Page view
According to different material, DIE could be sorted to alloy and HSS, and alloy also has two kinds---9Cr2 and 9CrSi. Normally alloy DIE is used to thread on common steel pipe and galvanized steel pipe, and HSS DIE is used to thread on stainless steel pipe.
According to different threads, DIE could be sorted to BSPT (British Standard Pipe Thread), NPT (American Pipe Thread), Metric etc., we choose different DIES according to different standard and different usage of pipes.
In addition, DIE of quick-open Die Head and self-open Die Head are different, for our machine, thickness of DIE of quick-open Die Head is 10mm, and thickness of DIE of self-open Die Head is 20mm.
