Details

Sealed well cover is a device used to cover underground wellheads with good sealing performance and protective function. It is mainly composed of cover plate, cover seat, sealing ring and other parts. The cover is usually made of high-strength materials, with pressure resistance, corrosion resistance and other characteristics, can effectively withstand external forces and heavy pressure, to ensure the safety and reliability of the wellhead. Manhole cover seat is usually made of reinforced material, with good support ability, can be stable fixed manhole cover, prevent its movement and sliding. The sealing ring is an important part of the sealing performance of the wellhead, usually made of high-quality rubber materials, with excellent abrasion resistance, aging resistance and other properties. The installation and maintenance of the sealing manhole cover is relatively easy, only need to place the cover plate on the top of the wellhead, and fixed by the cover seat, and then ensure that the sealing ring is intact. Sealed manhole covers are widely used in urban roads, drainage systems, water supply pipelines and other fields, providing a reliable guarantee for the normal operation of underground facilities and the safety of people's lives.

High standards

Strictly implement the National Standard of the People's Republic of China "GB/T23858-2009 Inspection Manhole Cover" and the European Standard EN124: 1994 "Standard for Drainage Covers and Manhole Covers for Vehicles and Pedestrians".

Lightweight

The resin manhole cover is only about one-third of the cast iron manhole cover, which is much lower than the weight of the cement manhole cover with the same load, which is convenient for transportation and installation, and greatly reduces labor intensity.

High strength

The composite well cover produced by high temperature and high pressure using the special SMC sheet film plastic for resin manhole cover, the highest test load is F900KN

Appearance

The surface pattern of the inspection manhole cover is exquisitely designed, and it can be customized according to user requirements and made into various colors to beautify the urban environment.

Anti-theft

The synthetic material has no recycling value and is naturally anti-theft; and is equipped with a locking structure to realize theft prevention of property in the well.

Weather resistance

The product uses high molecular weight and chemically stable polymer materials as raw materials. Through scientific formula, advanced technology, and perfect technical equipment, the product can be normal within the range of minus 50 degrees Celsius to 150 degrees Celsius. use.

High precision

Because the product is molded at high temperature, the gap between the cover and the seat is small, which overcomes the shortcomings of "running, jumping, and sounding" of cast iron and cement, and improves the road capacity and driving comfort.

Corrosion resistance

The product has been tested by the National Chemical Building Materials Testing Center and has corrosion resistance, acid and alkali resistance, and the anti-aging index has reached three levels or more, and the service life is long.

Good after-sales service

Strictly implement the product warranty policy under the premise of non-human damage and correct use.
