Graffiti manhole covers combine urban functionality with artistic expression, transforming mundane utility access points into vibrant public art. Typically made from cast iron or composite materials, these covers maintain structural

Composite manhole covers are mainly made of non-metallic materials such as glass fiber, resin, mineral powder, etc. Compared with traditional cast iron manhole covers, they have advantages such as anti-theft, corrosion resistance,

The surface of the ductile iron manhole cover is also treated with anti-rust asphalt paint. One advantage of ductile iron manhole covers is that due to the high strength and good toughness of ductile iron, ductile iron manhole covers are

The IR2 double infrared gas detectors are widely applied different industry applications,such as: tunnel industry, oil and gas tank farm, power industry and petrochemical industry, etc.

Industrial usage, anti-corrosion,waterproof,dustproof and explosion proof.

It is mainly used in petrochemical, natural gas exploration, pharmaceutical enterprises, power stations, aerospace industry, hangars, aircraft repair yards, chemical industry, highway tunnels, ammunition and explosives warehouses, paint

The pressure transmitter adopts high quality diffusion silicon sensor and the industrial 3051 anti-explosion case, using integrated circuit, output 4-20mA electric current signal and mod-bus digital signal.

It is the most popular pressure transmitter, its pressure diaphragm material is diffused silicon and the housing shell is stainless steel which is easy to install. It has high stability and reliability which could support remote
