GVF Impianti's wear resistant bends and terminal boxes are made in order to solve common wear problems in pneumatic conveying pipe lines.

Increase durability, maintenance costs reduction are some of the common goals that this solutions allow.


Wear resistant segmented bend type CM


GVF Impianti wear-resistant segmented bend CM series is composed by three interchangeable sectors with rotary split flange and a gasket interposed. 

The rotary split flanges permit to make path and direction diversions, removing the need of placing and welding the tubes in the construction site.

In this type of bends the transported product is not subjected to particular losses of load, due to the bend’s large average range. All bend’s components are molten in high quality NiHard cast iron that, in order to guarantee high mechanical properties, is carbonitrurated.

Especially appointed for dense and dilute phase conveying systems

Gaskets in high quality vulcanized rubber

Suitable for abrasive materials

Split-flanges PN 10

Made in cast iron NiHard carbonitriding

Wear resistant squared bend type CSQ Sand over Sand


GVF Impianti’s wear-resistant squared bend CSQ series is produced in carbonitrided NiHard cast iron, in order to give it an high hardness and wear resistance. The bend’s special design permits the material to deposit and create a protective shield on the bend’s walls. This is the reason why it is generally called SAND-OVER-SAND bend. 

CSQ bend is produced in the version with two ways (CSQ2) or with three ways (CSQ3). Both versions are supplied with rotary split flange, produced in cast iron NiHard too, that permits to turn the bend around its own axis of rotation as you prefer, guaranteeing the highest flexibility during the execution of the pipes and the layout of the ways. Outfitted with eyebolt for uplift, it is supplied with gaskets made in vulcanized rubber.

Especially appointed for dense and dilute phase conveying systems

Split flanges PN 10

Suitable for abrasive materials (silica sand, sand blasting residues)

Gaskets in high quality vulcanized rubber

Made in cast iron NiHard carbonitrided

Terminal boxes PAAS used as a transport pipeline termination


The terminal box is used as a transport pipeline termination. 

It is installed at the end of a series of DAS diverter valves or on systems with only one receiving point. Its dimensions are lower than a long radius bend.
The terminal box allows tangential entry of material into the receiving hopper; 
the material is deflected through 90° by a wear-resistant deflector plate which is easily accessible for inspection or replacement.
