Biopharmaceutical hose, pharmaceutical hose, pharmaceutical-grade silicone hose improper use can easily cause safety hazards, medical equipment production and delivery of often used biopharmaceutical hose, food-grade hose in the domestic use of national standards and does not have a specification for the use. The following is to explain ah choose sanitary pharmaceutical hose should be noted:
1. environment – the use of location, ambient temperature, humidity, whether exposed to reagents or ozone environment – may be in contact with the end of the hose substances;
2. positive pressure – negative pressure – working pressure and working negative pressure – potential overload pressure (including hammering)
3. type of connector, size, thread type – outside diameter, inside diameter – length adjustment – type of strap, size – type of external fastening rope (connector is quick release chuck, thread, flange connector or other forms)
4. In special cases, also consider whether the pharmaceutical silicone hose, medical silicone hose, food silicone hose, sanitary silicone hose, pharmaceutical hose needs to be conductive;
5. transmission medium medium form: liquid, gas or solid. Solid media: granular, concentration, transmission performance, type, speed, flow. Use frequency – substance type, name, concentration, working temperature. 6.
6. mechanical limits – minimum working bending radius – pulling, twisting, bending, oscillation, extrusion withstand limits – whether it will be impacted, wear, corrosion – working position: placed on the ground, hanging, submerged
7. the special case user according to the standard selection of biopharmaceutical hose, pharmaceutical hose, pharmaceutical-grade silicone hose, sanitary silicone hose, regardless of whether the field has existed industry standards, must check the special logo, mandatory norms, standards and specifications;
Most of the medical, food industry is used in line with the European and American standards of safety biopharmaceutical hose, pharmaceutical hose, pharmaceutical-grade silicone hose, sanitary silicone hose, pharmaceutical silicone hose, polyester silicone braided, high-purity platinum vulcanized silicone hose, and ray braided platinum vulcanized steel wire hose and other multi-purpose sanitary hose commonly used in medical, sanitary equipment, food processing, medical equipment processing and conveying, cosmetics Production of sanitary hoses for conveying liquids, solids, etc.
