butt-weld

基本解释

Some crack extension probably developed from the unfused section of the butt weld across the thickness of the stiffener during transport and erection.
有些裂纹可能在运输和安装过程中就从加劲肋对接焊未熔透处开始发展。
This indicated that the fracture had initiated at the unfused butt weld in the longitudinal stiffener.
研究表明裂纹是从纵向加劲助未熔透的对接焊缝中起始的。
Body ? streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives.
阀体?流线形流道，最大限度减少压降。对焊、缩喉管或法兰连接端口几种可供选择的连接方式。
Turbulence, erosion and pressure drop are minimized.Flanged End-Crane cast steel gate valves are available in flanged end and butt weld ends.
所有阀盖构件都是铸件，并且按照严格的一致的公差标准进行抛光，使得阀体与阀杆能够准确校准，密封更加容易。
Body: Strong construction assures maximum safety over the recommended pressure and temperature range. Both flange and butt weld ends are available.
阀体：坚固耐用的结构，确保在相应的压力温度等级范围内的安全性。可提供法兰和对焊两种连接方式。
