T bevel with protractor and dividers In use. A sliding T bevel, also known as a bevel gauge or false square [1] is an adjustable gauge for setting and transferring angles. . Different from the square, which is fixed and can only set a 90° angle, the sliding T bevel can set any angle and transfer it on anoth
Steel pipe is often joined with threaded connections; tapered threads are cut into the end of the pipe, and sealant is applied in the form of thread-sealing compound or thread seal tape (also known as PTFE or Teflon tape) and the pipe is screwed into a threaded fitting with a pipe wrench. Threaded steel pipe is widely used in buildings to ...
Street elbows are available with bend angles of 90°, 45°, and 22.5°. They can be used in many plumbing applications, including water supply, drainage, sewers, vents, central vacuum systems, compressed air and gas lines, heating and air conditioning, sump pump drains, and other locations where plumbing fittings would be used to join sections of pipe.
A structural pipe fitting, also known as a slip on pipe fitting, clamp or pipe clamp is used to build structures such as handrails, guardrails, and other types of pipe or tubular structure. They can also be used to build furniture and theatrical riggings. The fittings slip on the pipe and are usually locked down with a set screw.
It involves installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends. Sliplining has been used since the 1940s. [1] The most common material used to slipline an existing pipe is high-density polyethylene (HDPE), but fiberglass-reinforced pipe (FRP) and PVC are also ...
The slip joint includes a gasket that fits snugly on a pipe end, with a threaded nut behind the gasket, but with gasket position adjustable as needed. This pipe end fits loosely into another with a flange for the gasket to seal against, and threads for the nut to clamp the gasket to the flange.
Schematic of a slip band, relative to the measurement axes (𝑥 1, 𝑥 2, and 𝑥 3), and axes related to the slip-band (𝑥, 𝑦, and 𝑧), showing the angles that describe the relationship between these axes and the traces of the slip band (𝛼, 𝜃), and the inclination angle (𝜓) of the slip trace (𝑥) and Burgers vector (𝑏 ...
However, slippage of a slip-critical connection in columns may lead to column instability. Slippage of a slip critical joint in a roof truss could result in unintended ponding effects. The faying surfaces of slip-critical connections must be properly prepared in order to maximize friction forces between the surfaces joined.
