The formula for cut of 4 pieces of pipe and 90% is the same as the formula for cut of any number of pieces and percentage.
The formula for cut is used to determine the length of pipe needed for a specific angle or joint.
The formula is: (pipe diameter x percentage) x 0.01745 x number of pieces
For example, for 4 pieces of 2-inch diameter pipe and 90%, the formula would be: (2 x 0.9) x 0.01745 x 4 = 0.251 inches
The take off valve for a 90% elbow is a type of valve used to control the flow of fluid or gas in a pipe system connected to the elbow.
The take off valve is typically installed at the branch or outlet of the 90% elbow.
It allows for the diversion or regulation of the flow in the branch pipe connected to the elbow.
Common types of take off valves include ball valves, gate valves, and globe valves.
The choice of valve depen...
To calculate the true length of a pipe, use the Pythagorean theorem and the formula for the circumference of a circle.
Measure the diameter of the pipe
Calculate the circumference of the pipe using the formula: C = π * d
Measure the angle of the pipe bend
Use the Pythagorean theorem to calculate the true length: L = √(C^2 + (2πrθ)^2)
The formula used in fabrication of a tee is the pipe intersecting formula.
The formula is used to determine the length of the branch pipe and the angle of intersection.
The formula is L1 = L2 x tan(A/2), where L1 is the length of the branch pipe, L2 is the run of the tee, and A is the angle of intersection.
The formula is important in ensuring that the tee is fabricated correctly and fits properly in the piping system.
Preparing a pipe for welding involves several steps to ensure a clean and secure joint.
Inspect the pipe for any defects or damage
Clean the pipe surface using a wire brush or grinder to remove any dirt, rust, or scale
Bevel the pipe ends to create a V-shaped groove for better weld penetration
Align and fit the pipes together, ensuring proper gap and alignment
Tack weld the pipes in place to hold them together during the we...
An elbow 90% is used to change the direction of a pipe by 90 degrees.
It is commonly used in plumbing and pipe fitting installations.
It helps to navigate around obstacles or to connect pipes at different angles.
Examples include connecting pipes in a water supply system or HVAC system.
Elbow 90% can be made of various materials such as PVC, copper, or stainless steel.
The basic ways of joining a pipe include welding, soldering, brazing, and using mechanical fittings.
Welding involves melting the edges of the pipes and fusing them together.
Soldering uses a filler material with a lower melting point than the pipes to join them.
Brazing is similar to soldering but uses a higher temperature filler material.
Mechanical fittings include couplings, unions, and flanges that connect pipes witho...

Pointers are variables that store memory addresses of other variables in programming languages.
Pointers allow direct access and manipulation of memory locations.
They are commonly used in programming languages like C and C++.
Pointers can be used to pass variables by reference, allowing modifications to the original value.
They can also be used to dynamically allocate memory.
Example: int* ptr; // declares a pointer to an
