The fittings shall have external lugs to provide a locking arrangement that will permit connection (or disco
17、nnection) of any two of the fittings by turning one into (or out of) the other a quarter of a turn. The fittings shall be furnished with lockwire holes. When the fittings are snapped together, at least one of the lockwire holes on each fitting shall line up to receive a lockwire or safety pin. A pre
18、formed packing shall be furnished with each fitting. 3.3.2 Type I coupling. The type I coupling halves shall conform to the configuration shown in figure 1 (see 7.6), and shall be the size specified (see 2.2). 3.3.3 Types II and III coupling halves. Type II and III coupling halves shall conform to t
19、he configurations shown in figures 2 and 3, respectively (see 7.6), and shall be the size specified with ASME-B1.20.1 NPT threads. (see 2.2) 3.3.4 Types IV and V coupling halves.
