YJTW 系列耐酸、耐高温压力表
YJTW Series Acid Resistant & High Temperature Resistant Pressure Meter
简介
本仪表广泛应用于石油、化工、化纤、冶金、电站等工业部门中对耐酸、耐高温有较高要求的工艺流程中测量各中流体介质的压力。
耐酸压力表的零件全部采用不锈钢材料制成，具有较强的耐腐蚀性能，适用于检测腐蚀性较强介质的压力和在外部腐蚀环境中使用。
耐高温压力表的零件全部采用不锈钢材料制成，导压系统采用焊接工艺，具有优良的耐腐蚀性能。适用于对腐蚀性较强的介质和锡钎焊工艺不宜采用的高温介质或温度较高环境中的压力检测。
Brief introduction:
This sort of meter is used to measure pressure of various liquid mediums, which are widely used in technique flows of industry departments, such as oil industry, chemical industry, chemical fiber, metallurgy, electricity station, etc, which require higher acid-resistant performance.
Parts of acid resistant pressure meter are all made of stainless steel material, so the meters acid-resistant performance is much better and can be used to measure pressure of medium with powerful corrosion.
Parts of high temperature resistant pressure meter are all made of stainless steel material, and welding technique is adopted in its pressure leading system, so the meters corrosion resistant performance is good. This sort of meters can be used to measure pressure of following mediums: medium with strong corrosion, high temperature medium that is not suitable for braze welding technique, or medium with high temperature.
