Slip On Flange Forged Flanges Supplier

What is a Blind Flange?Where are Blind Flanges Most Commonly Used?

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.

ASTM A182 F304 600LB slip on flanges are very popular type of flanges because of the excellent functions and high pressure.ASME B16.47 Series A & B are American Standard for large dimension flanges.According to ASME B16.47 Series A& B,the smallest size of flanges is 22 in.

Class 300 LAPJ flanges are used with lap joint stub end.The pressures for ASME B16.5 forged flanges including 150LB,300LB,600LB,900LB,1500LB12500LB.

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.

Face Type of a WELD NECK flange

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.

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.

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.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and then Flange pads are added between the flange plates and fastened together with bolts to complete the connection

Carbon steel flange, that is, the body material is carbon steel plate or end flange connection. The flanges containing carbon steel are called carbon steel flanges. Common materials are carbon steel ASTM A105 / A105N, ASTM A350 LF2/LF3, ASTM A694 F42 / 46 / 56 / 60 / 65, P235GH, P265GH, P280GH, P355GH. Besides carbon steel flanges, we also supply alloy steel flanges and stainless steel flanges .

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.

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.

Socket Weld Half Couplings is utilised in various applications in order to provide a torque free sealing and a leak free connection. Socket weld coupling is a very short section of pipes with socket bore at both ends or one end, but both can afford high pressure of 3000#, 6000#, 9000#. The Socket Weld Half Coupling are often directly welded to the run pipe, to form a branch connection.

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.

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.

Duplex Stainless Steel: ASTM A182 F51, F53, F44

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#.

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.

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.

Standards and application Referred for WN flange and application

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.

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

l. Large diameter flat welding flange has less high-pressure suitability compared to its weld neck counterpart. The basic ring style is suitable for the occasion of low pressure. The butt weld category of the flange is known as a weld neck flange. It suits the occasion of high temperature and pressure as defined in the ASME B16.47 code. Large diameter flanges are widely popularized and used in the sewage treatment industry, wind power industry, chemical industry, and machinery industry.
