pipe joints?

Answer 1

Depends upon the pipe and the method of joining.

Copper pipe which has a soldered joint is considered to have a joint weaker than the pipe. Solder is a lead-tin or silver-tin allow which is brittle.

Iron pipe with screw on joints, usually has Teflon tape at the joint and if screwed on tightly is very leak-proof and mechanically sound.

Plastic pipe usually uses a solvent to melt the pipe and joint fitting. The solvent evaporates leaving a joint which has almost identical properties as the plastic used in the pipe.

Glass "pipe" used in laboratories can use ground-glass fittings or Teflon or even melted glass on glass. This is the most variable of any joint.

Different types of pipe joints?
1.welded joint-butt weld,socket weld.
2.welded flange joints-as per ASTM/BS/IS/JIS/DIN STANDARD using a different types of gaskets(CAF/spiral wound-different moc).w.r.to pressure rating
3.expansion joints-especially in hot services like steam,reboilers....
4.GLUED joint-pvc pipe joints - uses a solvent to fill the gap and make leakproof joints as in case of water services.
5. cemented joints-gutter line,road crosser,irrigation aplication.
6. most corrosive services uses pph/p.p./hdpe pipe lines which can be jointed by hot plate use and plastic welding.
7.screwed joints: like union joints,coupling joints,threaded flange joints -can be sealed using ptfe tape rolls and using gasket shellac.
8.Brazed joints-for refrigeration piping in liquid line for the moc like copper,brass.......
Question asked is not giving full details- so i understood this.

Answer 3

i decided to become a pipefitter when i found out that dope comes in five gallon buckets and joints were 20 feet long!!

Answer 4

T- joint, Elbow, Reducer, Coupling, Nipple & (welding, bracing, etc).

Answer 5

yeah, probably the best way to go under your particular circumstances. just remember to keep your cylinder nodes clean when you're working under pressure.

Great question!!
