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:Sanitary manhole made of SUS304,316L, can meet the food, born in the pressure tank and the container has the top, the way to the inside of the container is closed right. The special requirements of various media in the pharmaceutical field, its smooth, seamless, automatic empting handicraft fluid channel is also very suitable for steam and local cleaning needs, in the manufacturing process in strict accordance with FDA requirements for quality control, the use of three-dimensional computer design, is made for GMP requirements. Manhole is used in dairy, beer, food, beverage, pharmaceutical, biological engineering and other industrial fields of large cans and containers。
