Flange Supplier Steel flanges

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. The bore of the slip on will give ample amount of space for the matching pipe.

Slip on flange is also called SO flange.This flange can slip onto the pipes and welded with the pipes.Shanghai Zhucheng is a forged flanges supplier who supply high quality flanges for years.

Slip ons in higher pressure classes are often made with the height of a lap joint for a better connection. If the hub height is not a concern and a lap joint is not readily available, customers will sometimes opt for a slip on made to a lap joint style with a machined hub.

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.

What is a Weld Neck Flange and its 2 different shapes

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.

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.

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

Steel Pipe Elbow is the most common pipe fitting that changes the direction of the pipeline. It plays a important role in the piping system.

Welding neck flange benefits

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

Slip-On flanges are commonly lower in price than weld-neck flange.However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation.

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.

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.

SW flange can be used in many applications in piping systems.SW Flanges are forged flanges.Socket weld flange has many classes:150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB.Stainless steel flanges have better functions than other flanges which made from carbon steel or alloy steel.

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.

ASTM A105 Forged Fittings 300# WN Flange
Size Range: 1/2″ – 48″/ DN15 – DN1200
Rressure rating: Class 150, 300, 600, 900, 1500, 2500lb

A flange is a category of gasket made to fix two sections of pipe together, or act as a removable plug at the end of a single pipe. 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.

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.
