Metal Flanges, Shape : Round

We are a major Manufacturer, Exporter & Supplier of Metal Flanges. The Metal Flanges offered by us are manufactured using high quality material like Stainless steel, Carbon steel, Brass, Aluminum, etc. Metal Flanges are used for attachment to another object. They are also used on the end of a pipe, steam cylinder, lens mount of a camera, train wheel, iron beam or I-beam (or a T-beam), etc. The use of Metal Flanges also makes the assembling or disassembling of pipes easily. The Metal Flanges we supply are high on demand because of the features like precision design, technical accuracy, corrosion resistant and long lasting service. Clients can avail the Metal Flanges from us in ferrous and non-ferrous finishes. Material Used

Stainless steel Carbon steel Brass Alloy steel

Bronze Aluminum PVC Cast iron

Features

High strength Corrosion resistance Durable Fine finish

Materials for flanges are usually under ASME designation SA-105 (Specification for Carbon Steel Forgings for Piping Applications). SA-266 (Specification for Carbon Steel Forgings for Pressure Vessel Components) orSA-182 (Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings,Valves and Parts for High-Temperature Service). In addition, there are many "industry standard" flanges that in some circumstance may be used on ASME work. Types of Reducing Flanges

• Welding Neck
• Slip-On
• Threaded

Uses of Reducing Flanges

• Reducing flanges are a little easier to bolt up than non-reducing flanges.
• They provide the most perfect solution when you need to connect different size flanges.
• These flanges are available in all types and pressures.
• Reducing flanges are fixed by welding, gluing or clamping flanges of equal dimensions provided with different connecting pieces.
• They offer the simplest and least expensive method of mating two different sized flanges.

Flange Size : There are available flange sizes and grades for all standard pipe wall thicknesses and pressure ratings. Flange Specification and Identification All flanges should be stamped for identification on the outside diameter of the base for east identification with :

• Nominal pipe size (NPS).
• Pressure rating (150 lb., 300 lb., etc.)
• Face designation - the machined gasket surface.
• Bore - the nominal pipe size (NPS).
• Material designation
• Ring gasket number - used for ring joint flange.
• Heat number of code - the batch number used when forged and tested.
