Jiangsu, ChinaKey features
Flush Joint Coupling free :Male and female threads on both ends enable direct connection with inner and outer shoulders closely fitted.
The contact area is twice that of conventional coupled casings, delivering high torque and collapse resistance and preventing thread loosening under heavy torque.
Parallel Heavy-wall Body
Uniform wall thickness, excellent concentricity and straightness. Fully compatible with PQ wireline coring systems and allows smooth passage of PQ inner tube assemblies.
High-strength Threads
With surface heat treatment, the threads feature superior pull and shear resistance under impact and vibration, effectively reducing thread galling, wear and seizing.
Full-body Heat Treatment
The entire pipe undergoes quenching and tempering to enhance strength and toughness, extending service life in deep-hole and hard rock drilling conditions.
Large bore diameter: 139.7mm outer diameter, excellent passability. Compatible with PQ coring and high-flow flushing fluid.
High strength & reliability: Thick wall and direct connection design deliver superior collapse, torsion and tensile resistance, ensuring safe operation in deep holes and complex formations.
Wireline coring compatible: Fully matched with PQ system. Coring without tripping out improves working efficiency and reduces labor intensity.
Wear resistance & anti-galling thread: Threads are quenched for enhanced performance, preventing thread seizing during repeated make-and-break and lowering failure rates.

AI-Powered supplier vetting
SummaryCge Group Wuxi Drilling Tools Co., Ltd. is a China-based, state-owned supplier established in 1980 with 162 employees, offering drill pipes, drill bits, and drilling accessories. It reports broad customization capability, documented inspection and service procedures, and machinery including CNC, hot-press, grinding, milling, sawing, drilling, and automatic CNC production equipment. The supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications and conducted regular fire drills during the past year. Its R&D function introduced new products during the past year and supports customization, but it does not provide ODM services or an SDK. Overseas service infrastructure is limited: it reports no overseas warehouses, showrooms, agents, branches, offline trade-show participation, or countries served. Financial information is represented only by years, without performance values, so financial credibility cannot be fully assessed. No customer cases are provided.
Supplier typeThe supplier is identified as Cge Group Wuxi Drilling Tools Co., Ltd., a state-owned company in Wuxi, Jiangsu, China, established in 1980, with 162 employees. Its stated product scope is drill pipe, drill bits, and drilling accessories, and it is not identified as part of a larger company group.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These explicitly indicate coverage of quality, occupational health and safety, and environmental management systems.
R&D capabilityThe supplier reports new products during the past year and supports customization from samples, designs, full customization, minor customization, and flexible customization. It does not provide an SDK or ODM services, so the evidence supports product development activity but not a complete innovation-service offering.
Production capacityThe listed equipment includes CNC lathes, hot-press, grinding, milling, sawing, pier drilling, and an automatic CNC production line. The supplier also reports uniformly followed finished-product inspection instructions and lead times within 15 working days in both peak and off-seasons, supporting established production and inspection capability.
Customization capabilityBoth the design-services and R&D records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
Product Q&A
Q:Q1: When drilling deep holes and complex formations, the borehole wall is prone to collapse and slurry leakage. Can PW casing solve these problems?
A:
A: Yes. PW casing is a heavy-wall high-strength pipe with excellent rigidity. It effectively supports unconsolidated layers, fractured zones and aquifers to prevent borehole collapse. Its good sealing performance also isolates water-leaking formations and resolves slurry loss, ensuring stable borehole conditions.
Q:Q2: For large-diameter wireline coring, conventional casings have insufficient inner diameter and block drill tools. How does PW casing improve this?
A:
A: PW casing is fully compatible with the complete PQ wireline coring system. It features standard and ample inner diameter, allowing smooth movement of inner tube assemblies and overshots. It eliminates tool jamming and guarantees normal wireline coring operations.
Q:Q3: Casing with couplings has larger outer diameter, leading to high running resistance and sticking risks. What are the advantages of PW casing?
A:
A: PW casing adopts flush joint design without couplings. The uniform outer diameter greatly reduces running and pulling resistance. It avoids coupling sticking and scraping against the borehole wall, especially ideal for deep and deviated holes.
Q:Q4: Under high torque in deep-hole drilling, threads of ordinary casings are easy to slip, seize or break. Does PW casing perform better?
A:
A: Absolutely. Equipped with dedicated 4 TPI high-strength threads and internal/external shoulder positioning, it delivers outstanding torque, tension and shear resistance. Thread hardening treatment prevents galling and seizing during repeated make-and-break, avoiding thread failure under heavy loads.
Q:Q5: Poor concentricity of regular casings causes borehole deviation and severe wear. Can PW casing fix this issue?
A:
A: Yes. Manufactured with high precision, the pipe has superior straightness and concentricity. It provides reliable guidance during drilling, reduces tool wear and borehole deviation, and extends service life of both drill tools and casing.
