HDPE pipe fusion. Heat fusion (sometimes called heat welding, butt welding or simply fusion) is a welding process used to join two different pieces of a thermoplastic. This process involves heating both pieces simultaneously and pressing them together. The two pieces then cool together and form a permanent bond.
In short, oxy-fuel equipment is quite versatile, not only because it is preferred for some sorts of iron or steel welding but also because it lends itself to brazing, braze-welding, metal heating (for annealing or tempering, bending or forming), rust, or scale removal, the loosening of corroded nuts and bolts, and is a ubiquitous means of ...
Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [ 2 ]
No craft station is complete without a stash of pipe cleaners and with good reason: These bendy beauts are budget-friendly and can be used in a variety of ways by a range of ages. Pipe cleaners ...
The rate of heating when PWHT is performed is typically based on the component's thickness and is specified by the governing codes. [1] [6] If the rate of heating is not performed properly, either by heating too quickly or unevenly, temperature gradients within the component can become detrimental to the component. As a result, stress cracks ...
The secondary heat exchanger removes most of the heat energy from the exhaust gas, actually condensing water vapour and other chemicals (which form a mild acid) as it operates. The vent pipes, also known as the exhaust system, are often installed using PVC pipe instead of metal venting pipe to prevent corrosion, but this will vary based on ...
Oct. 25—Although the Permian Basin is known worldwide for oil and gas, students in Ector County ISD didn't have a career pathway for the industry until last year. Tried as a pilot for one ...
Because of the technological trend to reduce alkali content from the majority of refractories, the amount of combined water present in the moment of heat-up was reduced in the last years. On the other hand, recent developments which led to increases in mechanical strength, thermal shock resistance, erosion resistance, etc., also led to a ...
