All valves are to be supplied with butt-weld end connections as specified.
所有截止阀按要求为对焊端连接。
The weld end is formed from Nickel and Chromium with a limited amount of additional elements.
该焊接端由镍和铬及有限量的其它元素形成。
The weld end has a coefficient of thermal expansion, which is not between the values for the coefficients of thermal expansion for the discharge end and the base electrode.
该焊接端具有一个热膨胀系数，其不在该放电端和基本电极的热膨胀系数的值之间。
More specifically, the weld end has a coefficient of thermal expansion which is greater than the coefficients of thermal expansion for the discharge end and base electrode.
更具体地，该焊接端的热膨胀系数大于该放电端和基本电极的热膨胀系数。
