隔离材料描述翻译-中英版
2.图纸
根据买方的图纸和说明书进行隔离材料的安装
某些制造商的图纸，要求使用特殊的方法对隔离材料进行，这些图纸的要求优先于本标准。
3.工作范围
施工由承包商执行。
隔离材料的范围，油箱的隔离材料的施工操作或者具体工作以及管道输送部分，在供应商图纸和说明书中进行描述。
3.1 承包商进入集装箱或者室内贮存隔离板加以管理和保存。
4.材料和工艺
如果没有另作说明，全部的法兰和阀件必须进行隔离， ( 如果法兰节点、阀件等等要求不做隔离)。相连的管材隔离必
须从法兰距离连接末端套筒，螺丝的移动不得损坏隔离材料。
4.1 如果没有另作说明，法兰盖板、阀件、盲板和出入孔等等必须是可移动类型，并带有快速释放肘节柄。这些可移
动的盖板将由金属片制成，由坚硬的隔离板坯或者带有钢丝网的金属垫片固定在金属盖板上。仪器上的覆盖部分将备
有快速释放肘节柄，全部其它盖板采用自攻螺丝固定。
隔离盖板可以延伸到相临的隔离管材，距离至少大于隔离管材的厚度，但不小于2英寸。
4.2 配件、法兰、阀件等等隔离材料的厚度与临近的管材隔离材料相同。
4.3 除非另作说明，阀件上半部分的包装材料必须安置在隔离盖板的外边。
4.4 隔离材料允许关管材的支架可以自由移动。
4.5 隔离材料的施工不得在压力测试或其它必要的试验之前进行。 铭牌和检查标识不得被买方要求的可移动盖板材料
覆盖。
4.6 在开始隔离作业前，被隔离的表面一定保持洁净、干燥。
4.7 隔离作业的承包商，不允许在现场执行任何设备焊接作业，或者接受管材的压力测试。
4.8 隔离作业的要求是：在连接处没有开口或者在缺口，尽可能获得得光滑隔离效果。管材隔离的水平面纵向焊缝，
必须底于隔离材料的一半，避免在水或者液体的接触。多层隔离的关节处必须交错安排布置。
4.9 不锈钢钢管的隔离素材不得有氯化物。
4.10 管材和油箱的隔离材料必须使用定距环从防止弛度或者移动。 垂直的隔离必须在1.5到1.8米的距离通过大头钉固
定
5. 标准
如果图纸中没有另加说明，必须符合附上的标准说明。
6. 物质采购与供应
全部承包商隔离作业需要的交付材料，必须由承包商购买并提供如岩棉、金属覆层、钢丝网、支承环和钳子等等，在
合同定稿之前进行确认。
7. 隔离作业的条件
7.1 管材的隔离
7.1.1 总则
管材的隔离分成3 种类型：
-IN热损失隔离
-SI 安全绝缘
- CO防凝结隔离
PURPOSE
The purpose of this Appendix is to describe the insulation work
2. DRAWINGS
Insulation shall be carried out according to the Purchaser's drawings and specifications
Certain manufacture's drawings may demand a specific method for the installation of the insulation. Those drawings will have
priority over standards.
3. SCOPE OF WORK
The Works shall be performed by the Contractor.
The extent of the Insulation, if refractory work or concrete work in the tank and piping section mention in the suppliers
Drawings and Specifications will be valid.
3.1 Contractor shall manage and keep insulation board into container or indoor storage.
4. MATERIALS AND WORKMANSHIP
All flange and valves shall be insulated if not otherwise specified (When a flange joint, valve etc. is specified not to be
insulated). The adjoining pipe insulation shall be closed with end sleeves at such a distance from the flanges that the removal of
the screws does not damage the insulation.
4.1 The cover for flanges, valves, blind flanges and manholes etc, shall be of removable type with quick release toggle
grips. These removable covers shall be made from metal sheets, lined with rigid insulation slabs or matting with wire netting
facing fastened to the inside of the metal cover. Covers for instrument parts shall be furnished with quick release toggle grips, all
other covers can be secured with self-tapping screws.
The insulation of covers shall extend over the adjoining pipe insulation for distance of at least the pipe insulation thickness, but
never less than 2 inch.
4.2 The thickness of insulation for fittings, flanges, valves etc. shall be the same as for the adjacent pipe insulation.
4.3 The upper part of the packing gland of valves shall be kept outside the insulation cover unless specified.
4.4 The insulation shall allow free movement of pipes on the supports.
4.5 The insulation must not be made before pressure and other necessary tests have been made. The name plates and
inspection marks shall not be covered or made by removable covers which request by purchaser.
4.6 The surface to be insulated must be clean and dry before starting the insulation work.
4.7 Welding at site by the insulation Contractor to any equipment or piping already pressure-tested and accepted is not
allowed.
4.8 The insulation is to be made in such a way that there will be no openings or gaps in the joints and that the smoothest
possible insulation is achieved. Longitudinal joints in horizontal pipe insulation shall be at the lower half to avoid water or liquids
get in to insulation. When there are several layers of insulation, the joints must be staggered.
4.9 The insulation material for stainless steel piping must be free of chlorides.
4.10 The insulation of pipes and tanks must be prevented from sagging or shifting by use of distance rings. Vertical
insulation shall be fixed with studs at a distance of 1.5 to 1.8 m.
5. STANDARDS
If not otherwise stated in the drawings, the guide lines of standard attached shall be followed.
6. MATERIAL PURCHASE AND SUPPLY
All materials are included in the Contractor's delivery and needed for the insulation work shall be purchased and supplied by the
Contractor as e.g. mineral wool, metal claddings, wire nets, support rings and clips etc. To be confirm before finalize the
contract.
