The SUNTECHMACH pipe threading dies are replacement chasers for pipe threading machines, made in 9Cr2, SS and HSS steel. Square dies are produced for China-made pipe threading machines in 1", 2", 3", 4" and 6" sizes, while flat dies are available for REX, ASADA and RIDGID die heads. Both NPT and BSPT thread forms are offered, so a die set can be matched to the thread standard and pipe size of the job.
| THE PROBLEM | HOW WE SOLVED IT |
|---|---|
| Dies wear out quickly on hard or welded pipe | SS and HSS options; HSS lasts 500+ pcs on steel |
| Need square dies for a China-made threader | Square dies for China pipe threaders 1"-6" |
| Need flat dies for REX / ASADA / RIDGID | Flat dies for REX/ASADA/RIDGID die heads |
| Wrong thread form causes leaks | NPT and BSPT both available |
| Replacing dies too often | Use threading oil to extend life (SS >200 pcs with oil) |

| Common faults | Reasons | Solutions |
|---|---|---|
| Thread torn / rough | Wrong die size or worn dies; no oil | Use correct size; replace dies; apply threading oil |
| Dies chip or crack | Too fast feed; hard pipe; threading over welding seam | Reduce feed; use HSS dies; avoid the seam |
| Dies wear out too fast | No lubrication; wrong material for the job | Use oil (SS >200 pcs with oil); choose HSS for steel |
| Thread form wrong (NPT vs BSPT) | Wrong die thread form installed | Fit the correct NPT or BSPT die set |
| Dies do not fit the die head | Square vs flat die mixed up; wrong machine brand | Use square dies for China threaders, flat dies for REX/ASADA/RIDGID |
