The oil measurement hole is installed on the top of the oil tank and is used for measuring the height and temperature of the oil in the tank and for sampling. We offer environmentally friendly, rotary, threaded hole, and foot pedal types. The application scenarios include:
- Petrochemical industry: crude oil storage tanks, gasoline storage tanks, diesel storage tanks, methanol/ethanol storage tanks, etc., which require pressure balancing and prevention of flammable and explosive gas leakage;
- Grain, oil, and food industry: edible oil storage tanks, alcohol storage tanks, syrup storage tanks, etc., which require prevention of medium contamination and evaporation, and also meet food-grade hygiene requirements;
- Chemical industry: acid and alkali solution storage tanks, solvent storage tanks (such as acetone, toluene), etc., which require corrosion resistance and pressure balancing to avoid tank corrosion and leakage;
- Municipal/energy industry: LNG storage tanks (low-temperature scenarios, requiring special material breathing structures), chemical storage tanks in sewage treatment plants, etc., to ensure safe and stable storage processes.
A reliable gauge hatch is an essential component for industrial facilities. It provides secure access to storage tanks for fluid level measurement, temperature gauging, and sampling. As a leading direct manufacturer, NIPO delivers robust tank access solutions. We tailor these products for maximum industrial safety and operational efficiency. Our hatches are engineered to withstand demanding environments. They ensure quick, safe, and compliant access for maintenance personnel.
We categorize our gauge hatch models based on specific structural designs and operational benefits. This ensures every facility can find the exact access solution required for their storage tanks.
Hinged cover designs are engineered for quick, one-handed operation. This allows operators to inspect tank contents efficiently without cumbersome removal processes. These units feature non-sparking materials and secure sealing mechanisms. They prevent vapor loss and maintain standard tank access safety. For specialized hands-free operation, we also offer variations like the foot pedal type oil gauging hole. This provides added convenience and safety during routine sampling procedures.
The rotary type gauge hatch utilizes a unique rotating mechanism. It is highly suitable for specific petrochemical applications where space restricts traditional hinged access. This design ensures a tight, reliable seal while allowing smooth rotational opening. It minimizes wear on the sealing gasket over time, providing a durable solution for high-frequency use.
Security is a top priority for sensitive storage facilities. Our lockable gauge hatches are designed to prevent unauthorized access and tampering. Beyond standard security features, NIPO possesses advanced manufacturing capabilities. We can produce non-standard access designs based on specific client requirements. This ensures a perfect fit for any specialized tank configuration or unique environmental challenge.
Engineers and procurement managers require precise technical parameters to ensure system compatibility and long-term reliability. NIPO manufactures gauge hatches in a variety of standard sizes and pressure ratings. We utilize high-grade materials to suit different media. Detailed dimensional drawings and technical brochures are available to assist with your project planning. We also supply a comprehensive range of compatible tank accessories to complete your installation.

Partnering with a direct manufacturer offers distinct advantages over purchasing from standard distributors. NIPO focuses on manufacturing excellence. We deliver direct-to-buyer benefits that enhance both project quality and budget efficiency.
Our strict quality control system guarantees reliability in the field. Every gauge hatch undergoes 100% pressure testing and 100% material inspection before leaving our facility. We are fully transparent in our manufacturing processes. NIPO always welcomes third-party quality checking to verify our rigorous standards.
We understand that standard catalog items do not always meet complex project demands. NIPO prominently features the ability to produce custom hatches according to customer drawings. This non-standard customization capability is supported by an annual R&D investment of over 3 million RMB. This ensures we can engineer solutions for the most challenging applications.
With nearly 20 years of industry experience, NIPO has built a high international and domestic reputation. We successfully export 40% of our owned brands. This extensive experience allows us to optimize our production lines. We assure buyers of quick delivery times and highly reasonable factory-direct pricing without compromising on quality.
NIPO’s gauge hatches are deployed across a wide range of demanding industrial sectors. They play a critical role in maintaining safety, preventing vapor emissions, and ensuring regulatory compliance in volatile environments. In the petroleum and petrochemical industries, our products provide secure, non-sparking access for oil storage tanks, refineries, and fuel depots. For chemical processing, we utilize corrosion-resistant stainless steel hatches designed for aggressive chemical storage. Additionally, the energy and power sectors rely on our equipment for reliable gauging points on fuel and coolant tanks. We also offer durable, weather-resistant access ports for municipal water supply and treatment reservoirs.
Choosing the correct model is vital for operational safety and longevity. Consider the following key factors when specifying a gauge hatch for your facility. This ensures optimal performance and seamless integration.
| Selection Factor | Consideration Details |
|---|---|
| Tank Media Compatibility | Select materials (e.g., stainless steel vs. aluminum) based on the corrosiveness and volatility of the stored fluid. |
| Operating Pressure | Ensure the hatch rating matches the tank's internal pressure to maintain a secure, leak-proof seal. |
| Environmental Conditions | Specify all-weather or explosion-proof designs if the tank is exposed to extreme climates or hazardous zones. |
| Connection Sizing | Verify the flange size and drilling standard (ANSI, DIN, etc.) to guarantee a seamless and secure installation. |
