Heat Resistance Pb Pipe Pressure Resistance Pb Pipe

PB Pipe

The Diameter (Outer Diameter) Of PB Tube Has Four Specifications: 16mm, 20mm, 25mm and 32mm. PB Tube Can Be Mechanically Clamped Connection, Plug Connection, Hot Melt Connection. At Present, There Are Many Types Of Accessories, Which Can Basically Meet The Needs Of Engineering Applications. The Bearing Capacity Of PB Pipe Is Related To The Wall Thickness Of The Pipe And The Temperature Of The Medium Through Which It Passes - Water, And The Temperature Of The Medium Needs To Be Defined.
