A custom requirement may involve a particular interface, non-standard dimensions, special tolerances or an unusual material. The controlled drawing and specification establish what is required.
The customer-approved drawing defines the geometry and interfaces. FERROBEND supplies against the specified material, dimensions, quantity and acceptance requirements, subject to confirmation of manufacturing feasibility and availability.
02 / DRAWING-CONTROLLED FEATURES
What makes the component drawing-based?
01
Interface geometry
The drawing defines how the fitting meets the adjoining pipe or assembly. A family name alone may not express the interface.
02
Dimensions & tolerances
Controlled dimensions identify the intended geometry; tolerances define the permitted variation of specified features.
03
Material & acceptance
Referenced specifications identify the material and acceptance requirements associated with the drawn component.
03 / PRODUCT KNOWLEDGE
Understand what a controlled drawing defines.
Standard description versus drawing-controlled detail
A family name explains a fitting’s general function. A controlled drawing can define a particular interface, geometry or tolerance that the family name does not express. The drawing and referenced specifications work together to describe that component.
It is a feature that controls how the fitting meets another component or assembly. Its geometry and tolerance affect fit, so it needs a clear drawing reference.
Why is the drawing revision part of the description?
A revision identifies the issue of the drawing that defines the current component. Different issues may contain different geometry, materials or acceptance details.
04 / SELECTION CONSIDERATIONS
What matters in the application.
01
Critical features
Identify the dimensions and interfaces that control fit or function.
02
Document control
Use the current drawing number, revision and units. Flag inconsistent references.
03
Acceptance scope
State material, quantities, inspection and documentation requirements at the start.
05 / UNDERSTAND THE SPECIFICATION
