不銹鋼管ba標準是什麼

『壹』 不銹鋼級別中EP級、BA級、AP級、MP級都是什麼意思，分別用在什麼地方

AP：酸洗管(Anneal treatment & Passivation) /(Acid pickling)
MP: 機械研磨處理或稱機械拋光 (Mechanical Polish)
BA：光輝專燒鈍處理或稱光輝退火 (Bright Anneal treatment)/(Bright Annealing)

『貳』 BA級不銹鋼管件和Ep級不銹鋼管件區別在哪

不銹鋼的BA或EP級，指不銹鋼的表面處理工藝。其實它本身並不是「級」，只是習慣上因其加工復雜程度不同而被稱為XX級。

AP：酸洗管(Anneal treatment & Passivation) /(Acidpickling)

MP：機械研磨處理或稱機械拋光 (Mechanical Polish)

BA：光輝燒鈍處理或稱光輝（光亮）退火 (Bright Anneal treatment)/(Bright Annealing)

EP：在BA管基礎上對內表面做電化學拋光（電解拋光）

CP/AP：熱處理後化學拋光;

『叄』 不銹鋼食品管BA表面是什麼意思

不銹鋼BA管――BrightAnnealedtube(真空光亮退火管),它是氣氛保護熱處理(BrightAnnealed)的簡稱,又叫:不銹鋼BA管,潔凈管,光亮退火管,無縫管. BA表面的定義來自於美國標准ASTM A480 和歐盟標准EN10088。見下列英文解釋。

The most common definitions of these surface finishes are provided by ASTM A480 and EN 10088. In both cases it is the cold rolled manufacturing method that is specified rather than specific, measurable characteristics about the surface. We have used ASTM A480 as an example:

ASTM A480:

No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish. This non-directional finish is favourable for the retention of lubricants in deep drawing applications.

No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically proced by imparting a final light cold-rolled pass using [large diameter] polished rolls. This general-purpose finish is more readily polished than No 1 or 2D finishes. Proct with 2B finish is normally supplied in the annealed plus lightly cold-rolled condition unless a tensile-rolled [harder and stronger] proct is specified.

Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically proced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling ring annealing.

2B

2B is the most widely used stainless steel surface finish. It is especially common in instrial, chemical and food processing applications such as process vessels and tanks. It is also used in some architectural applications that will not be closely examined for uniformity of finish such as downpipes and gutters.

When specifying this finish think about these attributes:

• 2B is the most economical finish

• It is highly corrosion resistant because it has been chemically pickled and is smooth

• Over broad areas and between batches etc., it is not uniform and may not match in appearance

• It has been proced in the mill and can't be matched after fabrication

• It if often protected by plastic films until final cleanup and commissioning

2D

2D is used around the world in applications where its low reflectivity is important. The largest application is in roofing materials. The surface is rougher than 2B and retains lubricants better making it appealing for deep drawring. 2D surfaces are not designed for appearance so the limitations on matching of weld and other surface damage is not as critical. Railcars are a typical example where thicker sheet and ongoing abrasive damage make the rougher 2D a suitable finish.

When specifying this finish think about these attributes:

• 2D is not commonly available in Australia

• It is highly corrosion resistant because it has been chemically pickled and is relatively smooth

• Over broad areas and between batches etc., it is not uniform and may not match

• It has been proced in the mill and can't be matched after fabrication。

  Bright Annealed (BA)

The classic use of a BA finish is domestic: the interior of a dishwasher or clothes washing machine. In the clothes washer, it also provides a smooth, non-abrasive surface for the clothes to slide around. The mirror like surface is also used in road mirrors where a precise image is not required.

When specifying this finish think about these attributes:

• BA is common in some grades and thicknesses, but not all

• It is highly corrosion resistant because it is very smooth

• Different batches may not match

• It is has been proced in the mill and can't be exactly matched after fabrication although a mechanical mirror polish can be close.

『肆』 不銹鋼拋光管 EP BA AP 級代表什麼程度

AP、BA光亮退火光潔度<0.6um，EP電解拋光光潔度<0.2um。

1、EP：電解研磨處理

通過電化學拋光，可以極大的提高表面形態及及結構，使表層面積得到極大的程度的減少。表面是一層封閉的、厚厚的氧化鉻膜。能量接近合金的正常水平，同事介質數量也會降為最少。

微電子、光電子和生物制葯等行業對傳輸敏感或腐蝕性介質的高純、潔凈管道系統一般都採用光亮燒鈍(BA)、電解拋光(EP)產品。

2、BA：光亮固溶處理或稱光亮退火；

在加氫或真空狀態高溫熱處理，一方面消除內應力，另一方面在管道表面形成一層鈍化膜，以改善形態結構，減少能量水平，但不會提高表面粗糙度。

3、AP：酸洗管

管道經過酸洗或鈍化，不會提高表面粗糙度，單可以去除殘存的顆粒，降低能量水平，但不會減少介層數量。

不銹鋼拋光亮度等級

目測法，將拋光後零件 表面的光亮度分為5級：

1級：表面有白色氧化膜，無光亮度；

2級：略有光亮，看不清輪廓；

3級：光亮度較好，能看出輪廓；

4級：表面光亮 ，較清晰地看出輪廓 (相當於電化學拋光的表面質量)；

5級：鏡面般光亮。
