Forged ASTM A182 F53 S32750 Flanges Slip On Pipe Flanges Orifice Size1/2'-24'

Key Features of Slip-On Flanges :

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.

Advantages of slip on flanges:

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

Most used pipe flange

Slip on pipe flange is suitable for the lower pressure, general temperature and normal circumstance pipelines. It is easy to install and with lower cost/price, has been most used in the common industries.

Slip-on Flanges

Slip-on Flanges have a lower initial cost than welding neck flanges because they require less accuracy in cutting pipe to length, and they provide a greater ease of alignment in assembly. However, their calculated strength under internal pressure is approximately 2/3's the strength of welding neck flanges, and their life under fatigue is 1/3 shorter. Slip-on Flanges are limited to 1/2" to 2½" sizes in 1500lbs standard.

Weld Neck Flanges

Weld Neck Flanges have a long tapered hub and gradual transition of thickness in the region of the butt weld joining them to the pipe. The tapered hub provides important reinforcement to the flange and resistance to dishing. This type of flange is preferred for severe service conditions resulting from high pressure, sub-zero or high temperatures.

Blind Flanges

Blind Flanges are used to blank off the ends of piping, valves and pressure vessel openings. Blind Flanges can handle high stress from internal pressure and bolt loading since the maximum stresses in the blind flange are bending stresses at the center.

Socket Weld Flanges

Socket Weld Flanges were developed for use on small size high pressure piping. With an internal weld, socket weld flanges are stronger and have greater fatigue strength than double welding a slip-on flange. Smooth bore conditions can be easily attained by grinding the internal weld. This flange is commonly used in chemical process piping.

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.

How to measure slip-on flanges?

Take the measurements of:

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