This Slip-On Flange is often chosen over Welding Neck Flanges because of its lower initial cost and is widely used because it requires less accuracy in cutting pipe to length and permits alignment of bolt hols and squaring of flange faces with less difficulty.Refacing to repair warpage or weld spatter damage can be eliminated by the construction shown here if care is used when welding.Slip-On Flanges areMetal Pipe Flange - Pipe Fitting Weld neck - Slip on Conclusions Standard weld neck,slip on,blind etc.flanges are covered by standard B16.5 for sizes up to 24 nominal pipe.Sizes 26 and bigger are covered by B16.47 series A or series B for weldneck and blind flanges.Series A flange is heavier,thicker and cost more whereas series B flange has more bolt holes and is lighter cheaper than My best guess would be ASME B31.3.Try Fig.328.5.2B (1999 ed) Richard Schram Mechanical Integrity Specialist Pharmacia Global Supply Arecibo-P.Riapiguy I think I know the answer but will ask anyway.Where can I find the stds you refer to?

Richard Schram Mechanical Integrity SpecialistThe inside weld may or may not be required,depending upon what Code you are constructing the pipe in accordance with,and the service conditions.In my 20 years working as a pipefitter in a union local,it has always been standard procedure to backweld the inside of a slip-on flange to thJerry just from a commom sense point of view I agree with your standard procedure.Hi tomd87vr,I wouldnt dare to think about a possibility to mount a loose type (slip on) flange with outside welding only.You may see on the BoilAs I suggested before,you should look at the relevant code.ASME B16.5 is not a code. It is a component standard and it does not have requirementGo with a double fillet weld,with the weld legs => the pipe wall thickness.

Slip-on flanges are designed to slide over the outside diameter of the pipe to which it will be welded.These flanges are attached to the pipe by fillet welding at the hub and at the end of the pipe inside the flange.Slip On Flange - Introduction and Specifications OctalsteelSlip on flange also named as SO flange.SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe.They connect to the pipe through a fillet weld at the flange top and bottom.It is used to insert the pipe into the inner hole of flange,as the flange inner diameter is little bigger than the pipes outer diameter,pipe and flange could be connected by lap welding at the topSlip On Flange SO Flange Information China Hebei Slip on flange,as the meaning of name,is a flange slipping on the pipe or fitting when connection.The pipe should be insert the flange inner bore,and leave a bit distance from the face of the flange to make sure it will not effect the sealing of two flanges.
Slip on Flange Dimensions Class 150 to Class 1500 Slip on flange dimensions are covered in ASME B16.5 which covers Pipe Flanges and Flanged Fittings for size NPS ½ to 24 for above NPS 26 to 60 it should be as per ASME B16.47.During a dimensional inspection of slip on flange,you should check for Outer Inner Diameter of bodySlip on Flange Placement Rules - ASME (mechanical) Code ·creates a sealing face similar to that of a weld neck flange.This flange type provides the optimal sealing surface for an ASME compliant spiral wound gasket,as well.SLIP-ON FLANGE Slip-on flanges are also built with a bore slightly larger than the outside diameter of the pipe,but,unlike a socket flange,this larger bore is the same Slip-On Flanges Slip On Pipe Flange Texas FlangeThe 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 bore of the slip on will give ample amount of space for the matching pipe.
Jan 22,2021·Flat welded flanges with neck,also referred to as slip-on welding flange,SO flange for short.SO flange and WN flange looks similar from their appearance and some people think they can be replaced,actually they according to with the same specification like ASME B16.5,ASME B16.47,ISO 7005-1-2011,BS 4504-3.1,DIN EN 1092-1 and so on.The Weld Neck Flange vs Slip On Flange.- Coastal Flange BlogJun 01,2020·The Slip On Flange is connected to the pipe by two welds,one on the back side of the Flange and one on the inside of the Flange.The inside weld of the Flange to the pipe is recessed a minimum of the wall thickness plus 3 millimeters or 3/16 of an inch.This is to avoid damage to the gasket seating surface or face.Types of Stainless Steel Slip On Flanges - Akai Metal IndiaSince the pipe slips into the flange before welding,slip-on flanges have a low hub.The flange is welded on both the inside and outside to ensure that it is strong enough to avoid leakage.Why you Should use Stainless Steel Slip On Flanges.Some contractors prefer Slip On Flanges to Weld-neck Flanges because of the lower initial cost.
Oct 23,2002·308,2,1 Slip On Flanges.(a) A Slip-on flange shall be double-welded as shown in Fig.328,5,2B when the service is (1) subject to severe erosion,crevice corrosion,or cyclic loading; (2) Flammable,toxic,or damaging to human tissue,(3) under severe cyclic conditions,(4) at temperatures below -101 DegC (-150 degF).Welding slip on flanges - American Welding SocietyJan 10,2006·On a slip-on flange,we'll run a pass of 6010 and then go with 7018 over that.We recess back 1/2 to stay away from the raised face or mating surface of the flange and still put in a nice fillet on the ID of the pipe,you know,sometimes those slip-on's have plenty of slop in em'.By fbrieden Date 01-10-2006 13:32When do we use slip-on flange,a weld neck flange or a lap If lap joint flanges are the flanges called for by the line class then you may only use lap joint flanges.For other line classes you would normally use only weld neck flanges for all flange situations for 3 (NPS) and larger.The use of a slip-on flange could be an exception here only when there is a
Slip-on flanges must be slid into the pipe before welding.In this case it is a double weld,both inside and outside,thus providing the durability they need to avoid leaks.Their pressure resistance is rated at approximately 2/3 of that of a welding neck flange.Slip-on flanges are suitable for low-pressure applications and are easy to install and weld onto different pipes.In addition,welding helps to reduce manufacturing costs.Slip On Flange Specifications and Dimensions - Octal FlangeSlip on flange,also called SO flange.It's a kind of flange slides over the pipe with internal design is slightly larger than the pipe.Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe,the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange.
