What are slip on flanges

What are slip on flanges Slip on Flanges Slip On flanges or SO flanges are designed to slip over the outside of pipe, long-tangent elbows, reducers, and swages. The flange has poor resistance to shock and vibration. It is easier to align than a weld neck flange. This flange is ideal for low pressure applications since the strength when under internal pressure is about one third that of a weld neck flange. This flange has a raised face. Slip On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher life expentancy than slip-on flanges under duress. The slip on flange is positioned so the inserted end of the pipe or fitting is set short of the flange face by the thickness of the pipe wall plus 1/8 of an inch, which thus allows for a fillet weld inside the SO flange equal without doing any damage to the flange face. The back or outside of the slip-on flange or SO flange is also welded with a fillet weld. Materials used: Common materials used are as follows: Stainless steel Brass Steel Alloy Steel Aluminum Plastics Titanium Monels Carbon steel Alloy titanium etc. 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: 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 Related News What are the factors affect flanges price？Let’s look Post time: Jun-02-2022 Materials Used Key Features Advantages Buying Tips Factors to consider before buying slip-on flanges are as follows: Size Design Standard Material Normal Pressure Face Type Flange Diameter Flange Thickness Durability Corrosion resistant
