01How does Kaiyue control the raw material quality of Pamalo ng rotary jet drill?
All steel materials are purchased from qualified large steel mills, and each batch is inspected after arrival before it is released for production.




Ang mga high-strength jet grouting drill rod ay partikular na idinisenyo para sa mga high-pressure jet grouting at mga proyektong pampalakas ng pundasyon. Ginawa mula sa mataas na kalidad na seamless alloy steel at precision machining, ang mga ito ay nagtataglay ng mahusay na high-pressure sealing at torsional strength, na tinitiyak ang mahusay at matatag na high-pressure grout injection sa mga kumplikadong kondisyong heolohikal.
Sabihin sa amin ang iyong mga kondisyon sa pagpapatakbo, target na dami, at iskedyul ng paghahatid, at itutugma namin sa iyo ang naaangkop na modelo, teknikal na datos, at panukalang presyo.
All steel materials are purchased from qualified large steel mills, and each batch is inspected after arrival before it is released for production.
Kaiyue drill pipe bodies use R780 steel, selected for strength and durability in demanding drilling conditions.
The upset ends increase the friction-welding contact area, helping improve joint strength and reduce the risk of connection fracture.
All friction-welded areas are tempered after welding to reduce internal stress and improve long-term structural stability.
The coupling is made from 42CrMo steel and processed through overall heat treatment and deep nitriding.
The coupling core hardness is about HRC 34, while the nitrided surface hardness can reach about HRC 57 for a balance of toughness and wear resistance.
Quality control runs from rough machining through welding, heat treatment, nitriding, threading, and final inspection before shipment.
Stable raw materials, strengthened pipe ends, treated welds, and inspected couplings help lower the risk of equipment failure during drilling operations.
