Over torquing bolts can cause deformation of the rubber expansion joint flanges, thus resulting in possible premature failure. Tighten bolts in stages by alternating around the flange. Usemended torque values above to achieve a good seal. Never tighten an expansion joint to the point that there is metal to metal contact between the expansion joint flange and the mating flange.

Bolt Torque Table to achieve a good seal. Tighten bolts until the rubber bead flangepressed 1/8. Measure the gap between the rotating metal flange and pipe flange, then tightening until this space is decreased by 1/8. Keep in mind that it requires less torque load to seal the rubber bead than a full face rubber flange.
The above table gives torque settings for plastic flanges, whether using metal or PVC backing rings. As long as your plastic pipe is aligned correctly during installation, and you are using an EPDM or FPM gasket, there is no need to tighten beyond these limits. It is very dangerous to pull a pipeline straight by a few degrees by tightening a flange into a fixed body. PVC and ABS pipe is not

Nevertheless, uncertainties often arise when choosing. This calculation tool helps you toponents and tightening torque. To do this, select the material and dimension of the pipe and
Torque values assume that Nickel Anti Sieze thread lubricant is used. If bolts are to be torqued dry, increase wrench setting by 20 . Table is for standard pipe flanges only. Consult LGT Engineering for flange bolt up procedure, target bolt stresses, and guidelines for non standard connections.
There is a Blair note on this called RUBBER LINED PIPE FLANGE BOLT TORQUING PROCEDURE. It is imperative to follow this procedure. After following this procedure, the gaskets mustpressed 25 30 not to exceed 33 . If this is not the case, the durometer and state of cure of the gasket must be verified as well as the accuracy of the torque wrench. This article is intended to be a
In general, it is not a good idea to specify bolt torque for tightening rubber gaskets on flanges. Torque can vary over a 2 to 1 ratio.
Torque is based the higher of 40 of bolt yield, T3 or 4800 psi gasket stress up to either the maximum allowable material stress or a maximum bolt yield of 60 . The above was calculated using the proposed ASME Gasket Constants ROTT Testing, Ecole Polytechnique for each material.
Does anyone have amended torque values for rubber lined Piping? The lining is neoprene on regular CS pipng.The actual rubber lining extend over the flat face gasket area so no gaskets are required.

To firm the flanges squarely together, Hand Tighten, then pre tighten all bolts in proper sequence to 10 20 foot pounds torque, but do not exceed 20 of the TARGET TORQUE. ______7. Re check any flange adapter face gap and LJF gap for uniformity. **** ______8.
The pressure class or rating for flanges is given in lbs. For example: 150lb, 150 lbs, 150#, depending on the gasket type, it is advisable to re torque after the first heat cycle. Ultimately if a flexible gasket is under too much pressure it will extrude out around the flange, and eventually exit right out of the flange space both internally and externally. In this situation, if it is an
rubber lined and glass coated cater for abrasive and corrosive conditions. Screwed and flanged ranges. Rolled thread spindle provide ease of operation and lower torque for open and close.

Getting the maximum allowable torque values from the flange manufacturer is the first step in the selection process. Elastomer Rubber Lined Flanges natural, EPDM, neoprene, etc. Elastomer or rubber linings can provide chemical and permeation resistance, but the othermon reason for this type of liner is abrasion resistance in industries like mining where slurries are prevalent.

To obtain a leak free flange connection, a proper gasket installation is needed, the bolts must be assign on the correct bolt tension, and the total bolt strength must be evenly divided over the whole flange face. With Torque Tightening the application of preload to a fastener by the turning of the fastener's nut the correct bolt tension can be realized. Correct tightening of a bolt means

30/07/2020· Based on the area of the NPS 12 ring gasket, a 2,000 psi gasket load corresponds to an individual bolt load of 14,500 pounds and a resultant bolt torque of about 210 foot pounds. Therefore, the NPS 12 flange bolts for a rubber gasket should be tightened in the range of 60 to 210 foot pounds.
