butt weld

基本解釋

Some crack extension probably developed from the unfused section of the butt weld across the thickness of the stiffener during transport and erection.
有些裂紋可能在運輸和安裝過程中就從加勁肋對接焊未熔透處開始發(fā)展。
This indicated that the fracture had initiated at the unfused butt weld in the longitudinal stiffener.
研究表明裂紋是從縱向加勁助未熔透的對接焊縫中起始的。
Body ? streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives.
閥體?流線形流道，最大限度減少壓降。對焊、縮喉管或法蘭連接端口幾種可供選擇的連接方式。
Turbulence, erosion and pressure drop are minimized.Flanged End-Crane cast steel gate valves are available in flanged end and butt weld ends.
所有閥蓋構(gòu)件都是鑄件，并且按照嚴格的一致的公差標準進行拋光，使得閥體與閥桿能夠準確校準，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.
閥體：堅固耐用的結(jié)構(gòu)，確保在相應(yīng)的壓力溫度等級范圍內(nèi)的安全性?？商峁┓ㄌm和對焊兩種連接方式。
