不锈钢活接头，不锈钢活结，不锈钢由任，不锈钢内外丝活结，内丝活接，不锈钢圆螺纹活接：
特点：不锈钢圆螺纹活接具有操作连接方便，连接牢靠、耐压能力高、密封性和反复性好、安装检修方便、工作安全可靠等特点。
工作原理：是将钢管直接切入管子而密封。用活接头时，活接是可以自由控制活动的，这就避免了对接的长管子不可活动的弊端。它与钢管连接时不需焊接，有利于防火、防爆和高空作业，并能消除焊接不慎带来的弊端。
广泛用途：炼油、化工、石油、天然气、食品、制药、仪器仪表等 。

Stainless steel unions, stainless steel unions, stainless steel unions, stainless steel inner and outer wire unions, inner wire unions, stainless steel round thread unions:

Features: Stainless steel round thread union has the characteristics of convenient operation and connection, reliable connection, high pressure resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc.

Working principle: The steel pipe is directly cut into the pipe and sealed. When using a union, the union can freely control the movement, which avoids the disadvantage that the long pipe that is butted is inactive. It does not need welding when it is connected with the steel pipe, which is conducive to fire prevention, explosion-proof and high-altitude operation, and can eliminate the disadvantages caused by inadvertent welding.

Wide range of uses: oil refining, chemical industry, petroleum, natural gas, food, pharmaceutical, instrumentation, etc.
