Product Description
Our factory has 15 years of in-depth experience in fluid equipment manufacturing. This Stainless Steel Tank Manhole Cover is a dedicated maintenance opening device for storage tanks and vessels, with a working pressure of ≤0.1MPa, requiring no pressure vessel qualification. It adapts to cleaning, inspection, and maintenance needs for various atmospheric working conditions. The Stainless Steel Tank Manhole Cover is installed on the top or side of storage tanks. The body made of stainless steel is corrosion and rust resistant, adapting to medium environments in multiple industries such as food, pharmaceutical, and chemical. The atmospheric design not only has lower cost but also more convenient operation, making it a basic standard for atmospheric vessel maintenance. Our factory has a monthly production capacity of 1-2 million RMB. Standard product lead times are determined by quantity, on-time delivery is ensured through contracts, and photo and video progress updates can be provided during production.
This Stainless Steel Tank Manhole Cover comes in 304 general-purpose model and 316/316L high-corrosion dedicated model. Seals are made of materials such as PTFE Teflon and EPDM. Structures include swing cover and quick opening types. Sizes are mainly DN400-DN600, with temperature resistance of -20℃~150℃. The equipment has reliable sealing, preventing medium leakage and external contamination. The quick opening type allows single-person rapid opening and closing, adapting to frequent operation. For model selection, choose material based on medium and structure based on operation frequency. During installation, flange surfaces must be flat with bolts tightened diagonally. During maintenance, regularly inspect sealing surfaces and gaskets. For sanitary scenarios, choose dead-angle free mirror polished models. It is strictly prohibited for use in pressurized vessels. We support OEM/ODM and can manufacture based on technical drawings or prototypes. MOQ is not limited, and different models can be mixed in one minimum order quantity.

Packaging & Shipping
Export packaging uses pallets and wooden cases. Each Stainless Steel Tank Manhole Cover is first individually wrapped for protection, with flange surfaces and sealing surfaces additionally protected to prevent scratches and deformation during transportation, then placed in a wooden case. The entire batch is palletized and secured, with markings such as model, quantity, gross weight, and dimensions labeled outside the cases. We support both EXW and FOB trade terms. EXW means the buyer picks up the packaged products at the factory; FOB means the factory covers transportation to the port and customs clearance costs.
Payment Terms
Standard Stainless Steel Tank Manhole Covers follow the conventional payment process of 30% advance payment + 70% balance payment; custom products use 50% advance payment + 50% balance payment. Bulk orders are eligible for discounts, determined on a per-order basis. We accept payment in US dollars and RMB. The lead time for repeat orders is determined by the product order. The payment process is standardized and transparent, with each payment corresponding to a formal contract and commercial invoice.
