Dimensional inspection
OD, bore, thickness, facing, and bolt circle are checked against the named standard or drawing.
Manufacturing and inspection
Process and inspection the RFQ can name
Forging through packing, with dimensional inspection, PMI, UT, MT, hardness, and material traceability available on the order.
Manufacturing process
The sequence below is the usual industrial path. Inspection scope follows the purchase order or drawing.
-
01
Forging
Carbon, stainless, low-temperature, and alloy grades are forged to the ordered type and size.
-
02
Heat treatment
Heat treatment follows the material grade and the specification on the RFQ.
-
03
Machining
Hubs, bores, facing, and overall dimensions are machined to the named standard or drawing.
-
04
Drilling and facing
Bolt circles, RF / FF / RTJ facing, and special drilling follow the class or buyer drawing.
-
05
Inspection
Dimensional inspection, PMI, UT, MT, hardness, and material traceability are available with the order.
-
06
Marking and packing
Steel stamping, export packing, and shipping documents are prepared for the destination market.
Inspection scope
Dimensional inspection, PMI, UT, MT, hardness testing, and material traceability.
PMI
Positive material identification is available when the grade must be confirmed before shipment.
Ultrasonic testing
UT is quoted when the specification or drawing requires volumetric inspection.
Magnetic particle testing
MT is available on carbon and alloy steel surfaces as listed on the RFQ.
Hardness testing
Hardness follows the material grade and the inspection list on the purchase order.
Material traceability
Heat numbers and mill certificates travel with the lot. Extra reports follow the RFQ.
Third-party inspection
Buyer-nominated inspectors can attend when the purchase order names the agency and hold points. Do not treat this page as a certificate list.
