Acceptance points and common risks
- Cross-crossedMultiple intersections thicken and form a detection blind area.
- The pipeline sinks at different stagesThe remaining residual rigidity of the connections will tear the edges.
- Sealing aluminum substitutesThe sealing valve is only auxiliary and cannot replace the mechanical fixed and continuous valve.

Project judgments and procurement conclusions
The angle of incidence and the conductivity are the most susceptible places of the insulation system to fail due to stress concentration, and the connection between the aluminum and the isomer. The base angle should be made of a circular arc or reverse angle; the main membrane should pass as smoothly as possible, so that it cannot be flattened using pre-fabricated plates of the same material. The conductivity of the conductivity is preferred by the use of sealing PE tubes with the conductivity, metal or concrete interfaces, and by design by mechanical pressing bars, sealing bars and water-stop construction.

Steps to landing
- Reviewing the node mapThe number of pipes in the pipeline is the number of pipes in the pipeline.
- Treatment of the baselineThe main feature of the system is the sharp edges of the pipe, the walls of the pipe, and the surrounding walls.
- Making templatesThe first sample is made of thin film, and the film is then cut and filled with the same film.
- Testing for re-evaluationAfter the squeeze pump is completed, vacuum or spark detection and photo numbering are performed.

Key parameters and quick judgement tables
| The nodes | Recommended practices | Prohibited practices |
|---|---|---|
| The inner corner | Round-angle base layer + butterfly filling | The small, multilayered pieces are stacked on top of each other. |
| The outside | Prefabricated round/shaped plates | The hard-paste corner of the main membrane |
| PE through the pipe | The same material as the tube + the squeeze tube | Just seal the door. |
| Interfaces with different materials | Pressure bars + seals + stiffness | The first is to use the hydrophobic acid to make the metal. |
