SDML
The drill pipe slip type SD is one of the most widely applied products favoured by our customers for oil well drilling. According to gripping length, this range of product can be classified into Short type (SDS), Medium Long type (SDML) and Extra Long type (SDXL), which are used for shallow well, middle-deep well and deep well, respectively.
Designed with three pieces of slip body and standard 1:3 taper, this drill pipe holding tool can fit API standard bushing and insert bowls perfectly. Through the combination of different slip bodies and suitable inserts, the drill pipe slip can be used to grip drill pipes with outer diameter from 2-3/8" to 7". Currently, we can supply drill pipe slips of SD, DU, W and B types. The spare parts of those types except the type W are interchangeable with that of international famous brands. Through replacing the inserts of the drill pipe slip, application on pipes with different diameters can be realized (please refer to Technical Parameters).
