Slip On Flanges Manufacturer
SLIP ON FLANGES
Slip-on Flanges have bored with a diameter slightly larger than the pipe; this helps it to slide\slip over the pipe. This ANSI B16.5 SORF Flange is then welded inside and outside too, with fillet welding. Alloy Steel Slip On Plate Flanges are thinner compared to other ranges, cost-effective and are easy to use in fabricated applications. We supply Carbon Steel Slip-on Raised Face Flanges in both raised face and at faced designs, to industries like agricultural, fertilizers, pharmaceutical, textile and for general engineering purposes

Frequently Asked Questions About Slip-On Flanges
Are Slip-On flanges weaker than Weld Neck Flanges?
Yes, Slip-On flanges are generally calculated to have about two-thirds of the strength of Weld Neck flanges under internal pressure, and their life under fatigue is roughly one-third. Therefore, Slip-On flanges are favored for lower pressure applications and situations where precise alignment during installation is critical, as they can be easily slipped over the pipe and adjusted before welding.
Frequently Asked Questions
What are the primary advantages of Slip-On Flanges?Slip-On Flanges (SORF) are slid over the pipe before welding both inside and outside. They are lower in initial material cost than Weld Neck Flanges and require less precision when cutting the pipe, making them ideal for low-pressure systems and cooling water lines.
What pressure classes do you manufacture for Slip-On Flanges?We manufacture and stock ASME B16.5 Slip-On Flanges predominantly in 150# and 300# pressure classes, as they are not typically recommended for high-pressure or highly hazardous environments.
Can I get Stainless Steel 316L Slip-On Flanges for chemical pipelines?Yes! Gandhi Metal India supplies Stainless Steel grade 316L Slip-On Flanges specifically for petrochemical and chemical pipeline systems requiring enhanced corrosion resistance.
