Product Description

ASME B16.5 Slip on/So Forged Flange DN500 ASTM A105 A182 F304L Forging SO Flange

Solution Description

Slip-on flanges are set up on pipes by slipping on the flange bore over the outdoors diameter of pipe and securing it to the pipe by fillet welds. There is no full penetration weld between the pipe and slip-on flanges, therefore the joint are not able to be subject matter to radiography. A slip-on flange can have a single stuffed weld or double fillet weld. As per para 328.5.2 of ASME B31.3, if slip-on flanges are solitary welded the weld is required to be produced at the hub. Exactly where two welds are needed, one fillet weld is manufactured at the hub of the slip-on flange and the CZPT fillet weld is manufactured at the inside of diameter of the flange close to the flange confront. The position of pipe within the slip-on flange need to be such that the fillet weld can be carried out with out damaging the flange face.The measurement of fillet weld on the within of flange is equivalent to the lesser of pipe wall thickness or 6mm.
ASME B31.3 provides three possibilities of weld details for double-welded slip-on flanges. A slip-on flange shall be double-welded as revealed in Fig. 328.5.2B of ASME B31.3 when the support is

  • matter to serious erosion, crevice corrosion, or cyclic loading
  • flammable, harmful, or harming to human tissue
  • beneath severe cyclic situations
  • at temperatures underneath −101°C (−150°F)

The use of slip-on flanges need to be prevented the place several large temperature cycles are predicted, notably if the flanges are not insulated.

Advantages of slip-on flanges
Slip-on flange is a chosen flange for numerous purposes thanks to the pursuing:

  • lower procurement price
  • less talent required for putting in owing to use of fillet welds instead of full penetration butt weld
  • weld end preparing not essential on pipe ends
  • diminished accuracy in the cut size of pipe

Limits and negatives of slip-on flanges

Though the original procurement cost of slip-on flange is minimal, slip-on flange has the subsequent drawbacks:

  • flange set up requires the use of two fillet welds
  • non-harmful evaluation is essential on two welds which helps make the installation value around the very same as weld neck flange
  • slip-on flanges are unsuitable for cyclic loading as mentioned over
  • slip-on flanges are not CZPT in dimensions 2½ inches and in excess of in course 1500 score and not CZPT in any size for class 2500 rating
  • the toughness of a slip-on flange is significantly less than that of a weld neck flange due its design and style (significantly less reinforcement in the hub) and installation approach (fillet weld as an alternative of butt-weld)
