Top 6 Common Flange Types

 The most used flange types according to ASME B16.5 are: Welding Neck flange, Slip On flange, Socket Weld flange, Lap Joint flange, Threaded flange and Blind flange.

Slip-on Flanges - are all bored slightly larger than the O.D. of the pipe.
Weld Neck Flanges - is normally referred to as the high hub flange.
Blind Flanges - available to seal both pipes and vessels
Lap Joint Flanges - available in a range of sizes to pair with stub end fittings for easy dismantling
Threaded Flanges - engineered to fit pipes with external threads for weld-free fits
Socket-weld Flanges - designed with a socket fit and top weld for ideal inner flow in pipe systems

Custom pipe flanges can be manufactured from a wide variety of materials and material grades.

Carbon Steel flanges - the main material is carbon steel flange or end flange connectors.
Stainless Steel flanges - F304 F304L F316 F316L 316Ti, Copper etc.
Alloy Steel flanges- accord to ASTM A182 F1, F5a, F9, F11, F12, F22, F91
Forged flange- are perfectly finished with precision using the latest machinery.
Large diameter flange -used to connect or to block off two very large diameters sized pipes.

What is a Pipe Flange?

图片
  Flanges  is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pump, valve, pressure vessel or any other piece of equipment. Stainless Steel Flanges And Carbon Steel Flanges & Alloy Steel Flanges provide easy access for modification, cleaning or inspection. A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange . This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance. Most common specification for carbon steel and stainless steel flange is ANSI B16.5 / ASME B16.5.  Metal flanges are commonly used for industrial, commercial, and institutional application. Steel pipe flanges are available in variety of styles and pressure classes. Metal flanges are classified from 150 to 2500 # rating.

Corrosion Resistance Of 2205 Duplex Steel pipe

  2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.We have wide range of sizes in our stock of  2205 Duplex Stainless Steel Pipe  & 2507 Super Duplex Stainless Steel tube,S31803 Welded Pipes Tubes . 2205 steel has excellent corrosion resistance and is superior to grade 316, performing well in most environments where standard austenitic grades may fail. 2205’s low carbon content gives the grade a high resistance to intergranular corrosion and has better resistance to uniform, pitting and crevice corrosion due to its high chromium and molybdenum content.  As 2205 is a duplex stainless steel, the grade is also less sensi
