Dished End Closures for Industrial Fabrication
These stainless steel heads have a curved circular body and an open rim for fitting to a mating pipe or shell. The product photographs show both the concave interior and convex exterior, together with visible machining marks around the rim. Select the required profile from a dimensioned drawing rather than from the photograph alone.
The supplier reference describes the product as an elliptical head in 310S stainless steel. For quotation, define the exact contour, material specification and joining requirements. A standard 2:1 ellipsoidal shape, particular forming process or pressure rating is not established by these images.
Product Specifications and Ordering Details
| Item | Details to specify |
|---|---|
| Product type | Circular dished head or weld-on end cap for an industrial end closure. |
| Material reference | 310S stainless steel, as identified in the supplied listing. Confirm the applicable material standard, grade and required material records. |
| Diameter and fit | Specify inside or outside diameter, mating pipe or shell dimensions, and fit-up tolerances. |
| Head profile | Provide the contour, overall depth, straight rim length and any required radii or profile standard. |
| Wall thickness | State the required finished thickness and minimum permitted thickness after forming, where applicable. |
| Joining edge | Define trimming, bevel, root face and joint details on the drawing. Visible rim marks do not establish a specified weld preparation. |
| Surface condition | Specify internal and external finish, cleaning requirements and any further treatment for review. |
| Inspection scope | Identify dimensional checks, material traceability and any special examination or documentation required. |
Selection for the Intended Service
For elevated-temperature enquiries, provide the operating and design temperatures, medium, pressure, thermal cycling and surrounding atmosphere. Material selection and suitability must be reviewed against those conditions; no universal maximum service temperature or resistance to deformation is claimed for the pictured parts.
For pressure-retaining use, include the applicable design code and approved component drawing. The head geometry, finished thickness, material and weld joint must be considered as part of the complete assembly. Any code documentation or special testing should be agreed before manufacture.
Fit-Up and Inspection
Check which diameter controls the connection before placing an order. Include the mating component drawing where possible, and mark critical tolerances for roundness, rim alignment and depth. If replacing an existing closure, provide measured dimensions in addition to photographs.
Define the required checks and records with the enquiry. These may include material identification, profile and thickness measurements, edge condition and visual surface inspection. Specific test methods and document availability are confirmed with the quotation. See our quality control information.
Frequently Asked Questions
Are these heads supplied to a standard elliptical ratio?
The reference identifies them as elliptical heads, but does not confirm a contour ratio. Send the required profile drawing or standard designation for review.
Can the cap be selected from pipe diameter alone?
No. Confirm whether the dimension is an inside or outside diameter, then specify thickness, depth, rim length, fit-up tolerances and joining details.
What should accompany a high-temperature enquiry?
Include the specified alloy and material standard, temperature range, medium, pressure and duty cycle, together with the drawing and inspection requirements.
Request an End Cap Quote
Send the drawing revision, material specification, diameter, finished thickness, head depth, rim and weld-preparation details, quantity and destination. Include service conditions and any required inspection documents so the manufacturing and supply scope can be reviewed.
