Inspection of product and finished product quality and teaching 3 Material preparation
3.1 Steel pipe
Acceptance of steel pipe, verification of quality, no-exposure inspection, etc. shall be carried out in accordance with the relevant provisions of "Industrial Pipeline Engineering Acceptance Specification". 3.1.2
The linear deviation of steel pipe shall not be greater than 3mm per meter, and the total length shall not be greater than 5inm
If it exceeds the specified value, it shall be used after passing the inspection. 3.1.3
The roundness deviation of high-pressure steel pipe shall not be greater than 21m3.2 Cement
The cement grade shall not be lower than 425.
For the lining of pipes for conveying sewage, slag silicate cement, volcanic ash silicate cement or fly ash silicate cement shall be used. For the lining of pipes for conveying water, ordinary silicate cement, silicate cement or slag silicate cement shall be used. 3.2.3 Slag silicate cement, volcanic ash silicate cement and fly ash silicate cement shall comply with the provisions of "Slag silicate cement, volcanic charcoal silicate cement and fly ash silicate cement": silicate cement and ordinary silicate cement shall comply with the provisions of "Portland cement, ordinary silicate cement". 3.2.4 During transportation and storage of cement, attention should be paid to moisture-proof and waterproof. 3.2.5 Cement should have a factory quality certificate and re-inspection report. 3.3 Fly ash
