旋转式钻探和振动用橡胶软管和软管组件.规范ISO 6807-2003

ISO 6807:2003 specifies the requirements for textile- and steel-reinforced rubber hoses and hose assemblies for use with water-based and/or oil-based muds, up to a maximum temperature of 82 °C, which are pumped at high pressure in large volumes in rotary drilling service and which, when tested in accordance with ISO 2977, have a minimum aniline point of 66 °C. This International Standard applies to hoses which are suitable for use at ambient temperatures between -20 °C and +52 °C, unless changed by a supplementary requirement on request of the purchaser, and are resistant to ageing and tropical conditions. This International Standard does not apply to hoses which are intended for use with gases.
