XXh in piping is a determination of the wall thickness of the pipe. XXh stands for double extra heavy (or double extra strong) under an old standard measuring system. It has the thickest pipe wall of any other. The actual thickness is dependent on the nominal pipe diameter. Present determination of wall thicknesses of pipes is called schedules. Schedule 10 pipe is the thinnest while schedule 160 is the thickest. Heavy pipe is slightly thicker than today's sch. 40 pipe, extra heavy slightly thicker than sch. 80 pipe, and double extra heavy is slightly thicker than today's sch. 160 pipe.
XXh pipe is no longer in use commercially and has been replaced with schedule 160 pipe, XXh Brass or Bronze pipe is forged or molded from bronze, rather than Iron or steel.
Some wall thicknesses of double extra strong pipes are:
1/2 inch nom. dia. = 0.294 inch thick
3/4 inch nom. dia. = 0.308 inch thick
1 inch nom. dia. = 0. 358 inch thick
1 1/4 inch nom. dia. = 0.382 inch thick
1 1/2 inch nom. dia. = 0.400 inch thick
2 inch nom. dia. = 0.436 inch thick
What else can I help you with?
What is the pressure rating of XXH pipe?
Its d schedule rating of pressure of pipe...
Does black steel pipe have the same pressure capacity as schedule 40 steel pipe?
What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.
How do you conet PVC pipe to lead pipe?
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
How do you remove a broken chrome bathroom sink drain pipe from the brass pipe in the wall?
There should be a nut around the chrome pipe holding it to the brass. Loosen the nut and pull the chrome pipe out.
Is it o.k. to use carbon steel pipe with brass valves?
There are instances when corrosion occurs at the junction of a carbon steel pipe and a brass valve. This is often the result of a pipe threading failure.
Is it OK to connect brass pipe to chromed pipe?
No! That will create intergranular corrosion
Do you need pipe dope for brass to brass?
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.
Can you contact brass to plastic pipe?
yes
Are watts brass pipe fittings recyclable?
Yes all brass object can be recycled.
Is it okay to connect copper pipe to brass to galvanized to brass and back to copper or will it cause a reaction that will corrode the pipes?
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
How do you seal cpvc pipe into brass fitting?
Pipe joint compound or Teflon tape
Can you use brass and galvanized pipe for a gas line?
No.
