A ceramic elbow connects at two ends, but a purchase description may show a detailed requirement for only one. The other end should not acquire its definition by assumption. For a Sanxin inquiry, identify End A and End B using the accepted component and route references. The actual construction may confirm matching requirements or specify differences; the order needs to make that relationship explicit before the component is treated as interchangeable with its intended position.

Use the controlled drawing to define the two ends and relate them to the equipment arrangement. Keep the viewing convention clear so the names do not reverse when a loose elbow is turned in the workshop. An informal upstream label can help only when its relationship to the accepted flow and component reference is established.
Identify the relevant mating item at each end. A component tag and a connection description serve different purposes. The order should let the receiving and installation teams recognize which accepted detail belongs at each physical interface without guessing from transport orientation or the first end shown in a photograph.
Where one drawing detail is intended to govern both ends, state its applicability clearly. Where the ends differ, retain the separate references and supplied boundaries. Do not copy a convenient detail into the undefined end merely because both appear circular or share a nominal pipe description.
The responsible equipment reviewers should establish applicable connection, sealing and complete-system requirements. This article provides no flange selection, tightening or adapter procedure. A ceramic material description cannot resolve an unprovided mating detail, and a favorable fit at one end does not accept the other connection or its internal lining termination.
Receiving evidence should identify which end and feature were examined. A single connection image should not be described as proof of both ends unless the actual record establishes that coverage. Preserve any inaccessible or unresolved feature rather than assume symmetry from the overall elbow appearance.
For a hypothetical example, a spare inquiry includes an accepted detail for End A while End B points to an earlier mating arrangement. The team resolves both references before closing the offer. This is configuration review, not a Sanxin connection discrepancy or a claim that the ends must differ. The actual accepted component requirements determine the relationship.
For a Sanxin request, provide both mating references, the component drawing and any fixed installation constraints. Ask the offer to show the applicable construction and deviations at each end. Clarify site-supplied connections or other work explicitly instead of letting a short complete-elbow heading hide an unfinished boundary.
At installation, retain the final End A and End B relationship with the accepted route and component identity. If one adjoining item changes later, review the affected end rather than silently extend the earlier acceptance. Clear references support a practical replacement without inventing an adapter, declaring universal interchangeability or treating one correctly documented joint as complete evidence for every connection of the ceramic-lined assembly.
Confirm its accepted applicability. Identify End A and End B and their mating references explicitly, retaining any differences. One end drawing or fit result does not independently establish the other end, its lining termination or the complete installed connection requirements.
