A manhole cover and a large industrial-equipment casting need their own drawing and material requirements. This OEM enquiry includes ductile-iron covers and separate grey-iron components, with sand casting, deburring and machining scope. Dimensions are customized, and sandblasting is the named surface treatment.
Define the cover and frame interface
For a manhole-cover request, show the cover geometry and the interface to its frame. Identify the required iron grade and the load-class acceptance established by the project. Those requirements should be provided with the drawing rather than inferred from the manhole-cover description.
- Identify a cover or separate industrial casting.
- Provide the controlled drawing and selected iron grade.
- Mark interfaces requiring machining and acceptance limits.
- Describe service conditions and required inspection.
Specify the large industrial part separately
Provide the full envelope and mating geometry for a grey-iron equipment component. Identify the material, required quantity and delivered condition for that design. The large-part description does not define a numerical size or load capacity, so include the project dimensions and operating requirements.
Agree X-ray inspection and surface acceptance
Quality-control scope identifies an X-ray flaw detector. Define the inspection coverage, method and acceptance criteria required for the ordered part. Specify the sandblasted result and any deburring or machining instructions relevant to its interfaces.
Identify the order's document requirements
Wooden-case packing is stated for supply. ISO9001:2015 is the qualification reference; identify the applicable documentation and supplier scope. Keep these purchasing requirements alongside the component-specific drawing, material and inspection acceptance.
