Because in single stub method stub position has to be adjustible which create error......this is notin the case of double stub position method.........
Checkers pay stub
It requires stub should be placed in a definite point on line, it requires two adjustments both the location and the direction of the stub
The stub attached to your paycheck that you tear off before you cash it.
On the right side of the check stub.
For branching of one size lesser of run pipe, Stub On is preferred. For other branching less than one size of run pipe stub in is preferred. The Design is based on ANSI B 31.3
wath is the perimeter of a square with 9-cm sides?
There are many PDMS piping modeling commands. Some of these include: Q axes at ph= to check the head of the branch of the pipe, Q axes at pt= to check the tail of the branch of the pipe, Q Hstu= to show the branch head tube attribute, and Q Lstu= to show the branch tail tube attribute.

What the difference between process piping and power piping?
MSS-SP-97 is a standard developed by the Manufacturers Standardization Society of the Valve and Fittings Industry. It covers integrally reinforced forged branch outlet fittings, commonly known as olets, for use in high-pressure piping systems. These fittings are used to create branch connections from a main pipeline, enhancing efficiency and reducing stress in the piping system.

pipe = one piping = a system of piping arrangements
Bar Tee has got the branch opening closed with flat Bars so as not to allow the PIG to pass through the branch pipe portion than to the mainline. In case of Flow Tee the purpose is the same (i.e. not to allow PIG passage), here the flowing liquid get accumulated in the circumference of the annular space and while pig moves thru' flow tee, maximum fluid is passed on to the branch piping.
