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.

Slip on flange also named as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom.

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.

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.

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.

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.

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.

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.

Threaded flange is a non-welded flange that is made by processing the inner hole of the flange into pipe threads and matching with the threaded pipe to achieve connection. The connection method is to match the inner hole of the flange with the thread on the pipe, and then rotate and connect them together.

150LB slip on flange is the lowest pressure flange in all pressure flanges.ASME B16.5 forged flange is manufacted according to American Standard.Pressures for flanges have 150LB,300LB,600LB,900LB,1500LB,2500LB.

Class 150 WN flange is the lowest pressure flange in all the flanges,langes also have many pressures:CL300, CL600, CL900, CL1500, CL2500.ASTM A105 is the matal standard for forged flanges and fittings.

ASTM A182 F304 spectacle blind is more often used than carbon steel spectacle blind as its great anti-corrosive function.ASME B16.48 is the standard of spectacle blinds.The two components have different functions in the piping system.

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.

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.

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.

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.

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.

1500 LB SO flanges are belong to high pressure flanges.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flange dimension has a very large range to meet different demands.

What is a blind flang,what about its specification and advantage.

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.

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.

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.

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.

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

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.

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.

150LB SO Flange is the lowest pressure flange in flanges.High Pressure Forged Flange have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

600LB SW flanges can socket with the flanges and then welded with the pipes.Large diameter flanges can be series A and series B.ASME B 16.47 A & B are standard for large diameter flanges.
