系列規格
| Designs | Y-Type, Simplex Basket, Duplex Basket |
|---|---|
| Nominal valve connection size | DN25 to DN500 |
| Pressure class / nominal rating designation | ANSI Class 150 to Class 300 |
| Materials (component scope as published) | WCB (ASTM A216), LCB, LCC (ASTM A352), F11, F22 (ASTM A182), CF8, CF8M (ASTM A351), F316, F316L (ASTM A182), F51/2205 duplex (ASTM A182), F53, F55/2507 super duplex (ASTM A182), C95400, C95800 aluminium bronze (ASTM B148), nickel-chromium alloy 625, nickel-copper alloy 400, nickel-molybdenum alloy C276 (ASTM B564) |
| Service temperature range | 0 to 200°C (ductile iron Y-type strainer, water/steam/gas media) |
| Particle retention range | The common strainer particle-retention range runs from 1 inch down to 40 micron (0.0016 inch), set by the choice of perforated metal, mesh or wedge-wire straining element. |
| Operation Modes | Continuous flow during element cleaning (duplex basket), Shutdown required for cleaning (Y-type, simplex basket) |
| Basket Construction | The basket or screen is the heart of the strainer; baskets are offered in stainless steel, nickel-copper alloy or brass across a wide range of perforations and mesh, removing solids from 1/2 inch and larger down to 40 microns. |
| Inspection and pressure-test standards | API 598 |
| design focus | Structural strength under line pressure, open area and flow distribution, differential pressure behaviour, ease of maintenance and element replacement |
| document basis | Selection, installation and maintenance guidance follows the FCI Engineering Specification for the Selection, Installation and Maintenance of Pipeline Strainers (Fluid Controls Institute, Pipeline Strainer Section, 2021). |
| vertical installation | On vertical piping a Y strainer must be installed with its screen pointing downward so sediment is trapped in the debris collection chamber; install the strainer with the debris chamber at the lowest possible position. |
| duplex purpose | Duplex/twin basket strainers exist for lines that cannot be shut down for basket cleanout: flow switches to the second basket while the first is removed, cleaned and replaced. |
| maintenance practice | Schedule cleaning from the established clogging rate: pressure gauges on each side of the strainer show when cleaning is required, and differential pressure switches can drive warning lights or alarms. |

訂購與文件
文件
請在詢問時一併說明您需要的文件組合——此結構的常見項目（材質證明、按所列檢驗標準的測試報告、尺寸圖）將於報價時確認並隨附供應。
報價
可直接報價的詢問應說明：公稱口徑與壓力額定、閥體與閥座材質偏好、端部連接、操作方式，以及含溫度的使用介質。本頁的典型值為基準參考範圍；具有約束力的數值於報價時確認。
樣品與供應
供應條件、訂購數量與交期按訂單議定——請在詢問時說明目的地國家與所需時程。
儲存與運輸
閥門儲存時應保護閥座與密封件免受紫外線、臭氧與變形影響，安裝前保留端面保護蓋；彈性體或 PTFE 閥座結構應避免長期戶外存放——閥座材料在陽光直射與冰凍條件下老化最快。
