Product Description

Cooper castingpipemould for ductile iron pipes

Production range: DN75MM-DN1200MM

The material of pipe molds is 21CrMo10 and 30CrMo to DIN17350, and size DN50-DN1200. they are used for producing ducitle iron pipes basd on centrifugal machines.

The main technical specification of the pipe moulds are as per follows:

6. Test method and standard

Test spots: half spot of wall thickness,two portraits of such spot.

Tensile test: GB/T288-2002 standard.

Hardness test: GB/T231 standard.

7. The standard of ultrasonic test

The forging of the mould will be ultrasonically tested as per JB/T1581-1996 or equivalent standard, details as follows:

a. Without bursts, crack, shrinking hole and other defects.

b. The defect with size within 2mm can be ignored.

c. There should not have compact district.

d. Individual defect with diameter of 2~4mm is permitted, and the distance of the neighboring defects should be more than the 10 times of the bigger one’s. For 100cm2’ s area, the quantities of the defects with diameter of 2~4mm should not exceed 3.

The above-mentioned parameters are for reference only,we can produce various kinds of pipe mold as per customers’ requirements.
