Forged Steel Pipe Flanges Carbon Steel Slip On Flange Dimension

Some information abou SO Flange.

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.

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.

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.

What is a weld neck flange and what about its dimensions?

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

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.

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.

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.

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.

Classification of weld neck flange

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 .

It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering. Similar to welding neck flange, the slip on flange conforming to ASME B16.5 may generally be furnished with three facing types: raised face (RF), flat face/ full face (FF), or ring type joint (RTJ).

A182 F304 slip on flange include flanges, bolt holes and sealing surfaces. The flange is a flat ring structure with an outer diameter larger than the outer diameter of the pipe connected to it. The bolt holes are evenly distributed on the flange and are used to install bolts to connect two flanges.

Stainless steel flange is popular because stainless steel has great anti-corrosive function.Flanges can be many types:WN,SO,SW,THD,LAPJ,BL.These flanges use different connections to connect with the pipes.Shanghai Zhucheng is a high quality manufactory who can supply all types of flanges.

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.

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.

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.

Standards and application Referred for WN flange and application

Slip on flange can be made by forging, steel cutting, casting and etc. Among these manufacturing types, the forging type gains the best quality and also the most common use.

Slip on flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.

A182 F316‌ lap joint flange uses flanges, steel rings, etc. to put the flange on the pipe end, so that the flange can move on the pipe end. The steel ring or flange is used as a sealing surface, and the flange is used to press them tightly.

Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.

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.

Class 150 F316 slip on flange is a common pipe connection element, mainly made of stainless steel material, through slip on and pipe or other flanges are connected. slip on flange is generally composed of flange plate, bolt hole and sealing surface.

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.

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.

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.
