Long Venturi Blasting Nozzles

   —USVC series blasting nozzles from BSTEC

We all know that the blasting nozzles have two basic bore shapes, the straight bore, and the venturi bore. A nozzle’s bore shape determines its blast pattern. The right abrasive blasting nozzle shape can greatly improve your workplace efficiency.

You can find various types of blasting nozzles in BSTEC. In this article, you will learn our most popular type: USVC series Long venturi type blasting nozzles.

Characteristics of USVC series Long Venturi Blasting Nozzles

l  Long venture-style blasting nozzles yield about a 40% increase in productivity compared to straight bore nozzles, with around 40% less abrasive consumption.

l  Long-venturi nozzles allow high production blasting at a distance of 18 to 24 inches for hard-to-clean surfaces, and 30 to 36 inches for loose paint and soft surfaces.

l  The nozzle liner can be made from boron carbide or silicon carbide. Boron carbide liner material is the most abrasive-resistant, durable nozzle liner material; silicon carbide liner material is less durable than boron carbide but economic and almost the same weight as boron carbide liner.

l  1-1/4-inch (32mm) entry ensures maximum productivity with a 1-1/4-inch (32mm) ID blast hose

l  Rugged and durable aluminum jacket with red/blue color PU cover

l  Non-binding 50mm contractor threads (2”-4 1/2 U.N.C.)

l  Nozzle bore size varies from No. 3 (3/16” or 4.8mm) to No. 8 (1/2” or 12.7mm) in 1/16-inch increments

Instructions on Operation of Long Venturi Blasting Nozzle

The operator inserts the nozzle washer into a contractor-thread nozzle holder and screws in the nozzle, turning it by hand until it seats firmly against the washer. With all related equipment correctly assembled and tested, the operator points the nozzle at the surface to be cleaned and presses the remote control handle to begin blasting. The operator holds the nozzle 18 to 36 inches from the surface and moves it smoothly at a rate that produces the desired cleanliness. Each pass should overlap slightly.

Note: The nozzle must be replaced once the orifice wears 1/16-inch beyond its original size.
