Product definition : Manhole operation well refers to a product that provides an underground space for installing equipment to transport and manage oil products at gas stations. The equipment includes liquid level meters, oil pumps, oil filling manhole covers and other equipment. It is a buried concealed engineering product. Application occasions: The application occasions are first-level explosion-proof areas, and open flame construction is strictly prohibited during operation. Pre-requisites: As a concealed engineering product in a Class I explosion-proof area, its design service life should be greater than 30 years, and its safety and explosion-proof performance must be certified or tested by a third-party independent organization.
Application: This application occurs in the first-level explosion-proof area. Hot work is strictly prohibited during operation. Prerequisite: As a concealed engineering product in a Class I explosion-proof area, its design service life should be more than 30 years. Safety and explosion-proof performance need to be certified or tested by a third-party independent organization. Applicable projects: used for new construction and expansion projects of gas stations, and for load-bearing tank areas and non-load-bearing tank areas. Buried depth: The distance from the bottom sealing flange surface of the load-bearing tank area and the non-load-bearing tank area to the ground of the gas station should be ≥1000mm.

The number of intermediate heightening connecting rings can be customized according to project requirements.
Product structure type: The bottom of the product has an external convex flange connection surface. The assembly and connection of various components adopt a modular connection method. The wall thickness of the product is 10mm, the maximum outer diameter is Φ1500mm, the operable internal space diameter is Φ1350mm, and the operable space height is 880mm. The overall height of the product can be adjusted according to the burial depth. Product structure composition: The product consists of SMC manhole operation well-cavity, shoulder, neck ring, sub-cover, pipe wall sealing component, leak-proof sealing component and stainless steel connector. Product material composition: SMC manhole operation well cavity, shoulder, neck ring and sub-cover are made of thermosetting SMC composite materials. The pipe wall sealing component and leak-proof sealing component are made of EPDM rubber, and all components are connected with 304 stainless steel bolts and nuts.
Product load capacity: >20 tons (load-bearing type); >1.5 tons (non-load-bearing type) Operating temperature range: -40°C to 100°C. Implementation standard: Enterprise standard Q/ZRS07-2013. Implementation of explosion-proof standard: GB 25286.1-2010, explosion-proof model: Ex IIAT3
