Brief:General sanitary stainless steel elliptical manholes are set in high pressure vessels, such as boiler drum, it belongs to the internal pressure seal, sealing surface in the container, the pressure is more high-density cover pressure is greater, the sealing effect is better, not like ordinary manhole sealing surface only by bolt fastening. Based on this sealing form, it can only be designed as an oval shape
Brief:Stainless steel manhole is installed on top of the tank safety emergency ventilation device, usually with flame damper, using mechanical breather valve, can avoid the accident caused sharp overpressure or vacuum in tank and tank damage and accident, security fire effect, is to protect the safety of tank device, especially suitable for the storage of materials with nitrogen gas cap vault atmospheric tank. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safe and reliable, etc.
Brief:Sanitary stainless steel outward open pressure manholes are used on the top or side of pressure tanks and containers. Pressure 0.05-0.5mpa, manhole cover material used for 304, 316L, especially in food, beer, dairy products, chemical containers and other industries. The pressure vessel also adopts fast open structure, easy to open, safe, practical and beautiful appearance.
Brief:Sanitary manhole for negative pressure manhole, made of SUS304,316L, can meet the special requirements of various media in the field of food, biological pharmaceutical, can be used in dairy products, beer, food, beverage, pharmaceutical, biological engineering and other industrial fields. Atmospheric pressure type, pressure type with viewing mirror, hand wheel type, rectangle, ellipse, ellipse with mirror, hand hole, square, etc.; Material specifications can be produced according to customer requirements. Also according to the customer to map, sample processing non-standard manhole.
Brief:Stainless steel sanitary filter cylinder are all made of high quality 304 or 316 l stainless steel materials, each filter are through strict selection and elaborate manufacture, ensure complete streamlined design and free of cracks, has the good surface and the maximum corrosion resistant ability, prevent bacterial contamination in order to achieve quality standards, hygiene level filter sleeve of unique structure, The inside and outside surface of each sleeve has no dead Angle, can be completely removed and washed, easy to operate
