Import Api Spec 7k Rotary Drill Collar Slips Type Wt — Buy in wholesale FOB from Supplier in China

The Api Spec 7k Rotary Drill Collar Slips Type WT from Dongying Lake Petroleum Technology Co., Ltd. are forged carbon steel handling tools designed to grip and suspend drill collars during well drilling operations. The WT series covers four model ranges: WT 4 1/2-6 (114.3-152.4 mm O.D.), WT 5 1/2-7 (139.7-177.8 mm O.D.), WT 6 3/4-8 1/4 (171.4-209.6 mm O.D.), and WT 8-9 1/2 (203.2-241.3 mm O.D.). Each model carries a maximum load rating of 40 short tons and uses either API or No. 3 insert bowls. Unit weights range from 39 kg to 49 kg depending on size class.

These slips employ a multi-segment body construction that permits size adaptation through insert quantity adjustment rather than dedicated slip sets for each collar dimension. The forging process yields grain flow oriented to withstand radial gripping forces and axial loads transmitted during drill string make-up and break-out. Carbon steel selection balances strength against cost in a consumable handling tool category where periodic replacement is expected. All slips undergo post-machining inspection, which for this product class typically covers dimensional verification, hardness testing, and visual examination for forging defects or surface cracks.

Buyers include drilling contractors, rig operators, and oilfield equipment rental firms servicing land and offshore wells. The API Spec 7K compliance indicates suitability for drilling and well servicing equipment applications where interchangeability with other API-compliant rotary rig components is required.
