Socket Weld Flange Stainless Steel Flanges

What is a Weld Neck Flange and its 2 different shapes

These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. 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.

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 .

Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. 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.

Usage of a weld neck flange

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.

A234 WPB blind flange is a type of flange widely used in pipeline systems. A234 is the standard number of the American Society for Testing and Materials (ASTM), and WPB indicates that this material is a carbon steel pipeline component for medium and low temperatures.

ASTM A350 LF2 Blind Flange is a common low-temperature carbon steel material, mainly used in the manufacture of low-temperature and high-pressure forged pipe fittings and flanges.

TOE means threaded at one end when translated. Thus, we can say that a nipple TOE is a nipple that has one threaded end.
In this case, we have the acronym TBE for “threaded both ends” which means threaded at both ends. In other words, this is the most typical type of nipple as described above for connecting two parts or fittings with female threading.

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.

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.

ASME B16.5 flange is a flange made accoding to American matal standaed.Class 150 WN flange is the lowest pressure of flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

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

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.

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.

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.

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.

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.

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

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.

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.

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.

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

Welding neck flange benefits

300 LB BL flanges are used to close the pipe system,it is similar to plugs and caps.Stainless steel 304 flanges are the most used stainless steel flanges as SS304 have excllent functions and reasonable price.

The main structural feature of the stainless steel lap joint flange is the loose connection. It consists of a flange body, a flange nipple and connecting bolts. The flange body and the flange nipple are loose fitting, and this structure allows the pipeline to expand and contract freely within a certain range.

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.

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.

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.
