♦ Steel plates are cut using a fully computerized plasma cutting machine with a cutting accuracy of ±0.1mm, preventing plate deformation.
♦ The end caps are formed using a spin-forming process, resulting in a seamless, one-piece molding process with uniform stress distribution.
♦ A combined robotic automated welding and manual repair welding approach is employed.
♦Longitudinal and circumferential welds are welded symmetrically by two people simultaneously, maintaining a consistent welding speed and heat input to control welding deformation.

♦ Welds undergo 100% non-destructive testing, ensuring the absence of defects such as slag inclusions, porosity, cracks, and undercut. Weld strength is no less than that of the base material.
♦ After sandblasting, the entire tank body is coated with an anti-corrosion coating.
♦The thickness of both the inner and outer coatings meets standards (outer coating ≥80μm, inner coating ≥100μm), verified by salt spray testing.
1. Equipped with an SK water-circulating vacuum pump, achieving a vacuum level ≥-0.09MPa, enabling rapid extraction of high-concentration sludge and viscous waste liquids. The vacuum level decreases by no more than 10% within 30 minutes, meeting the needs of high-level waste liquid extraction.

2. The piping system utilizes high-strength, corrosion-resistant materials with an inner wall smoothness Ra≤0.8μm, reducing fluid resistance.
3. Quick-connect fittings achieve an IP67 sealing rating, with a leakage rate of <0.1% at the connection point. It is also equipped with an anti-backflow device and an emergency shut-off system to prevent sewage backflow and secondary pollution.

♦ Appearance Inspection: Check tank flatness, coating integrity, and weld quality; no wrinkles, paint peeling, or incomplete welds are allowed.

♦ Performance Testing: Vacuum system test (vacuum degree ≥ -0.09MPa, pressure holding for 20 minutes with no significant drop), hydraulic system test (smooth lifting without jamming, no leakage), unloading test (smooth unloading at 45°, no leakage).

♦ Sealing Test: Tank body pressure stabilized at 80kPa for 5 minutes with no leakage; suction and discharge system pressure held at 15kPa absolute pressure for 20 minutes, leakage rate <0.1%.
