HongTaivalve-Stainless steel full-view mirror vertical pressure manhole-size dn15-dn150-HTV-PM001

설명

The manhole is a safety emergency ventilation device installed on the top of the storage tank, usually used with fireproof and mechanical breathing valve, which can not only avoid accidents caused by sudden overpressure in the tank or damage to the storage tank during vacuum, but also play a safe fire resistance role, and is a safety device to protect the storage tank. Especially suitable for storage materials with nitrogen capped vault atmospheric tank, with constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safe and reliable.
Manholes have a variety of designs: such as round, oval, square, open inside, open outside, pressure type, atmospheric type. It can also be configured with sight mirror, all-glass view, etc., the internal and external surface polishing treatment, the accuracy can reach Ra 0.5um,Ra 0.8um, the external surface is usually polished, matte treatment, sandblasting treatment. The maximum pressure is up to 5.0bar. The material is SS304 SS316L, which is mainly used in various pressure vessels in food, wine, beverage, pharmaceutical and other industrial fields.

스테인리스 스틸 맨홀에는 압력 맨홀과 비압력 맨홀이 있으며, 그 중 비압력 탱크 맨홀은 SS304 또는 SS316을 제공할 수 있습니다. 주로 대기 저장 탱크 및 혼합 탱크와 같은 탱크 장비에 사용되어 탱크 상단의 공기를 제어하면서 액체 레벨을 확인하며 맨홀이 밀폐되어 공기 교환을 방지합니다. 맨홀은 일반적으로 탱크 상단에 설치되며, 맨홀의 크기는 적용되는 조건에 따라 달라집니다. 큰 맨홀은 고체를 추가하기 용이하고, 작은 맨홀은 액체나 분말을 추가하기 용이합니다.
맨홀 압력은 스테인리스 스틸 재질의 벽 두께와 플랜지 링의 두께에 따라 다르며 원형 맨홀, 사각형 맨홀 및 타원형 맨홀을 제공 할 수 있습니다. 다양한 고객 요구에 따라 호흡 밸브 맨홀로 유리 맨홀을 사용자 정의 할 수 있으며 표면은 샌드 블라스트 또는 거울 연마가 가능합니다.

Glass manholes are very convenient for observing tank materials. We can also install manholes with lights, which are slightly more expensive than other manholes, which are suitable for the installation of atmospheric tank tops. The functions are divided into fully enclosed, observable glass mirror type and observable glass mirror type with light.

Product Packaging Instructions：
