Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are bed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Double submerged arc welded (DSAW) pipe is welded pipe whose longitudinal butt joint is welded in at least two passes, one of which is on the inside of the pipe; the welds are made by heating with an electric arc between the bare bl electrode. Pressure is not used. Filler bl for the welds is obtained from the electrodes. For diameters above 36 inches, double seam welded pipe is specified as an alternative in API 5L. This has two longitudinal seams 180° apart, bed by the SAW process. Finished pipes are normally 40 feet (12 m) and occasionally 60 feet (18 m) long, depending on the capacity of the pipe mill and the ease of transport to the pipeline.
德國VOITH(福伊特)液力偶合器的工作原理以液體為工作介質(zhì)的一種非剛性聯(lián)軸器，又稱液力聯(lián)軸器。液力偶合器的泵輪和渦輪組成一個可使液體循環(huán)流動的密閉工作腔，泵輪裝在輸入軸上，渦輪裝在輸出軸上。動力機(內(nèi)燃機、電動機等)帶動輸入軸旋轉(zhuǎn)時，液體被離心式泵輪甩出。這種高速液體進入渦輪后即推動渦輪旋轉(zhuǎn)，將從泵輪獲得的能量傳遞給輸出軸。最后液體返回泵輪，形成周而復始的流動。液力偶合器靠液體與泵輪、渦輪的葉片相互作用產(chǎn)生動量矩的變化來傳遞扭矩。它的輸出扭矩等于輸入扭矩減去摩擦力矩，所以它的輸出扭矩恒小于輸入扭矩。液力偶合器輸入軸與輸出軸間靠液體聯(lián)系，工作構(gòu)件間不存在剛性聯(lián)接。液力偶合器的特點是：能消除沖擊和振動；輸出轉(zhuǎn)速低于輸入轉(zhuǎn)速，兩軸的轉(zhuǎn)速差隨載荷的增大而增加；過載保護性能和起動性能好，載荷過大而停轉(zhuǎn)時輸入軸仍可轉(zhuǎn)動，不致造成動力機的損壞；當載荷減小時，輸出軸轉(zhuǎn)速增加直到接近于輸入軸的轉(zhuǎn)速，使傳遞扭矩趨于零。液力耦合器的傳動效率等于輸出軸轉(zhuǎn)速與輸入軸轉(zhuǎn)速之比。一般液力偶合器正常工況的轉(zhuǎn)速比在0.95以上時可獲得較高的效率。液力偶合器的特性因工作腔與泵輪、渦輪的形狀不同而有差異。它一般靠殼體自然散熱，不需要外部冷卻的供油系統(tǒng)。如將液力偶合器的油放空，偶合器就處于脫開狀態(tài)，能起離合器的作用。
OC 6000e DCS可以確保系統(tǒng)安全、高效地運行。先進的控制和優(yōu)化解決方案的無縫整合技術(shù)進一步提高了機組運行效率，降低了計劃外強制停機損失，延長了維護周期，改進了機組的可靠性和可利用率，并最大程度地減少了運行成本。
