1: Chemshun introduction :
Process ceramic alumina pipe of various dimensions for different fields of wearable conditions. Alumina pipelining is characterized with excellent wear resistant property and long service life; smooth surface, low friction coefficient; resistant to most kinds of acid, alkali and salt; low thermal expansion coefficient and thermal conductivity, operating temperature can be up to 1500 centi-degree max . Chemshun ceramics can engineer and manufacture a totally new pipe system or individual components that will solve customer's piping problem . Alumina pipe linings are pre-engineered with proper side bevel to achieve full face to face contact and maximum interlock .customized and standard-end connections are available .
2:Chemshun ceramic tube pipe advantages :High hardness Superior abrasion Corrosion and chemical resistance Light weight Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost.Good fluidity : Smooth surface ensure the free flow of material without blocking
