Product introduction Product name: thermal insulation manhole cover

Material: stainless steel SUS304 304L 316L.

Pressure range: up to 0.3mpa working pressure,

Surface treatment: surface mirror polishing (Ra≦0.8um) matt sandblasting pickling

Features: It belongs to the quick-opening pressure manhole, which can be welded on the side of the tank. The product design is beautiful and durable.

Product application: pharmaceutical, food, dairy, beer, chemical, petroleum, electrical fluid equipment, mechanical equipment, tank equipment and other industries.

Insulation manhole refers to the opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. It is mainly composed of short tube section (or short tube), flange and manhole cover with handle. For safety inspection, the number of manholes required for pressure vessels and their small size are shown in "Inspection Holes". Manhole materials are carbon steel and stainless steel. Manholes are divided into normal pressure and pressure manholes according to the pressure condition; manholes are divided into circular, oval and rectangular manholes according to shape, and rectangular manholes are only suitable for atmospheric pressure equipment; manholes are divided into horizontal manholes according to the installation position and vertical installation of manholes; the fixing methods of manhole covers include swivel cover and hanging cover; the speed of manhole opening is ordinary and quick-opening, and the structure and size of manholes are generally standardized.
