Precision casting screw twist pipe fittings, also known as internal thread pipe fittings, thread buckle pipe fittings, internal and external wire pipe fittings, internal and external tooth fittings, mainly using casting process, precision casting model casting, external surface bright fine, thread using CNC lathe, fine, no burr, external surface whitening treatment, beautiful and beautiful, corrosion resistance.
Main material:201, 304SS, 316SS, copper, carbon steel, etc
Thread type：R，RC，G，ZG，BSPP，BSPT，PT，NPT，M
The main threads of fine casting pipe fittings are ZG, G, PT, BSPP, BSPT, R, RC. The main specifications are DN8=1/4,DN10=3/8,DN15=1/2, DN20=3/4,DN25=1,DN32=1-1/4,DN40=1-1/2, DN50=2. DN65 = 2-1/2, DN80 = 3, DN100 = 4.
Specification：
The corresponding relationship between specifications and metric system is generally: DN6=1 minute =1/8, thread length 6.5. DN8=2 minutes = 1/4, thread length 9.7. DN10=3 minutes =3/8, thread length 10.1. DN15=4 minutes = 1/2, thread length 13.2. DN20=6 minutes =3/4, thread length 14.5. DN25=8 minutes =1 ", thread length 16.8. 1-1/4 thread length 19.1, 1-1/2 "thread length 19.1. 2 "thread length 23.4. 3 "thread length 29.8.
