30CrMo Forged Pipe Mould
1.making ductile iron pipes DN50-DN1200
2. material:21CrMo10/35CrMo to DIN17350
3. for longtime use
4. pipe mold
Production range: DN75MM-DN1200MM
The material of pipe molds is 21CrMo10 and30CrMo to DIN17350, and size DN50-DN1200.they are used for producing ducitleiron pipes basd on centrifugal machines.
The main technical specification of the pipemoulds are as per follows:
21CrMo10 and 35CrMo to DIN17350
2. Chemical Components
electric arc furnace + refining furnace(vacuum arc degassing)
4. Technical parameters of machining
5. Mechanical properties(according to DIN17350, DIN 21CrMo10)
225 — 265HB
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.
