不銹鋼人孔

人孔是安裝在儲罐頂上的安全應(yīng)急通氣裝置，通常與防火器、機械呼吸閥配套使用，既能避免因意外原因造成罐內(nèi)急劇超壓或真空時，損壞儲罐而發(fā)生事故，又有起到安全阻火作用，是保護儲罐的安全裝置，特別適用于貯存物料以氮氣封頂?shù)墓绊敵汗?。具有定壓排放、定壓吸入、開閉靈活、安全阻火、結(jié)構(gòu)緊湊、密封性能好、安全可靠等優(yōu)點。

垂直吊蓋帶頸平焊法蘭人孔HG21520-95規(guī)定了碳素鋼、低合金鋼制垂直吊蓋帶頸平焊法人孔的型式、基本參數(shù)、尺寸、技術(shù)要求和有關(guān)使用規(guī)定。本標(biāo)準(zhǔn)適用于公稱壓力PN1.0~1.6MPa、工作溫度根據(jù)材料類別限定在表3-2規(guī)定范圍內(nèi)的垂直吊蓋帶頸平焊法蘭人孔。

Stainless steel manhole

The manhole is a safety emergency ventilation device installed on the top of the storage tank. It is usually used in conjunction with a fire extinguisher and a mechanical breathing valve. It can prevent accidents from damaging the storage tank when a sudden overpressure or vacuum in the tank is caused by accidents. It has the function of safety and fire resistance, and is a safety device to protect the storage tank. It is especially suitable for the vaulted atmospheric tank whose storage material is topped with nitrogen. It has the advantages of constant pressure discharge, constant pressure suction, flexible opening and closing, safe fire resistance, compact structure, good sealing performance, safety and reliability.

Vertical sling cover with neck flat welding flange manhole HG21520-95 specifies the type, basic parameters, dimensions, technical requirements and related use regulations of carbon steel and low alloy steel vertical sling cover with neck flat welding manhole. This standard applies to manholes with vertical sling-neck flat-welded flanges with a nominal pressure of PN1.0~1.6MPa and a working temperature within the range specified in Table 3-2 according to the material category.

Manholes are divided into emergency pressure relief manholes, explosion-proof fire-resistance breathing manholes, tank top manholes, tank wall manholes and cored manholes. Manholes are generally made of 304, 316L stainless steel plate or carbon steel.
