The examination of pipes' walls is a central area in the NDT industry due to the fact that even a small change in the pipe's wall thickness may have grave repercussions on the pipe's ability to withstand pressures and meet preset standards. Two techniques are generally used to conduct wall...
Place the thread-cutting die into the threader ratchet handle. The smooth edge of the die should face outward. Step 3 Slip the threader die over the end of the pipe to the point where it stops. The die is now engaged. Step 4 Oil the ratchet before beginning to cut pipe threads. Ste...
How to measure the shock resistance of anti-corrosion pipeline coating? According to the oil and gas industry standard SY/T 0315-97, the impact performance of anti-corrosion pipeline coating is measured. The specific operation method is introduced below.
Measure the diameter of the pipe. For example, assume the pipe has a diameter of four feet. Step 2 Determine how accurate your measurement needs to be. If you need a general estimate, you can use 3.14 as pi. If you need more accurate measurements, you should carry pi out to more deci...

Hold the fitting against the pipe, and slide the compression ring up against the fitting. Slide the nut over the ring and thread it onto the fitting until it is hand-tight. Be careful not to cross-thread the nut. Fit one wrench onto the body of the fitting and hold it so that the ...
Measure and cut the black pipe to the needed lengths. Clean the pipes with denatured alcohol. 5. Assemble the Pipe Base: Thread the pipes into the fittings, following your design plan. Paint the assembled base with black spray paint and apply a coat of satin clear lacquer for protection. ...
Thread the nuts on the shutoff valve stems. They should be flush with the front of the stems. Measure the distance between the outside edge of the iBox’s plaster shield and bolt plate. Then add 7/16” to this measurement and cut the retainer plate screws to size. The total ...
How did you weigh this piece. You mentioned a weighbridge. Typically these are made for weighing a vehicle and its load, perhaps 40 tonnes. Even a small one for 10 tonnes has an accuracy of +/- several kg (say 2 kg in 10,000, or 0.02%). So to measure 2 kg is almost impossible...
