.ASME B16.5 forged flanges inculding WN flange,SO flange,SW flange,THD flange,LAPJ flange,BL flange.All types of flanges have pressures:150#,300#,600#,900#,1500#,2500#.

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.

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

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

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 .

What is a Weld Neck(WN) Flange and what about its specification and advantages.

High pressure flange carbon steel material: ASTM A105 / A105N, ASTM A350 LF2/LF3, ASTM A694 F42 / 46 / 56 / 60 / 65, P235GH, P265GH, P280GH, P355GH

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.

600LB Silp On (SO) Flange can slip on the pipes and welding with the pipes.Stainless steel flange are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

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

Welding neck flange benefits

300LB THD flanges are one types of flanges.Other types of flanges are WN,SO,SW,LAPJ,BL.ASTM A182 F316 flanges are popular in many corrosive environments because of the excllent corrosion resistance.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

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.

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.

ASTM A182 F316 is a popular grade for stainless steel in American Standard.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

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.

An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.
