一、进口低温法兰截止阀概述

进口低温法兰截止阀，也叫LNG法兰截止阀，液氮法兰截止阀，液氧法兰截止阀，液氩法兰截止阀，液化天然气法兰截止阀，是指采用法兰的连接方式，用于低温液体（主要包括液氧、液氮、液氩、液态烃和液化天然气等LO2、LN2、LAR、LNG等）贮运设备的管理系统的截止阀，具有开关灵活、密封可靠的特点，也可用于其他低温和深冷介质的管理系统。

美国威盾VTON主要产品有进口低温法兰截止阀，进口低温短袖截止阀，进口低温长袖截止阀，进口低温不锈钢截止阀，进口低温焊接截止阀，进口低温法兰截止阀，进口LNG低温截止阀，进口液氮截止阀，进口液氧截止阀，进口液化天然气截止阀，进口低温深冷截止阀等。主要用于乙烯，液化天然气装置，天然气LPG LNG储罐，接受基地及卫星站，空分设备，石油化工尾气分离设备，液氧、液氮、液氩、二氧化碳低温贮槽及槽车、变压吸附制氧等装置上。

Low temperature flange globe valve, also known as LNG flange globe valve, liquid nitrogen flange globe valve, liquid oxygen flange globe valve, liquid argon flange globe valve, and liquefied natural gas flange globe valve, refers to the globe valve used in the management system of low-temperature liquid (mainly including liquid oxygen, liquid nitrogen, liquid argon, liquid hydrocarbons, and liquefied natural gas, etc. LO2, LN2, LAR, LNG, etc.) storage and transportation equipment, which adopts a flange connection method. It has the characteristics of flexible opening and reliable sealing, and can also be used in the management system of other low-temperature and cryogenic media.

VTON's main products include low-temperature flange globe valves, low-temperature short sleeved globe valves, low-temperature long sleeved globe valves, low-temperature stainless steel globe valves, low-temperature welding globe valves, low-temperature flange globe valves, LNG low-temperature globe valves, liquid nitrogen globe valves, liquid oxygen globe valves, liquefied natural gas globe valves, low-temperature cryogenic globe valves, etc. Mainly used in ethylene, liquefied natural gas equipment, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, low-temperature storage tanks and tankers for liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide, and pressure swing adsorption oxygen production equipment.
