Best Answer

It depends on the diameter of the flange, the type of pipe, the materials, the type, size and grade of bolts, type, grade and size of the flange, and the pressure and temperature of the fluid transported in the pipe.

Some pipe flanges require very little torque on their bolts while others need as much as 500 foot-pounds of torque, or more. The design and application will determine the required torque.

Why does a drain flange have holes in it?

To allow floor flange bolts to have a place to fit and to anchor the flange to the cement /wood decking


What is a counter flange and how is it different from a normal flange?

The term"counter flange" is used in Europe to refer to a mating flange to make up a flange pair. For example a "counter flange" attached to a pipe must have the same bolt circle diameter, number of bolts, and size of bolts and pressure rating at the equipment nozzle flange provided by an equipment manufacturer.


Should you glue your toilet closet flange to your pipe?

No, it is not recommended to glue the toilet closet flange to the pipe. The flange should be secured to the floor using bolts or screws, and the toilet is then secured to the flange using wax rings or sealing gaskets. Gluing the flange to the pipe can make it difficult to remove or replace the toilet in the future.


How do you replace cast iron flange?

You have to take the lead and packing out that is holding the flange in the next piece of pipe. If your flange is broke where the toilet bolts go, this is very common. There is a repair available for this. It consists of two curved pieces of metal that are about 1/3 of the circumference of the flange. They go under the flange and give you a new place to put the bolt. They are a lot easier to use than replacing the whole flange.


How do you connect a plastic toilet flange to a lead drain line in cement basement floor?

First, in order to accomplish this task, be sure the plastic flange fits the opening in question. It this is new work and anchor bolts or anchorbolt holes are not already in place, fit the flange to the lead drain line as you want it to go and by this guide, using a cement bit, drill holes in the cement(assuming the basement floor is cement). Two holes are required. After the holes are drilled, force lead inserts into the holes. These are to screw the anchoring bolts into to hold the flange stable. Choose the correct lead inserts and the side drill bit to match. Any hardware store can match these up for you. The remount the flange, through the proper holes in the flange, the ones you used as a guide for the holes, then insert the ancholr bolts and tighten down. It Holes are already in place and no lead inserts are already in the holes, simply obtain the proper inserts, bolts and Voila! do according to the above, simple yes?

What is the proper torque for the head bolts?

The torque loading for head (and many others) bolts varies with the engine concerned. It is important to check the manufacturers handbook to ensure the correct loading is applied. It is also important to tighten the bolts on the sequence indicated in the manual and by increments to the final loading. If no sequence is given then it is good practice to tighten from the centre out. For most 'standard' car engines it will be around 50 ft lb.
