Check cone for deformation of geometry by using the cone gauge KONU. 检查预装器要使用锥度仪 KONU
(after every 50 assemblies)用锥度仪KONU定期检查预装器(每安装50个接头 检查一次) • The use of unsuitable, damaged or worn out tools can cause the failure of the tube connection.预装器不恰当使用，损坏或者磨损会导致管路连接的失

效 • Worn out tools must be replaced. 发现磨损，立即更换 • Average tool life-time is approx.5000 cycles when properly used. Maximum
lifetime can be achieved by following factors预装器平均使用寿命5000次,遵 守下列事项,至关重要:
• Pre-assembly tools must be checked regularly with ”KONU“ cone gauges (after every 50 assemblies) 用锥度仪 KONU定期检查预装器(每安装50个接头检查一次) • Keep pre-assembly tools clean and lubricate regularly 定期清 理并润滑预装器

Thin-walled tubes 薄壁管
Thin walled do not have the hoop strength;一般来说，薄壁钢 管没有足够的环向强度层 Tube collapses, shallow bite of ring;而在卡套安装时，容易造 成薄壁钢管的“坍塌”, 从而减薄卡套的咬入 Potential for tube blow out;会有潜在钢管拔脱的可能
• Recommendation: Tube deburring tool 226推荐使用226祛毛刺 工具

Cleaning (remove internal / external burrs) 清除管路中灰尘, 碎屑,毛边等
Wet Cleaning TH6-6

• Pre-assembly tools must be checked regularly with “KONU“ cone gauges (after every 50 assemblies)
Check contour检查锥面: The back of the cone gauge must be flush with or above the cone end. 锥度仪后端面
须少许高出锥口起始面
