隔離材料描述翻譯-中英版

2.圖紙

根據(jù)買方的圖紙和說明書進(jìn)行隔離材料的安裝

某些制造商的圖紙，要求使用特殊的方法對(duì)隔離材料進(jìn)行，這些圖紙的要求優(yōu)先于本標(biāo)準(zhǔn)。

3.工作范圍

施工由承包商執(zhí)行。

隔離材料的范圍，油箱的隔離材料的施工操作或者具體工作以及管道輸送部分，在供應(yīng)商圖紙和說明書中進(jìn)行描述。

3.1    承包商進(jìn)入集裝箱或者室內(nèi)貯存隔離板加以管理和保存。

4.材料和工藝

如果沒有另作說明，全部的法蘭和閥件必須進(jìn)行隔離， ( 如果法蘭節(jié)點(diǎn)、閥件等等要求不做隔離)。相連的管材隔離必

須從法蘭距離連接末端套筒，螺絲的移動(dòng)不得損壞隔離材料。

4.1    如果沒有另作說明，法蘭蓋板、閥件、盲板和出入孔等等必須是可移動(dòng)類型，并帶有快速釋放肘節(jié)柄。這些可移

動(dòng)的蓋板將由金屬片制成，由堅(jiān)硬的隔離板坯或者帶有鋼絲網(wǎng)的金屬墊片固定在金屬蓋板上。儀器上的覆蓋部分將備

有快速釋放肘節(jié)柄，全部其它蓋板采用自攻螺絲固定。

隔離蓋板可以延伸到相臨的隔離管材，距離至少大于隔離管材的厚度，但不小于2英寸。

4.2   配件、法蘭、閥件等等隔離材料的厚度與臨近的管材隔離材料相同。

4.3   除非另作說明，閥件上半部分的包裝材料必須安置在隔離蓋板的外邊。
4.4   隔離材料允許關(guān)管材的支架可以自由移動(dòng)。

4.5   隔離材料的施工不得在壓力測試或其它必要的試驗(yàn)之前進(jìn)行。 銘牌和檢查標(biāo)識(shí)不得被買方要求的可移動(dòng)蓋板材料

覆蓋。

4.6   在開始隔離作業(yè)前，被隔離的表面一定保持潔凈、干燥。

4.7   隔離作業(yè)的承包商，不允許在現(xiàn)場執(zhí)行任何設(shè)備焊接作業(yè)，或者接受管材的壓力測試。

4.8   隔離作業(yè)的要求是：在連接處沒有開口或者在缺口，盡可能獲得得光滑隔離效果。管材隔離的水平面縱向焊縫，

必須底于隔離材料的一半，避免在水或者液體的接觸。多層隔離的關(guān)節(jié)處必須交錯(cuò)安排布置。

4.9   不銹鋼鋼管的隔離素材不得有氯化物。

4.10  管材和油箱的隔離材料必須使用定距環(huán)從防止弛度或者移動(dòng)。 垂直的隔離必須在1.5到1.8米的距離通過大頭釘固

定

5.    標(biāo)準(zhǔn)

如果圖紙中沒有另加說明，必須符合附上的標(biāo)準(zhǔn)說明。

6.   物質(zhì)采購與供應(yīng)

全部承包商隔離作業(yè)需要的交付材料，必須由承包商購買并提供如巖棉、金屬覆層、鋼絲網(wǎng)、支承環(huán)和鉗子等等，在

合同定稿之前進(jìn)行確認(rèn)。

7.    隔離作業(yè)的條件

7.1   管材的隔離

7.1.1 總則

管材的隔離分成3 種類型：
-IN熱損失隔離
-SI 安全絕緣
- CO防凝結(jié)隔離
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.
