company news about Design Showcase and Characteristics of Tungsten Carbide Nozzles for Petroleum Applications in Different Global Regions

(1) Common Nozzle Types and Characteristics

North America typically uses cross groove type, external hexagonal type, and arc-shaped (plum blossom arc) nozzles. These nozzles feature high wear resistance, corrosion resistance, and high strength, enabling long-term operation in corrosive drilling fluid environments containing H₂S, CO₂, and high-salinity brine.

(1) Common Nozzle Types and Characteristics

The Middle East commonly uses internal cross groove type, plum blossom arc type, and hexagonal design nozzles. These nozzles provide extremely high hardness and wear resistance, assisting roller cone bits, PDC bits, and diamond bits in fast mud jetting. They optimize flow dynamics and reduce turbulent losses.

• Internal Cross Groove Type: Cross groove carbide spray nozzle​
• Plum Blossom Arc Type: Plum shaped tungsten carbide jet nozzle​
• Hexagonal Type: External hexagonal thread nozzle

(2) Leading Drill Bit Companies Using These Nozzles

• Schlumberger: Its subsidiary Smith Bits specializes in drill bit production.​
• Baker Hughes (BHGE / BKR): A long-standing giant in the drill bit field (formed through the integration of the original Baker Hughes).​
• Halliburton: Sperry Drilling, its division for drilling tools and services, includes drill bit operations.​
• National Oilwell Varco (NOV): ReedHycalog is its renowned drill bit brand.​
• Weatherford: Maintains its own drill bit technology line (smaller in scale than the top three giants).
• Saudi Drill Bits Company (SDC): Jointly established by Saudi industrial investment firm Dussur, Saudi Aramco, and Baker Hughes, focusing on drill bit manufacturing and related technologies in the Middle East region.

(2) Leading Drill Bit Companies Using These Nozzles

• Gazprom Burenie: A subsidiary of Gazprom, Russia’s largest integrated drilling service and equipment provider. It produces a full range of drill bits (roller cone, PDC, diamond bits) for harsh environments like the Arctic and Siberia, and complex geological conditions (hard and abrasive formations).​
• Izhburmash: Located in Izhevsk, the capital of Udmurtia, it is one of Russia’s oldest, largest, and most technically capable professional drill bit manufacturers, with roots in Soviet-era military and civilian production.​
• Uralburmash: Based in Yekaterinburg, it is another major Russian drill bit manufacturer and a key industrial base established during the Soviet era.
