ASTM A350 LF2 Blind Flange

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.

Welding neck flange benefits

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.

The connection method of A182 F11 socket flange is to insert the pipe into the socket of the flange, and then seal it with welding or use a sealing gasket. This connection method is relatively strong and can adapt to the thermal expansion and contraction of the pipe to a certain extent.

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

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.

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 pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.

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.

Reducing pipe (reducing nipple) is a pipe fitting used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

18in CL600 WN flange is belong to large dimension flanges.ASME B16.5 is standard for forged flanges.Forged flanges have important functions in high pressure enverionments.

ASTM A350 LF2 is a low temperature carbon steel material, mainly used to manufacture flanges and other connectors. This material has good low temperature performance and corrosion resistance, and is suitable for use in low or ultra-low temperature environments.

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.

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.

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.

Usage 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.

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.

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.

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.

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.

Socket Weld Flange contain a shoulder on the flange inside that acts as a guide to set the depth at which the pipe is welded to the flange.

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 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.

CL 600 slip on flanges are commonly used type of flanges.ASTM A182 F316L is a popular grade for stainless steel.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel flanges can used over 50 years.

ASTM A105 threaded fittings is commonly used carbon steel grade which is used to manufacture forge piping components such as forged fittings and flange of small diameter piping, generally for piping whose nominal diameter is NPS 2 or smaller.

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.
