Boron Carbide Nozzle – The Ultimate Tool For Abrasive Blasting
A nozzle is at the core of any blasting process, as its shape, size and material will have an immense influence over results.
Long Venturi-style nozzles produce a wider blast pattern and increase abrasive velocity by up to 100% at any given pressure, increasing productivity by approximately 40% and cutting consumption by approximately the same margin.
High Hardness
Selecting the proper nozzle size is key to the blasting process. While larger nozzles may provide faster work but consume more media and power, smaller ones save on media but may slow down blasting time.
Material selection for the nozzle liners is an important consideration. Tungsten carbide is typically the least costly but tends to crack under rough handling; while boron carbide offers greater hardness and impact resistance – making it more suitable for aggressive abrasives such as aluminum oxide, garnet and silicon carbide. Furthermore, Roctec(r) composite carbide offers even longer service life than standard tungsten carbide nozzles when exposed to these aggressive abrasives.
Special angle nozzles, industrial gun inserts and etching nozzles can help you access tight spaces such as behind flanges or pipes. Always wear a NIOSH-certified dust mask when working with abrasive blasting media; for added protection against rebounded dust particles. A full body blast suit may also provide further defense from possible rebound effects.
Long Life
Boron carbide blast nozzles offer longer durability compared to more common materials like aluminum oxide. Their fracture toughness and strength make them the superior choice for demanding blasting applications with continual blasting operations.
Industrial-grade cleaning nozzles feature larger bores to allow for increased air use and acceleration of the abrasive, providing for more effective cleaning operations. These are perfect for both industrial and commercial settings.
Venturi nozzles feature narrow input and wide output channels to maximize movement for the abrasive. This design can increase removal rates up to 15%.
Size of Nozzle Dependent upon Machine Model for Blasting Media and Compressed Air The size of a nozzle depends upon your machine model’s capacity for blasting media and compressed air, with different sizes offering differing cleaning rates on various surfaces. Banana Nozzles or Angle Nozzles should also be kept on hand to clean tight areas like bride lattice, behind flanges, or inside pipes – saving time by not having to switch nozzles frequently.
Low Wear
Boron carbide nozzles offer superior durability and wear resistance, making it the go-to choice for professional abrasive blasting applications that demand high performance and long life spans.
Abrasive blast nozzle shapes determine its blast pattern. Nozzles typically come equipped with either a straight bore or restricted Venturi-style bores; straight bore nozzles create tight blast patterns suitable for spot blasting or blast cabinet work, while long Venturi-style nozzles offer wider patterns and can increase abrasive velocity by as much as 100% for any given pressure level.
Nozzles come in various sizes, and their size affects how much media and how quickly your project can be completed. Larger nozzles may be more efficient but cost more in terms of both media and power consumption; smaller nozzles may be preferable as saving media may be more important than efficiency in certain cases.
Easy Maintenance
Blast nozzles come in all sorts of sizes and shapes. Selecting the ideal one depends on both the abrasive you are using and its blast pressure; larger nozzles can accommodate more media faster but require more power and air while smaller nozzles save on media usage while working more efficiently but may take more time to be effective.
Bore shapes play an integral part in creating the blast pattern produced by each nozzle, with straight bore nozzles producing tight blast patterns ideal for spot blasting or cabinet work, while venturi-style nozzles produce wider, more diffused patterns ideal for larger jobs like weld seam shaping, carpentry and stone carving.
Angel nozzles, industrial gun inserts and pencil blast nozzles can all help increase efficiency while decreasing maintenance costs. Nozzle liners and window protectors may also decrease maintenance requirements when working with high wear materials such as cutting abrasives.
