By improving the mechanical properties of the material and optimizing the structural design, the manhole cover and the well seat have a high degree of fit, a stable structure, and small deformation. The product will not produce deformation, displacement, or cracking during installation and use.
BETTER COVER's independently developed SMC composite material has high density, low water absorption (0.15mg) and good waterproof properties.
At the same time, the design of the sealing ring and structure achieves good sealing performance.
Some sewer covers may corrode due to exposure to hydrogen sulfide gas, water and salt, which may lead to cover failure in harsh environments.
Fat, oil and grease (FOG) in the oil separator can also lead to serious H2S production. H2S is converted into sulfuric acid by bacteria in the sewer system. The well cover materials BETTER COVER use will not change the structure or performance of the materials if they are used underground or in oil and gas environment for a long time. Strong even when exposed to corrosive environment.Service life exceeds 30 years.
Bridge structure design:Enhance compression resistance→ thereby achieving product lightweight.
BETTER COVER composite manhole cover is 1 / 4 of that of traditional manhole cover with the same volume, which can reduce the risk of back injury.Easy to use and operate by one person during installation and maintenance, saving labor costs.
The SMC composite manhole covers and frames independently developed and produced by BETTER COVER can be used for a long time at -50℃~+150℃, with a service life of over 30 years.
The R&D team of BETTER COVER can carry out customized development for products of different sizes, from product structure design, to mold design and manufacturing, and then to mass production of finished products. The core engineers have 20 years of industry experience.
Enhance compression resistance→ thereby achieving product lightweight
The manhole cover has strong sealing performance, a high degree of fit with the valve seat, a stable structure and small deformation. The sealing ring adopts a beveled cutting design, with a large contact surface.
The large-diameter φ900mm D400 E600 manhole cover was successfully developed, with a high fit between the cover and the seat ring, stable structure and small deformation
Composite materials are more abundant than cast iron and other metal resources, with higher cost performance. One-time molding, faster production process and lower manufacturing cost than cast iron products.
Backed by strong engineering and manufacturing capabilities, BETTER COVER provides continuous support from product development and production to installation and long-term operation.
