Mpɛn pii no, nsɛm a wɔakyerɛkyerɛ mu ne nneɛma a wɔkra no ka eyinom bom sɛ:

Surface class + scope (ID / OD / ID + OD) + botaeɛ mu Ra boɔ.

1. AP – Wɔde Annealed & Wɔayɛ no Pickled

AP twe adwene si so sɛ wobeyi scale ne weld heat tint afi hɔ na ama wɔanya base surface a ɛho tew, weldable, na corrosion-resistant. Nneɛma a wɔtaa de di dwuma:

• General mfiridwuma nhyehyɛe lines
• Adwinnade ne nhama a wɔde di dwuma
• Utility headers ne ɔhyew-sesafo nnwuma bi

Wɔ dade a ɛnyɛ den a ɛyɛ pɛpɛɛpɛ 304 ne 316 ho no, wɔde AP soro di dwuma kɛse ma mfiridwuma mu nsu, nsu a ɛyɛ hyew, mframa a wɔahyɛ no den, mframa a ɛnyɛ adwuma, ne nnuru a wɔde yɛ adwuma a wɔahyɛ da ayɛ pii.

Nneɛma a Ɛwɔ Afã So

• Uniform matte anaa dull finish, a enni scale a emu yɛ duru anaasɛ ɔhyew tint a ɛda adi pefee.
• Mfinimfini roughness wɔ medium level, a ɛfata ma dodow no ara mfiridwuma media ne gyinapɛn ahotew akwan.

• Nsuo afiri ne nnwinnadeɛ mmeaeɛ a ɛda adi a ɛhia sɛ wɔwie no daa

Wɔ 316L pɛpɛɛpɛ stainless dade nsukorade, MP mu soro a wɔaka abom ne Ra anohyeto a ɛfata yɛ nhyehyɛe a wɔtaa yɛ ma ahotew ne high-bo a ɛkorɔn nsɛm ho amanneɛbɔ nnwuma.

Surface ne Roughness Su ahorow

• Wobetumi asiesie surface sɛ fine-ground, brushed, anaa mirror-te sɛ, ɛkari pɛ wɔ ahotew ne ne hwɛbea.
• Typical emu roughness botae ahorow ma pɛpɛɛpɛ tubes:

Mfiridwuma mu mfiri a wɔde yɛ polish: emu Ra ≈ 0.6–0.8 μm

Ahotew mfiri a wɔde yɛ polish: emu Ra ≈ 0.4–0.6 μm

Saa gyinapɛn ahorow yi gu ahorow wɔ gyinapɛn ahorow, nnwumayɛbea nneyɛe, ne afifide tumi mu, na wɔtaa kyerɛw sɛ "MP mu soro, Ra Ennu anaa ɛne X μm yɛ pɛ" a wɔde ɔkwan a wɔakyerɛkyerɛ mu a wɔfa so susuw ne beae a ɛwɔ.

Akyinnye biara nni ho sɛ mfiri a wɔde yɛ polishing no yi nneɛma bi fi hɔ. Wɔ teateaa-fasu ne tight-tolerance tubes ho no, ɛsɛ sɛ wodi kan yɛ OD, WT, ne ovality allowances ho nhyehyɛe sɛnea ɛbɛyɛ a precision tubes a wɔawie no bɛkɔ so atra tolerances a wɔakyerɛ no mu.

4. EP – Wɔde anyinam ahoɔden ayɛ

EP de electrochemical dissolution of micro-peaks di dwuma de yɛ emu fã a ɛyɛ torotoro, ɛyɛ den, na ɛma ahotew ne nkae sohwɛ tu mpɔn. Nneɛma a wɔtaa de di dwuma:

• Nsuo a ɛho tew a ɛkorɔn-hotew ne ultra{1}}ahotew nhyehyɛe
• Semiconductor ne ɛlɛtrɔnik-grade nnuru a wɔde fa nsu mu
• High-end nnuru ne bioprocess piping
• Lines a anohyeto katee wɔ particles, extractables, ne ahotew validation aba

Wɔ nhyehyɛe a ɛkorɔn-ahotew mu no, 316L EP pɛpɛɛpɛ dade a ɛnyɛ den nsukorade yɛ gyinapɛn nkabom: grade no boa nsɛe a ɛko tia ne ahotew nnuru, bere a EP mu nneɛma boa ahotew botae ahorow a emu yɛ den.

Surface ne Roughness Su ahorow

• Mfinimfini no bɛyɛ mmerɛw wɔ micro-scale no so, a stagnation points ne micro{1}}pits kakraa bi na ɛwɔ mu.
• Mpɛn pii no, emu roughness botae ahorow:

EP a ɛkorɔn-hotew / ahotew: emu Ra ≈ 0.3–0.4 μm

Ahotew a ɛkorɔn (sɛ nhwɛso no UHP): emu Ra a ɛba fam kodu ≈ 0.25 μm anaa nea ɛba fam, a egyina tumi a wɔde yɛ adwuma ne gyinapɛn ahwehwɛde ahorow so

Wɔtaa kyerɛkyerɛ EP mu ne ahotew, nea ɛyow, nneɛma a wɔde kyekyere nneɛma a ɛho tew, ne nkrataa; ɛyɛ ahotew a ɛkorɔn-ahotew sohwɛ nhyehyɛe a edi mũ no fã sen sɛ ɛbɛyɛ ahosiesie a wɔde wie nkutoo.

