The quantity, length and fittings can then be written in - e.g. “4 off x 1” bore Corroflon, AS, SS, RC, DRC-300 hose x 3.00 metres long (10ft). Both ends non-lined ANSI 150# S/S Flanges”.
OR by Part Numbers.
Any special requirements relating to the hose construction, or information required on Tags, or Certificates, or special testing of requirements, must be specified in full on the enquiry or purchase order.
PTFE Liners include, Standard (GP) or Special Purpose (SP), both available either in natural white PTFE or in black, Antistatic PTFE (AS). There are four types of braid, Grade 304 stainless steel (SS) polypropylene (PB), Hastelloy (HB), PVDF or Kynar (KYB). Rubber covering and other external protection systems are also available.
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.
