CL600 Stainless Steel Slip On Flange ASTM A182 F316L

Stainless steel slip on flanges are popular type of flanges because of the great material and flexible applications.Pressures of flanges:CL150,CL300,CL600,CL900,CL1500,CL2500.ASTM A182 F316L and ASTM A182 F304 are both popular grades of stainless steel.

CL600 stainless steel slip on flange is a commonly used type of flanges,CL600 repersents pressure,it can also writen as 600LB,600#.ASTM A182 F316L is a popular grade of stainless steel according to American Standard.


The slip on flange is a simple and excellent alternative to a weld neck as it does not have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position of the flange. The bores of the slip on flange will give sample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.SO flanges are commonly lower in price than weld-neck flange.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.



  1. Low cost
  2. Saves space
  3. Reduces weight
  4. Anti leakage
  5. Good sealing performance



  1. In principle, pipes must always be welded first, and then fittings.
  2. Can not be combined with elbows and tees
  3. Can not guarantee no leakage.



They are mainly used for fluids at low pressure or with little risk of leakage. It is very common to find these flanges today in cooling water lines, firefighting water lines, low-pressure compressed air lines, and process lines for substances such as steam, oil, gas, condensates, etc.

Slip On Flanges VS Weld Neck Flange

Slip on flanges are more commonly found in lower pressure assemblies and become less utilized when a higher stress service calls for a superior connection to the piping assembly.Welding neck flange can provide more powerful service in mechanical stress environment Moreover, weld-neck flanges have a higher life expectancy than slip-on flanges under duress.
