PED Steel Flanges / Weld Neck Flanges / ASTM A 182 Stainless Steel WNRF Flanges

 

Weld Neck Flanges Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications. We are a fast growing organization, engaged in manufacturing, supply and export of welding neck flanges, industrial weld neck flanges and forged flanges. Our weld neck flanges are drilled with the wall thickness of flange having the same dimensions of pipe. Flanges for heavier pipes have smaller bore, while flanges of lighter pipes have larger bore. These weld neck flanges, industrial weld neck flanges, forged flanges are normally used for high-pressure, cold or hot temperature.

API Steel Flanges ANSI 150# / 300# Alloy Steel Slip on Flanges

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.

 

How to measure slip-on flanges?
Take the measurements of:

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

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
