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.

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: How to solve frequent borehole collapse and slurry leakage in fractured formations, loose rock layers and aquifers during deep hole drilling?
A:
A: HW casing is a heavy-wall and high-rigidity drilling pipe. It effectively supports unstable complex formations, prevents borehole wall collapse, and isolates water leakage layers. It perfectly solves common drilling problems such as slurry loss and poor water return, ensuring stable borehole forming in high-risk formations.
Q:Q2: Ordinary casing is easily squeezed and deformed under high formation pressure in deep drilling. How to avoid casing deformation?
A:
A: Made of premium 4130 alloy steel with full-body quenching and tempering treatment, HW casing features ultra-high collapse resistance and compression resistance. It withstands strong formation extrusion force and structural pressure, avoiding pipe deformation and damage in deep, high-pressure drilling conditions.
Q:Q3: Traditional coupled casing causes high running resistance, borehole scraping and stuck pipe issues. How to improve drilling efficiency?
A:
A: HW casing adopts a flush joint, coupling-free design with uniform outer diameter. It greatly reduces running and pulling resistance, eliminates coupling sticking and borehole wall scraping, and ensures smooth operation in deep holes and deviated holes.
Q:Q4: Ordinary casing threads easily slip, climb or break under high torque drilling conditions.
A:
A: Equipped with standard 4 TPI high-strength threads and precise inner & outer shoulder fitting structure, HW casing provides excellent torque resistance, tensile resistance and shear resistance. It effectively prevents thread loosening, slipping and breaking under heavy-load high-torque working conditions.
Q:Q5: Repeated make-and-break causes thread galling, seizing and severe wear, shortening casing service life.
A:
A: The threads adopt professional surface heat treatment with high hardness and wear resistance. They resist galling and seizing after repeated assembly and disassembly, reducing tool loss and drilling downtime caused by thread failure.
