The quality of today's cutting teeth greatly improves the erosion and impact resistance of the drill bit. Engineers also optimized the interface between tungsten carbide substrates and synthetic diamonds to improve the toughness of the cutting teeth. Innovations in the layered diamond process have also been used to improve the abrasion and thermal stability of the product. PDC products have also achieved significant breakthroughs in tooth design techniques and gear teeth. Today, PDC products can be used in harder, more abrasive and lithologic formations. Currently, PDC bits are increasingly crowding the market for roller cone bits in many drilling applications.
The anti-slip texture of the cap and body is easy to screw cap.
The tube cap has an O-ring built-in gasket to prevent liquid leakage.
The cryo tube is suitable for ultra-low temperature refrigerators, and the tolerance temperature is -86~121 °C, and it can be repeatedly frozen and thawed.
In the gaseous state of liquid nitrogen, it can withstand low temperature to -167 ℃.
According to different requirements, there are ordinary grade and PCR grade. PCR grade products are free of DNase, RNase, endotoxin and foreign DNA. Sterilized by gamma irradiation, sterile.
PDC product market is getting wider and wider
The hardness of diamond is 10 times that of steel, twice that of tungsten carbide, the wear resistance is 10 times that of cemented carbide, and the compressive strength of diamond is 20 times that of granite. The use of diamonds has become an irreversible trend in oilfield drilling operations.
