Thread mills produce NPTF threads

摘要

Emuge Corp. has expanded its line of thread mills and insert mills that are designed to solve problems with leaking pipe joints in the petroleum and natural gas industries. The new thread mills produce American Standard NPTF dryseal taper pipe threads. The company says its thread mills produce threads with the precision, dimension, and finish to consistently achieve leak-free joints. Three types are available: Straight-fluted thread mills produce NPTF tapered pipe thread diameters 1/16 in. to 2 in. Spiral-fluted thread mills produce NPT/API thread diameters 1/16 in. to 2 in.
