What are slip-on flanges, and When do we use slip-on flange?

Slip-on flanges are available at a lower cost and hence preferred by several contractors. The product holds ample of strength and works even under fatigue conditions as that of the weld-neck flange. The slip-on flange can work well after attaching to the end of a pipe or pipe fitting. The product is fit in easily, or the end of the pipe is set back easily by the thickness of the pipe wall plus 1/8 of an inch. It allows easy installation without putting effort and damaging to the flange face. The outer side of the flange is welded with a fillet weld.

Features of Slip-on flanges 

These are flanges available at less cost. They have a low hub as pipe slips into the flange before performing welding. These slip-on flanges are easy to align welded, both internally and externally.

Types of Slip-on flanges 

There are various types ofSlip-on flanges, including the Slip-On Reducing Flange, raised face slip-on flange, and RTJ slip-on flange. The flange is applicable for reducing the line size and limitation of the space limitations. These flanges work along with the weld neck flange and reducer combination. They are useful when the flow is directed from the smaller size to the larger size. Slip-On flanges are welded internally and externally. The welding offers them the ability to prevent leakage and sufficient strength.

Uses of Slip-on flanges 

Slip-on flanges are primarily applicable for fluids working at low pressure. Also, these flanges work well with little chance of leakage. These flanges work well in cooling water lines, firefighting water lines, and low-pressure compressed airlines. Along with this, slip-on flanges are suitable in process lines to maintain the stream of steam, oil, gas, condensates, etc. These flanges are applicable for low pressure and higher temperature system.
