The pump casing we offer can meet the followings:
1. Tolerance size of the casting shall conform to ISO8026-3 DCTG 13-RMA 6(RMAG H)-GCTG 7-DS
2. Cracks, burnt, sand and slag inclusions are not allowed. On the unhandled surfaces should not be defects reducing the strength, performance and degrade casting presentation. Allowed correction of welding, in which defective cutting may be performed by the manufacturer's instruction. Locations of these defects in the casting and the butchering size under welding must be registered and entered in the casting documents. After removal of butchering defects, the surface should be grinded and monitored for completeness remove defects by dye penetration
3. Carry out UT of the castings: the end surfaces along the entire length in the area of the flange connector of the pump housing and cover (zone 1) in the area of the suction flange connector (zone2),in the area of the discharge flange connector (zone3), permitted without correcting defects of the equivalent size to 5mm not more than 3pcs.
4. The conformity checking with the chemical composition of the steels should be carried out from the each melt.
5. The steel mechanical properties: Tensile strength not less 441MPa, elongation Q not less 19%, impact strength not less 392KJ/m2, hardness HB 121-151. The mechanical properties of the steel are necessary to control for each melt. Test results apply to all the castings from this melt, heat-treated in the same mode, record by automatic devices.
