When nominal diameter of pipe is less than 100mm, allowable deviation is 1mm, when it is more than100mm, allowable deviation is 2mm. Full length allowable deviation shall be not more than 10mm. requirement for pipe connecting to power equipment178。 管道安裝時應在設備管口放置臨時隔離盲板，防止異物進入設備內。Temporary blind plate shall be placed at the equipment pipe end when pipeline installation in order to prevent foreign matter from entering the equipment.178。 動設備相連的管道,其固定焊口應遠離機器。For pipeline connecting to the power equipment, its fixed weld bond shall be away from the machine.178。 與轉動機器連接的管道，宜從機器側開始安裝，應先安裝管支架，使管子和閥門等重量和附加力矩不能作用在機器上。管道與機器連接前應在自由狀態(tài)下檢查法蘭的平行度和同軸度，允許偏差應符合下表規(guī)定：For pipeline connecting to rotary machine, installation shall be executed from the side of machine, and pipe supports shall be first installed to release weight of pipe, valve and additional torque to the machine.法蘭平行偏差徑向偏差及間距(mm)Parallel deviation, coaxial deviation and spacing of flange機器轉速rpm平行偏差徑向偏差間 距3000≤≤墊片厚度+3000～6000≤≤墊片厚度+6000≤≤墊片厚度+Equipment RPMParallel deviation Coaxial deviationSpacing3000≤≤Gasket thickness +3000～6000≤≤Gasket thickness +6000≤≤Gasket thickness +178。 管道系統(tǒng)與機器最終連接時，應架設百分表監(jiān)視機器位移，當小于或等于6000r/min時，；大于6000r/min時。When pipeline system and the machine finally get connected, dial gauge shall be erected to monitor the machine displacement. When the indicator value is less than or equal to 6000r/min, the displacement value shall be less than , and when indicator value is more than 6000r/min, displacement value shall be less than . requirement of stainless steel pipe178。 吊裝時必須采用尼龍吊帶繩 。Nylon sling shall be used for lifting work.178。 現(xiàn)場安裝時不允許直接接觸其它材質的管道、不得用鐵錘敲打。若發(fā)現(xiàn)管子表面有機械損傷時，必須修整光滑，并要進行酸洗鈍化處理。It is not allowed for pipe to get direct connection with other pipes for site installation, as well as no strike by the hammer. If mechanic damage is found on the pipe surface, finishing work shall be made and acidwashing passivation treatment shall be performed.178。 不銹鋼管應用機械或等離子方法切割。當用砂輪切割及磨坡口時，應采用專用切割片及砂輪片。Mechanical or plasma cutting shall be used for stainless steel. When cutting work or bevel ground is done by abrasive wheel, special cutting blade or grinding wheel shall be adopted.178。 不銹鋼焊件坡口兩側各100mm范圍內,在施焊前涂以專用防護膏,防止焊接飛濺物沾污焊件表面。Before welding, weldment bevel and its both sides with 100mm shall be smeared with special protective paste to prevent spatters from attaching pipes.178。 不銹鋼管不準直接與碳鋼支架接觸，應在支架與管道之間墊入不銹鋼片、不含氯離子的塑料或橡膠墊片。It is not allowed for pipe to get direct connection with support. gasket, plastic or rubber gasket without chloridion shall be filled between support and pipe.178。 焊接時不準在母材料上引弧。接口焊接接時應避免臟物的影響和氧化膜的破壞。Arc strike on the raw material is not allowed when welding. Dirt and oxidation film damage shall be prevented when joint welding.178。 不銹鋼管道焊接完畢后，應用砂輪磨光機對焊縫表面的飛濺物進行打磨，然后涂上酸洗膏浸泡，用鋼絲刷進行焊縫清洗，最后用水進行沖洗，焊縫表面呈現(xiàn)金屬亮光色澤，通過監(jiān)理檢查確認后為合格。After pipe welded, spatters on the welds surface shall be ground with grinder, then smear pickling paster on it, and brush the surface with steel wire brush, flush it with water, till the welds surface appear metal base bright color. It can be eligible after being approved by management pany and the supervisor.178。 在本項目中的鋼管材質有好幾種，安裝前必須在管子上做好明顯標記，防止材料搞錯。There are various types of pipes in this project. Pipes shall be clearly marked before installation to prevent material misuse. requirement to special piping requirement to glass fiber reinforced piping178。 本工程玻璃鋼管道根據圖紙尺寸及規(guī)格采用工廠化預制，分段連接的，每節(jié)都帶有法蘭。施工中一定要保證法蘭處的密封，密封墊要放置正確，螺栓要對稱緊固，緊固力矩要適中。The glass fiber reinforced piping in this project is factory prefabricated as per the size and specification in the drawing, and connnected section by section, with flange for each section. During the construction, the sealing of joint at flanges must be ensured, the sealing gasket shall be placed properly, the bolts shall be fastened symmetrically with suitable torque.178。 如果需要調整管線的長度，可在非法蘭部位截開進行調整。調整合格后，在管端涂上膠合劑對口粘接，并在粘合接縫處加浸透膠合劑的玻璃布纏繞數層即可。注意使每層布都要纏緊，不得殘存氣泡，或產生脫層等現(xiàn)象，強度要達到原管道的強度。If the pipeline length needs to be adjusted,make cut on places where there is no flange. And after adjustment, binder shall be painted at pipe ends for pipe’s bonding,and then glass fabric that saturated with binder will be wound around the joint by several layers. Special attention shall be paid to have each layer wound tightly without any bubble left or layer separation, and the strength shall reach to that of original pipe.178。 ~，不宜過厚，便于膠結劑浸透粘牢。膠結劑應隨配隨用。膠結劑的固化劑有毒，配置膠結劑時應在良好通風場所進行，操作者須戴口罩及手套。The glass fabric should not be too thick, and appropriate thickness is ~, so as to have the fabric fully saturated with binder. The binder shall be formulated while using. For the curing agent of the binder is poisonous,so the binder shall be formulated in wellventilated places, and the operator must wear mask and gloves.178。 玻璃鋼管道切割，可采用機械切割，但不允許有分層和脫落現(xiàn)象。管子表面應平整，不允許起層，允許有由于玻璃布脫脂所形成的色澤深淺、氣泡和皺折，經加工修正后不得超過壁厚公差，內壁允許有輕微的皺紋。Mechanic cutting can be applied to glass fibe pipes, but layering and peeling are not allowed.
