Hainan MPP pipe and PE pipe are different. Hainan nodular cast iron manhole covers are introduced to you. Mpp pipes are welded by hot melt welding. the welding joint has high strength and can be dragged by super length and high traction force. it has good toughness and excellent anti stratum settlement and seismic performance. MPP pipe overcomes the disadvantage that the mechanical properties of PE pipe decrease greatly when the temperature is above 40 ℃ and cannot be used for cable duct

The anti-corrosion measures of Hainan nodular cast iron well cover. In fact, the anti-corrosion effect of Hainan nodular cast iron well cover is very good in practical application. But if we don't use it well, the anti-corrosion products will also become non anti-corrosion, which is the most basic reason. So how do we use it to carry out some anti-corrosion treatment? Let's have a look.
