Forged welded neck flanges DN 1/2″-48″ ASTM A105 A350 A182

ASTM A182 F316 Threaded Flange is a flange manufactured according to A182 standard, and its connection method is threaded connection. It is a commonly used connector in pipeline systems, used to connect pipelines, valves, pumps and other equipment, so that fluids can be smoothly transmitted within the system.

Welding neck flange benefits

The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping). 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.

What is a SW flange and what about its specification.

A swage nipple is something similar to that of a reducer but it is used to join the butt welded pipe with a socket welded or screwed pipe.Like the reducer,swage nipple is also available with two variations:concentric swage nipple and eccentric swage nipple.The swage nipple generally adopts the MSS SP-95 or the BS3799 Standard.

A WN / weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

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

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

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.

Blind flanges are used to seal the end of piping systems or pressure vessel openings.

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.

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

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.

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

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.

P280GH weld neck flange refers to a flange connection method that uses P280GH material as the base material and forms one or more layers of P280GH material welding layers on the flange surface through the butt welding process to improve the flange’s high temperature resistance, high pressure resistance and corrosion resistance.

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, 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.

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.

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).

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.

Some information abou SO Flange.

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.

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.
