ASTM A182 F60/F51 Slip on Flange ASME B 16.5/ASME B16.47 Duplex Stainless Steel Forged Flange

Flange (flange) connection is to put two pipes, fittings or equipment, first fix each to a flange disc, between the two flange discs, add flange pad, tighten with bolts together, complete the connection. Some pipe fittings and equipment have flanged, also belong to flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection easy to use, can withstand greater pressure. Flanged joints are widely used in industrial piping. In the home, the pipe diameter is small, and is low pressure, can not see the flange connection. If you are in a boiler room or production site, flanged pipes and equipment are everywhere.

Butt flanges, socket flanges, threaded flanges, loose flanges, slip flanges are available according to the connection.

Slip-on Flanges Slip-on flanges are a popular type of pipe flanges. These are type of flanges that slide over the end of piping and then welded in place. These flanges are ideal for lower pressure applications. These are easily fitted and welded into different pipes. Welding reduces fabrication costs of these pipes. These are available in wide variety of sizes and applications. Why slip on flanges are preferred to welding neck flanges? For many users, slip on flanges continue to be preferred to welding neck flanges because of the following reasons: On account of their initially lower cost. The reduced accuracy needed in cutting the pipe to length. The greater ease of alignment of the assembly. The calculated strength of slip-on flanges under internal pressure is approximately two-thirds that of welding neck flanges.

This slip on weld flange is according to JIS standard.It is a flange system made by Japan. This kind of flange include lots of specification,like SOP, SPH, Blind flange, plate flange, welded neck flange, etc.

Slip on weld flanges are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.

The material of the flanges is carbon steel. The flange can connecting pipes, valves, pumps and other equipment to form a pipework systems. It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings.

Take the measurements of:

• OD: Outside Diameter
• ID: Inside Diameter
• BC: Bolt Circle
• HD: Hole diameter

Some important features are as follows:

• One size fits all pipe schedules.
• Fabricators can more easily cut pipe to length for slip-on flanges.
• The smaller thickness of this flange allows for easier alignment of bolting holes.
• They are generally not preferred for high pressure temperature environments.

• Low cost installation
• Less time needed to spent on ensuring the accuracy of the cut pipe
• they are somewhat easier to align
• the slip-on flanges have low hub because the pipe slips into the flange before welding
• the flange is welded both inside and outside to provide sufficient strength
• they prevent leakage
