Detailed specs for Medium pipe-inspection-case Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL2305 series. MOQ 30. 12h quote, 30-day delivery.
If you are sourcing Medium pipe-inspection-case Wholesale from a Chinese factory, you have probably seen marketing sheets with vague dimensions and a single IP rating. We do the opposite. Every dimension here is measured at the QC station, every rating is third-party tested.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP | Multimeter / Caliper |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+AS | Surveying Total Station |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+AS | Theodolite / Level |
The most common model for "Medium pipe-inspection-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Medium pipe-inspection-case Wholesale uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Our Medium pipe-inspection-case Wholesale buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
Ordering Medium pipe-inspection-case Wholesale is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (30 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
Our spec sheets include the manufacturing tolerance, not just the nominal value. That is what real engineers ask for.
