Selecting the Hose Grade There are two types of PTFE liner available, natural (GP) and anti-static (AS) and four types of braid, Grade 304 stainless steel (SS) polypropylene (PB), Hastelloy (HB), PVDF or Kynar (KYB). These are described on pages 11 and 12. Rubber covering and other external protection systems are also available, described on pages 13 and 14. A hose grade is specified by using the abbreviations given. For example, Bioflex AS,PB would describe a hose with an anti-static PTFE liner and a polypropylene braid. Step-up End Fittings The very high flow rates of Bioflex hose relative to convoluted hose make it possible to use a smaller bore size Bioflex hose assembly with 'Step-up' size end fittings, where the end fitting size is one size larger than the hose size. Thus, a lighter weight, more flexible hose can be used without compromising the flow rate! Bioflex is available with a range of 'standard' end fittings (described on pages 15-22), normally supplied hygienically PTFE lined and flared. End Fitting Materials All hose end fitting spigots are supplied made from Grade 316 SS, and all ferrules, swivelling nuts and flanges are from Grade 304 SS, or Grade 316 SS if Grade 304 is not available. Grade 316 SS and Grade 304 SS, depending upon the method of manufacture, will be to one of the following specifications: Grade British Standard American Standard German/Euro Standard 316 316 S31 AISI 316 1.4401 316 316 S11 AISI 316L 1.4404 316 316 C16 CF8M 1.4408 304 304 S15 AISI 304 1.4301 304 304 S11 AISI 304L 1.4307 304 304 C15 CF8 1.4308 Selecting the Hose Length Bioflex hose assemblies are made up to the specific lengths required. The hose length is taken as the length from the sealing face at one end of the hose to the same at the other end. The length tolerance is normally +5%-0%.
