Class 600 WN Flange ASTM A350 LF2

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

Usage of a weld neck flange

Class 600 WN flange is a high pressure flange used in piping system.ASTM A350 LF2 is represents to low temperature carbon steel in American Metal Standard.Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.

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.

Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

Equal tee is one type of pipe fittings, also called straight tee which means the branch diameter is same with the main pipe (Run pipe) diameter.

Stainless steel socket flanges are installed during pipeline construction and connected to another pipeline through bolts to achieve a tight connection of the pipeline.

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.

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.

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.

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.

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.

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.

What is a Spectacle Flange and what about its specification and advantages.

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.

Stainless steel lap joint flange is a flange connection component, which consists of a flange, a flanged short section or a butt welding ring. Among them, the flange is made of stainless steel, which has good corrosion resistance, heat resistance and other properties.

Common material grade for stainless steel flange: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

Classification of weld neck flange

What is a Blind Flange,what about its specification and its advantages.

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

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.

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.

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.

What is a Weld Neck Flange and its 2 different shapes

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.

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.
