Why are bolt holes for a flange never placed on the vertical?
I would say because there has to be a standard method of installing flanges that everyone needs to follow. For the simple reason when installing or replacing items such as valves with welded or otherwise fixed flanges, if there was no standard the replacement valve would be 1/8 of a turn or 45 degrees off center if the piping flange bolt holes were on the verticle and the valve flange bolt holes were not. This would be in the case of 4 or 8 bolt flanges.Also in the case of non flanged valves where long bolts pass thru both flanges and squeeze the valve to make the seal a vertically placed bolt hole would interfere with the valve operator or handle preventing the valve from being mounted straight up, down or horizontally.
Will a two bolt toilet fit on a four bolt flang?
no such thing as a 4 bolt flange only 2 bolt. you have a toliet with 4 bolts....the front 2 bolts just screw into the floor.....yes....just put in a regular 2 bolt toilet and ignore the other two holes in the floor.
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.
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.
What is the difference in blank and blind flanges?
Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction. Piping is easier to drill or weld at the construction stage. Once it was in use, drilling or welding will need prolong cleaning especially when the fluid transferred is combustible. For the mean of future extension, either the blind or valve would be used to seal the end.
What is the different with normal flange and flange with jack screw?
Jack Screw is a sistem for dissasembling. The diference is that the flange has threathed holes where a bolt is installed.
What is a flange spreader?
A flange spreader is a device that uses a ratchet, leverage and fulcrum points to spread a bolt together connection. Usually welded pipe to flange, then a seal or gasket, and then another flange, and then welded or threaded pipe carries on. A flange spreader is used to spread the flanges apart to change a gasket or put in a spec blind to blank either side of the connection.
On a 1992 Toyota Paseo what is the gasket called that connects the header to the exhaust system I think its a flange gasket but I'm not sure?
A flange is the part of the pipe that you can bolt on a blow off valve, O2 Sensor, or other parts like that. The name that you are looking for it the Down Pipe Gasket.
What is the reason for two holing a flange?
'Two-holing' a flange means letting the two top holes evenly straddle the centreline of the pipe flange is on. The main reason for doing this is to allow proper alignment of pipework and valves as the bolt holes on valves are configured the same way as described above - two top holes straddling the centreline.
Flange and bolt chart?
The flange and bolt chart is used to give us the diameters and their bolt circles.
What tool should be used to square a flange on a piece of pipe?
Square a flange? Lol there is many hundereds of types of flanges so I don't know what flange you are talking about. If its a toilet flange and you want the toilet bolt holes equal to the wall (if its PVC or abs) just use a big pair of pliers or pipe wrench to turn it soon after you glue your flange.
How you find the pcd of flange?
PCD (Pitch Circle Diameter) is the diameter of a circle that goes through each of the bolt holes. You can find it by measuring distance from centre of one bolt hole to the centre of opposite end bolt hole...
How do you change a thermostat on a 3.4l v6 engine in a lumina?
Answer: With moderate difficulty. Typical of automotive engineers, they designed a 3/4 inch tube to block the removal of the upper radiator hose connection to the thermostat. Instead of using a simple bolt and spacer, they have a one piece bolt and stud holding the upper radiator hose connection and a brace for the 3/4 inch tube. The tube can only be properly removed if the exhaust manifold is removed, as the exhaust manifold was installed over the attachment point of the tube. Not real bright on the engineer's part. The easy way to replace the thermostat is to remove the nut holding the 3/4" tube from the flange stud. Next remove the bolt/stud holding the bottom of the thermostat flange. You may have to grind a cheap 13mm open end wrench thinner to fit the tight space. I used a cheap stubby 13mm open end ground thin. In the process of removing that bolt/stud, the small attachment bracket for the 3/4" tube will be bent. No problem...just bend it straight later. Remove the other bolt holding the flange covering the thermostat. Clean the old rubber gasket from the counter bored thermostat seat. The thermostat comes with a rubber gasket, and also a paper gasket for spacing. If you don't use the paper gasket, the flange will be bent when you tighten down on the bolts because the rubber gasket is thick. Instead of reusing the original lower bolt/stud combination, I used an 8mm-1.25 X 45mm bolt, nut, a flat washers, and a spring type split lock washer . Position the thermostat with the rubber and paper gasket, the upper radiator piping flange over the thermostat, and install the upper bolt finger tight. Straighten the previously bent attachment flange on the 3/4" tube. Put the lock washer and the flat washers onto the bolt. Now holding the 8mm nut between the thermostat flange and the flange for the 3/4" tube, screw the 8mm bolt through the tubing flange and the nut you're holding and into the flange for the thermostat. It may take two wrenches: One to hold the nut, and the other to turn the bolt. You will simply have to tighten the bold in such a manner that the nut and the bolt tighten down simutaneously to where the thermostat flange and the 3/4" tubing flange are tightened snug. It is more important that the nut holding the thermostat flange is tight than the bolt holding the 3/4" tubing flange. The 3/4" tubing only has to be secure in that it won't have any looseness. Note: Do not use a bolt any longer than the 45mm length. If you do, you'll probably crack the thermostat mount or punch through and hit coolant. This explanation sounds difficult to understand, but once you get into it, it will all make sense. You can use two or three flat washers to make sure that you don't go too deep with the bolt.

What does a head gasket look like?
picture rectangular shaped gasket, if 3 cylinders on each head each gasket has 3 circles representing cylinders and thin gasket maybe half inch wide between each circle then bolt holes for head bolts too ------------------------------------ ------------------------------------
Is there a gasket between the master brake cylinder and the booster on a 1990 integra?
There is a gasket between the master cylinder and the booster of a 1990 Acura Integra. It is shaped like the side of the master cylinder with two bolt holes.
