Oil & Gas Machining


from close relationships with key OEM suppliers of tooling, workholding and software. “Our VIP tooling partners, for example, have developed new boring bars with different types of materials and designs that keep harmonics from developing and damaging surface finishes,” said Scott. “In the past prior to having this technology, it wasn’t uncommon for opera- tors and programmers to strap lead weights to boring bars for dampening to minimize chatter during the boring and/or threading process of internal diameters.”


Threading Critical to Integrity of Heavy Pipe Strings For the all-important threading of drill pipe and casing, Mazak has developed its PT20 Premium Threading System, which rotates the tool around the part instead of having to rotate pipe that is 30 or 40' (9 or 12-m) long with diameters up to 20" (508 mm) and weights over 18,000 lb (8165 kg). “There are two basic thread types in the oil patch: Premium and API threaded connections. The Premium threads are patented


AME engineered the AMLOK hydraulic rod locks for the AZ- 10 subsea tree from 4140 steel with electroless nickel plat- ing and a specially formulated two-part epoxy to create a completely sealed unit.
