Product Description
Cement mortar lining:
Cement mortar lining of SLR ductile iron pipes is applied through centrifugal application method: When pipes are rotating on the lining machine, certain amount of cement mortar is poured into the pipes. Through high-speed revolution with acceleration about 30G under the centrifugal force, such cement mortar will fully cling to the internal surface of pipe, forming a dense and smooth lining with uniform thickness, which can provide good mechanical properties after curing for certain amount of time. Thickness of cement mortar lining shall comply with specifications as below:
Features of SLR cement mortar lining:
1) Self-healing with the proceeding hydration reaction of cement:
&©|160;the cement mortar lining will shrink gradually. Therefore, it is inevitable to form radial displacement and small cracks. This is a unique feature of cement mortar, which is allowable by the standard. Thus, no unfavorable influence on the mechanical stability of the lining will be brought by such cracks and radial displacement, as well as other cracks caused during manufacturing or transportation. When the pipe with cement mortar lining contact water, these cracks and radial displacement will be closed and healed along with expansion of the linings and continuous hydration of cement; therefore, the anticorrosion effect won¡¯t be influenced.
2) Good mechanical property£º
* Expansion coefficient:
The linear thermal expansion coefficient of cement mortar lining is 12 x 10-6/℃ , which is almost equal to that of ductile iron (11 x 10-6/℃ ). Therefore, it can reduce the risk of crack generation due to difference of thermal expansion coefficients.&©|160;
Good adherence and anti-vacuum performance.
Good resistance to longitud |
