Tubes ? PP, SS & PVDF

Since 1980, Kijeka Engineers manufacture, design and distribute material handling equipments, barrel pumps, casters, wheels, ladders, drum handling equipments worldwide. The company offers a wide range of tubes made of polypropylene (PP), stainless steel (SS) and polyvinylidene fluoride (PVDF) materials. PP is light weight and high in chemical resistance, and tubes made of this material are suitable for service from -20?C to 90?C (-5?F to 195?F). PP is unaffected by alkalis, salts, organic solvents and most acids, particularly hydrochloric and phosphoric acid. It is unsuitable on strong acids, chlorinated hydrocarbons, aromatic compounds and high concentrations of free chlorine. PP is very inert thus popular for high purity applications such as deionised water, etc. SS 316 is a high quality metal typically used in application involving solvent based flammable liquids. In addition SS 316 is used in the pharmaceuticals, food and beverage industries. PVDF is superior to other thermoplastics in chemical resistance and abrasion resistance. The working temperature range of PVDF is -40?C to 80?C (-40?F to 175?F). PVDF has excellent chemical resistance against halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, organic solvent sand oils. PVDF is not resistant to hot bases. It is also non-toxic and imparts no odours or tastes into the fluid.
