The collapse rating is a critical mechanical property, with many suppliers claiming ratings of ≥4000psi, a threshold necessary to withstand external formation pressures without deformation. Similarly, the burst rating, often cited as ≥1000psi, ensures the screen can handle internal pressure surges. Buyers must confirm that these ratings are based on standardized testing protocols and are applicable to the specific pipe weight and wall thickness of the ordered unit, as these factors significantly influence the screen's structural integrity under stress.

The internal flow control mechanism, often defined by the ICD diameter and orifice configuration, requires precise verification to ensure proper inflow distribution. Specifications such as an ICD diameter of 2.5 to 3.2 mm and a specific number of orifice holes per ICD are crucial for achieving the desired flow restriction characteristics. The wire size of the filtration mesh, which may be specified as 3.55.0mm, directly impacts the filtration精度 and pressure drop across the screen. Additionally, the number and size of internal rods, such as 5.0mm48PCS, contribute to the overall structural support and flow dynamics.
