什么是制药级软管，食品级软管，卫生级软管，生物工程软管？都有哪些标准？

Product application:Widely used for transportation or delivery of low temperature food, cosmetics, chemical materials or the fluid or semi liquid fluid of pharmaceutical industry and biological engineering.(such as the suction of food or dairy products; the connection hoses used on food machinery liquor equipment; oil production equipment and medical equipment, etc.)

制药级软管广泛的应用于运输或输送低温食品、化妆品、化工和制药行业和生物工程用的液体或半液体流体。抽吸食品类乳制品；食品机械设备用连接管；酒类用连接导管；油类设备抽吸用的连接管，医药设备连接管路、导管等）

Product structure:Weave: without any fabric layers. All transparent state

Steel wire: a single layer of 304 stainless steel wire, the spacing is 5MM

产品结构：    无任何织物层。全透明状态采用单层304不锈钢丝，间距为5MM

Product characteristics:-The working temperature range: -40 to +120 degrees Celsius and it can reach 150 degrees Celsius in a short period of time-With a good bend, the inner wall is smooth and clean, easy to be washed, no water sticking, After cleaned by cleaning materials, no residue remained. The steam disinfection and sterilization can be done under high temperature and high pressure.

-No smell, tasteless, non-toxic, durable.

-Product will not produce any decomposition after high temperature of 180 degrees Celsius * 4 hours of high temperature Vulcanization with strong bearing capacity of negative and positive pressure.

-These hoses are usually highly transparent and the movement of fluid can be observed.

产品特性：工作温度范围‘-40ºC / +120ºC 在短时间内可达到  150ºC

具有极好弯曲性，内壁光滑清洁，易清洗不粘水，用清洗物清洗后不附着任何残留物，可采用高温高压蒸汽消毒和灭菌。无嗅、无味,完全无毒，耐用。产品经过高温180ºC*4小时高温硫化后，不分产生任何分解物，承正负压能力强，具体参考数据表。这些管通常是高透明的，可以看到流体通过时动向。

Quality certification:The hose has passed the certificate of limitation usage of hazardous substances (RoHS) in accordance with the EU directive 2008/95/ECC

品质认证：PU管依照欧盟指令2008/95 / ECC的限制使用某些有害物质(RoHS)认可。
