INTRODUCTION
Corroline hose was designed and developed to provide customers with a universal chemical hose product which combined all the requirements they had requested for chemical plant applications, particularly the need for improved flexibility.
Corroline hose not only supersedes but also improves upon the wide variety of alternative Chemical Hose products currently available.
CONSTRUCTION
Corroline is built around a patented PTFE hose liner design, which is smooth bore inside but convoluted outside to generate excellent flexibility combined with 'hoop strength'.
A stainless helical wire and stainless steel wire braid reinforcement add to the kink resistance, crush resistance and the resistance of the hose to both pressure and vacuum.
This reinforced PTFE construction is therefore strong enough to withstand full vacuum and kinking without the need for either internal convolutions or the need to bond the liner to an outer cover, making it an ideal hose liner design, and a significant improvement upon standard products currently available.
The PTFE liner is then further reinforced with an outer braid, either a Stainless Steel wire braid (SS Grade) or a Polypropylene braid (PB Grade) to provide two braided hose grades.
The most popular grade (RC Grade) includes an outer cover of abrasion resistant, black antistatic EPDM rubber which is extruded on to a SS braided liner, with a super-smooth surface finish to aid external cleaning. A yellow, 'CORROLINE' stripe is printed on to the cover. Other texts and coloured stripes are also available to special order.

Tygon® 2075 ultra chemical tubing
Tygon® Ultra Chemical Resistant Tubing offers an unequaled combination of chemical resistance, clarity and flexibility. Tygon® 2075 is virtually unaffected by acids, bases, ketones, salts and alcohols, fitting the requirements of many applications from battery acid filling to hazardous material handling. It's entirely plasticizer-free, eliminating fluid contamination and the premature embrittlement and cracking common with many flexible tubings. Its exceptionally smooth inner surface inhibits particulate buildup and reduces the potential for
contamination.

Chemical hoses from ContiTech cover the whole spectrum of standard hoses for the chemical and pharmaceutical industries in accordance with EN 12115.
Special processes - some of them patented - provide for safe transport of various media. This includes both hoses with elastomer inner linings as well as plastic-clad ones.
New innovations include hoses with light-colored plastic lining. With their integrated conductor helix, the hoses comply with all requirements for a Ω hose as contained in EN 12115 while at the same time guaranteeing product purity.
Process-patented petrol pump hoses from ContiTech do not bleed colors and are conductive, extremely lightweight, flexible, buckle-proof and weather-resistant. They can be rolled up, have an extremely smooth, bright-colored finish and guaranteed calibratable volume increase. The compounds used allow for good resistance to swelling and diffusion. The "hose-in-hose" principle provides for automatic gas recirculation - and thus contributes actively to protecting the environment and human health.
