Some advantages of elliptical large-view manholes

Manholes are categorized into emergency pressure-relief manholes, explosion-proof flame-arresting breathing manholes, tank‑top manholes, tank-wall manholes, and core‑type manholes. Our company’s main manhole series include: rectangular insulated manholes, circular insulated manholes, steel manholes, atmospheric-pressure manholes, swivel‑cover plate type flat‑weld flange manholes, swivel‑cover manholes with butt‑weld flanges, vertical‑lift cover plate type flat‑weld flange manholes, horizontal‑lift manholes with butt‑weld flanges, horizontal‑lift plate type flat‑weld flange manholes, horizontal‑lift manholes with butt‑weld flanges, atmospheric‑pressure quick‑opening manholes with rotary handles, elliptical swivel‑cover quick‑opening manholes, coal‑dust purging ports, flat‑wall coal‑passage ports, round‑wall coal‑passage ports, round welded manholes, flue‑gas ash‑removal ports, square dampers (single‑axis, double‑axis, triple‑axis, quadriaxial, quinti‑axial), round dampers (electric, manual), explosion‑proof doors, gravity‑type explosion‑proof doors, fan inlet plenums, inclined‑surface explosion‑proof doors, and horizontally mounted gravity‑type explosion‑proof doors, among other products.

The manhole sight glass insulation jacket is made of flexible, high‑temperature‑resistant fabric; during installation and routine use, avoid cutting or scratching it with knives or sharp objects. When disassembling or reassembling, handle it gently to prevent accidental damage.

The water tank shall be equipped with a manhole, which shall have a lockable, sealed cover. The cover shall feature a recessed groove and be fitted with a sealing gasket, and it is recommended to install a transparent sight glass on the manhole cover. Return to homepage for more details.

The fermentation system primarily comprises fermentation tanks, sake‑clarification tanks, and yeast‑propagation equipment. The tank shells feature milled‑plate jackets fabricated from 304 stainless steel, with cooling media including sake and purified water. Each tank is equipped with a sight glass, a single inlet/outlet at the bottom, and a double‑acting vacuum valve and diaphragm pressure gauge at the top. It also includes a sealed sight glass, a backup venting port, an internal wash ball, and an external backup venting pipe. Additionally, the tank is fitted with a sterile sampling valve, a platinum resistance thermometer, and an 80‑type Lumi‑view illuminated sight glass. The upper head is cold‑rolled and elliptical, offering an aesthetically pleasing design with no dead zones for cleaning, and it incorporates a sampling port.

Definition of an aseptic tank: A blending tank, also known as a preparation tank or formulation tank, is a stainless-steel mixing and agitating vessel used to blend one or more ingredients according to specified process ratios. It is widely employed in various stages of production across industries such as dairy, pharmaceuticals, and biotechnology, and serves as essential equipment for preparing parenteral solutions and injectable formulations in the pharmaceutical sector. Typical system configurations include a drive unit, mechanical sealing assembly, temperature control system, illumination lamps, sight glasses, agitators, manholes and feed hatches, steam inlets, condensate outlets, product discharge ports, drain outlets, sampling ports, and 360° omnidirectional cleaning balls. Some models may also incorporate plate‑type filtration units, weighing and metering devices, level‑measurement systems, and recirculation loops.
