Solvent cement is applied when the pipe surface is tacky. Use only industrial grade CPVC solvent cement.

Proper welding to ensure life expectancy When welding piping systems, it’s imperative that the joints and fittings maintain the same life expectancy, pressure rating and safety factors throughout. For extremely harsh environmental applications, CPVC resin-based cement, a special grade solvent, is used to make sure that the joints maintain the same life expectancy, pressure rating and safety factors as the piping system itself. Tese solvents meet the American Society for Testing and Materials (ASTM) standards to ensure that the joining surfaces are softened and made semifluid and that the gaps are filled sufficiently. Te highly durable and corrosion resistant
CPVC resin-based cement piping systems result in meeting critical demands for harsh industrial mining applications. Tis combination provides an excellent balance of properties that improve reliability and user confidence. It also reduces capital and life-cycle costs, avoiding costly downtime and most importantly, allowing mining processing plants to remain operational and more productive. l

After cement application, the pipe should immediately be inserted into the fitting socket and rotated 1/8 to 1/4 turn until the fitting-stop is reached.

Cone crusher offers reduced emissions M
etso has introduced a new cone crusher, the HP5. Automatic settings, specialised
maintenance tools, reduced emissions and energy-efficient motors are just a few of the improvements built into this new cone crusher. The Nordberg HP5 follows the HP3, HP4 and HP6 as the fourth model in an all-new range of cone crushers. With 5% larger feed size versus the HP400 and higher capacity than the
HP500 in tertiary applications, the HP5 is pioneering in its class. In addition, a higher cavity density improves interparticle crushing action for end products with more consistent gradation and superior shape. An advanced fastening system for the
mantle and bowl liner eliminates the need for backing material, and makes liner changes safer and faster. Thicker liners result in more material to wear. The HP5 cone crusher is also easy
to disassemble, and all components are accessible from the top or side. The bowl and head are easily and safely removed with no interference. A new motor support allows the belts
to be stretched hydraulically, and lifting points have been redesigned to easily and safely lift the HP5. Platform guards help to ensure
operator safety and protection. l For more information, visit
