Which is good Cangzhou Fastener Quality

Which Cangzhou good quality fastener scaffolding fastener | construction fasteners | Bowl Fasteners | steel fasteners: Working height: 5000 (m), the entire tower bearing: 950000 (kg), material: cast iron, scaffolding Category: scaffolding buckle member: Scaffolding fastener, supply scaffolding and accessories manufacturer Cangzhou GB construction fastener factory Contact: Li Xue-Gang (Manager) Tel: 0317-6215198 Mobile: 15831737699 Fax: 0317-6215198 scaffold fastener Price: scaffold fastener manufacturer: Cangzhou GB construction fastener plant [standard] using a fastener, model specifications 1, right angle fasteners KZФ48A (GB15831-2006) --- according to GB 15831 specifications for fasteners, the country numbered bits 20062, rotating fastener KUФ48A (GB15831-2006) --- according to GB 15831 specifications for fasteners, the country numbered bits 20063, docking fastener KDФ48A (GB15831-2006) --- according to GB 15831 specifications for fasteners, the country numbered bits 2006 II. fasteners use Application: various types of construction fasteners used in construction projects, an outer diameter of Ф48mm steel scaffolding, derrick, template support such as the use of steel fulcrum, the intersection of fastening, for water, chemicals, metallurgy, mining , railways and other infrastructure projects apply. Third, use a right angle fasteners: for vertical fastening two steel cross-linking, the longitudinal and transverse rods of steel scaffolding pipe coupling fastened right angle fastener, it should be from the bolt torque (tightening degree) 40N · m , make sure the cross pipe in the external load is not generated by the decline in the phenomenon. 2. Rotate the fastener: for two pipe cross-linking fastening any angle. That is coupled torsion scaffolding scissors and high-rise buildings used by steel scaffolding and at right angles away from the double-sided column of the same fastener. 3, docking fastener: docking for two pipe coupling, the main transverse vertical pipe horizontal pipe, bracing lengthening. Fourth, the main technical parameters of a fastener, construction fasteners using GB944-88 "malleable iron" requirement, the mechanical properties of not less than malleable cast iron grades KTH330-8 requirements, 2, product testing according GB2828-8 "batches inspection Sampling procedures and sample forms "provides secondary health check sampling program. 3, construction fasteners moving parts can be flexible rotation, rotation of the two rotary surface fastener clearance less than 1mm. 4, when the fastener clamp pipe, the minimum opening distance 5mm.