1. AP – Nnwuma ne Nnwinnade Nhyehyɛe a Wɔtaa de Di Dwuma

Nsɛm ho amanneɛbɔfo: mfiridwuma mu nsu, nsu a ɛyɛ hyew, mframa a ɛnyɛ adwuma, nnuru a wɔde di dwuma daa

Nhyehyɛe ahorow: utilities, adwinnade nkate nhama, control sɛnkyerɛnne piping

Esu: twe adwene si corrosion resistance ne weldability so; anohyeto biara nni hɔ a ɛboro so wɔ nkae a ɛwɔ mu no ho.

Octal Pipe de AP mu 304 ne 316 pɛpɛɛpɛ stainless dade tubes ma pii utility ne instrumentation amansin, bom standardized pickling / passivation ne dimensional nhwehwɛmu kata dodow no ara mfiridwuma adwumayɛ tebea.

2. BA – Ɔkwan a Wɔfa so Tew ne Nea Ɛda Hɔ-Ntrɛwmu a Ɛyɛ Nkate

Nsɛm ho amanneɛbɔfo: nsuo a wɔyɛ ho adwuma, aduane bi / ankorankoro hwɛ ho nsɛm ho amanneɛbɔ, mframa a ɛnyɛ adwuma anaa ɛbɔ ho ban

Esu: ɛho tew na ɛyɛ pɛ sen AP, ɛtew kɔla a ɛsakra ne ɔfasu so sintɔ ahorow so, bere a ɛkora ti so ma akyiri yi polishing anaasɛ electropolishing sɛ ɛho hia a.

Wɔ Octal Pipe deliveries mu no, wɔtaa paw BA 304L ne 316L precision tubes ma afifideɛ piping a ɛho tew ne nnwinnadeɛ nkitahodi nhama a ɛwɔ baabi a ɛho tew a ɛwɔ soro, sɛnea ɛte, ne daakye nsakraeɛ a ɛyɛ mmerɛw nyinaa fa ho.

3. MP – Ahotew ne Mmerewa-sɛ-Ahotew Nhyehyɛe

Nsɛm ho amanneɛbɔfo: nnuan ne anonne a wɔde yɛ nneɛma, nnuru a wɔde yɛ nnuru, nnuru pa a ne bo yɛ den-

Nhyehyɛe ahorow: ahotew piping, CIP / SIP loops, production lines a wɔtaa siesie kyinhyia

Esu: wɔakyerɛkyerɛ mu Ra anohyeto ahorow mu, wɔatew nkae a wɔkora so, ne weld nsakrae a ɛyɛ mmerɛw de boa ahotew ne validation.

Wɔ sanitary 316L precision stainless steel tubes ho no, Octal Pipe taa de MP mu nneɛma ne ahotew gyinapɛn a ɛfata te sɛ ASTM A270 bom na ɛde Ra sɔhwɛ aba ne ɔfasuo ayaresa ho kyerɛwtohɔ ma de boa adetɔfoɔ a wɔgye tom wɔ nnuru ne aduane nnwuma mu.

4. EP – Ahotew Nhyehyɛe a Ɛkorɔn-Ahotew ne Nea Ɛkorɔn-Ahotew Nhyehyɛe

Nsɛm ho amanneɛbɔfo: nsuo a ɛho tew a ɛkorɔn-a ɛho tew kɛse, ɛlɛtrɔnik-nnuru, biologics, mframa a ɛho tew kɛse-

Nhyehyɛe ahorow: semiconductor process lines, electronic-grade nnuru kyekyɛ, high-end nnuruyɛ ne bioprocess platforms

Esu: anohyeto a emu yɛ den a wɔde ma wɔ nneɛma nketenkete, nneɛma a wotumi yi fi mu, ne bioburden ho; mpɛn pii no "MP + EP" a wɔaka abom a Ra ne ahotew ho nkrataa a ɛyɛ den ka ho.

Wɔ high-ahotew ne UHP nnwuma mu no, Octal Pipe taa de EP pɛpɛɛpɛ tubes a ɛwɔ 316L mu a ɛwɔ nhyehyɛe nkɔnsɔnkɔnsɔn a ɛyɛ hann annealing, mfiri pre-polish, ne electropolishing, a batch-level Ra amanneɛbɔ ne ahotew kyerɛwtohɔ boa de di semiconductor ne bioprocess adetɔfo ahwehwɛde ahorow ho dwuma.

Wɔ nkyerɛkyerɛmu ne adetɔ nkrataa mu no, ɔfa a ɛwɔ soro ma pɛpɛɛpɛ / high-precision stainless steel tubes no taa ka bom:

1. Surface adesuakuw– AP, BA, MP, anaa EP
2. Baabi a ano pem– emu (ID), akyi (OD), anaa ID+OD
3. Mfinimfini mu a ɛyɛ den– Ra anohyeto ne unit (μm / μin), a sampling frequency anaa batch amanneɛbɔ ahwehwɛde ka ho
4. Nkyerɛkyerɛmu a ɛkyerɛ sɛnea ɛte– te sɛ brushed, mirror polished, anaa matte de kyerɛ nsonsonoe a ɛda texture ahorow ntam
5. Nwoma a wɔkyerɛw ne nhwehwɛmu– asase ani ayaresa ho kyerɛwtohɔ, Ra sɔhwɛ amanneɛbɔ, ahotew / pasivation kyerɛwtohɔ, ne ahwehwɛde ahorow wɔ nneɛma a wɔde kyekyere ne agyiraehyɛde ho

Sɛ wɔde eyinom ka ASTM gyinapɛn a ɛfata (sɛ nhwɛso no A269, A270) ne grade selection (te sɛ 304L anaa 316L) ho a, wobetumi akyerɛ dade a ɛnyɛ den a ɛyɛ pɛpɛɛpɛ nsukorade wɔ ɔkwan a wotumi yɛ, wotumi hwɛ mu, na wotumi hwehwɛ mu.
