Umehluko phakathi kwe-EN39 ne-EN74 Staffling Scafting Pipe

Bobabili i-EN39 ne-EN74 bayizindinganiso zokukhiqizwa kweAmapayipi ensimbi e-ScaffoldingEmazweni aseYurophu. Ipayipi lensimbi scaffolding lisetshenziswa ikakhulukazi njenge-bracket ye-coupler-Type Insimbi Pipe Pipe Scaffold, eyakhiwa ngokugoqa umucu oshubile ngenqubo.

I-En39 Standard iyizinga laseYurophu. I-Standard idinga ukuthi ishubhu lensimbi elisezingeni eliphansi lenziwe ngensimbi ephansi yekhabhoni noma insimbi ye-alloy. Ubukhulu beshubhu lensimbi ngu-3.2 mm futhi wamukele ukuphambuka kwe-PLUS noma ku-10%.

Ngaleso sikhathi, i-EN74 Standard futhi iyindinganiso yaseYurophu. Izinto zepayipi zensimbi ezidingwa yileveli ziyefana ne-En39 ejwayelekile. Ubukhulu bepayipi lensimbi buyadingeka ukuba ube ngu-4.0 mm futhi wamukele ukuphambuka kwe-PLUS noma ku-10%. Ingaphezulu liphathwa nge-galvanizing eshisayo.
