Product Information

N-80, another API grade (see Figure 3), also has a minimum yield stress of 80,000 psi but is different from L-80 in that the former has a more significant maximum yield stress of 110,000 psi (shown by point “B”). The oil tubing coupling can solve the problem of fatigue fracture in the existing coupling due to stress concentration. Oil tubing end is connected to the inside wall of the coupling in a tapered thread. The coupling body end and oil tubing are connected with same thread pitch flat thread. The coupling is not easy to produce fatigue fracture, and has good connection effect. It can prevent the accident of oil well pipe string break effectively. Casing coupling The connection is the type of thread used to connect the joints of casing. API thread types are short thread (STC), long thread (LTC), buttress and extreme line. A number of proprietary premium casing threads are also available.

Casings that enclose the elastic on waistbands are prone to twisting, especially with consistent use. You can prevent this issue by topstitching the elastic:Specialized have made the GRID TRAIL casing to cater to riders who are pushing the capabilities of their trail bikes more than ever, riding more technical trails and at greater speeds. Such riding is very demanding of tires, especially when we’re all wanting to run lower pressures for maximum traction, but are still asking our tires to be bulletproof. That’s why you’ll see the 2020 Butcher, with its new tread pattern ( keep reading), Eliminator, Hillbilly and Slaughter MTB tires running TRAIL GRID casing.

A slightly different metal string, called production tubing, is often used without cement inside the final casing string of a well to contain production fluids and convey them to the surface from an underground reservoir. Finally, it all comes down to the direction in which the food and drink manufacturing market is headed – a need to maximise efficiency, save on processing and labour costs, create greater sustainability in their operations and follow the emerging market trends dictated by the end-consumer. In the world of sausages, alginate casing systems have an answer to all those points. Overlap the elastic ends with a zigzag stitch and stretch the elastic to hide the ends inside the elastic N = a function of the number of thread turns from hand-tight to power-tight position, as given in API Spec. 5B, Threading, Gauging, and Thread Inspection of Casing, Tubing, and Line Pipe Threads, [2] Was this article helpful? We just learned what is casing in sewing, which is an enclosure made by folding the fabric or sewing it separately so the elastic, ribbon, or drawstring will be within it. It’s relatively easy to do, but remember that the casing should be ¼ inch wider than what you’ll put through it.Mitchell, R.F.: “Casing Design,” in Drilling Engineering, ed. R. F.
