Import Api Handing Tools Multi-Segments Casing Slips — Buy in Bulk from Supplier in China

The Api Handing Tools Multi-Segments Casing Slips from Dongying Lake Petroleum Technology Co., Ltd are drill floor handling tools designed for gripping and suspending casing strings during oil and gas drilling and completion operations. Manufactured in Dongying, Shandong Province, China, these slips conform to API Spec 7K for drilling and well servicing equipment. The UC-3 type features a 3-inch per foot diameter taper across slip segments, with the exception of the 8-5/8 inch size which uses a different taper specification. Each segment receives equal force distribution during load application, which maintains casing ovality and reduces the risk of casing deformation under axial load. The slips are intended for use in conjunction with spiders and insert bowls of matching taper, forming an complete gripping assembly.

The multi-segment construction uses hardened alloy steel segments, a standard material choice for casing slips requiring wear resistance and structural integrity under cyclic loading. Segment hardness, surface treatment, and weld or bolt attachment method to the slip body are typical variables that affect service life and should be confirmed with the supplier. The equal-force segment design is particularly significant for heavy-wall casing in intermediate and production strings, where point-load concentration from conventional slip designs can induce collapse or fatigue cracking. The 3-inch per foot taper is an industry-standard geometry that ensures self-tightening grip as axial load increases, with wedging action converting downward pipe weight into radial gripping force. Heat treatment to achieve through-hardness or case-hardness profiles is standard practice for this product category, though the exact specification must be requested from Dongying Lake Petroleum Technology Co., Ltd.

Primary buyers are drilling contractors, oilfield service companies, and rig operators running casing in land and offshore environments. The slips are consumable wear items in active drilling programmes, with replacement driven by segment wear, taper degradation, or size changes between casing programmes. Import considerations include verifying that the supplier's API Spec 7K licence is current and covers the specific slip type and size range. China-origin oilfield equipment often offers significant cost advantage against North American or European manufacturers, but buyers should evaluate metallurgical certification, heat treatment records, and dimensional inspection reporting. Dongying Lake Petroleum Technology Co., Ltd holds imported supplier status with harbor trust tier, though no response metrics are recorded on this listing.

Dongying Lake Petroleum Technology Co., Ltd is based at Huanghe Road, Dongying 257000, in Shandong Province, China. The company operates as an imported supplier with harbor trust tier on this platform, indicating a registered profile without verified transaction history or response performance data. The supplier's product focus is petroleum drilling equipment, specifically handling tools for casing operations. No information is provided about facility size, production capacity, years in operation, or international client base.

The listing contains no disclosure of ISO certification, API licence number, quality management system, or export experience. The response rate is recorded at zero percent with zero average response hours, suggesting either a new listing or inactive profile monitoring. Buyers should conduct direct due diligence on manufacturing capability, inspection equipment, and API quality programme compliance. Request factory audit access or third-party inspection report before committing to volume orders, as the harbor trust tier alone does not substitute for supplier capability verification.
