He aha ka valve whola?

Nā pale (ʻO ka wai kānāwai'ōlelo aʻo) Ua hoʻokomoʻia ka hōʻoia i ka United Kingdom In 1998.

Ua hoʻokumuʻia e hōʻoia i nā huahana (Valves / Pipes / Fitting…) Hoʻohana i nā'ōnaehana lako wai, pono e hoʻokō i nā kūlana i hoʻonohonohoʻia e ka wai wai (Waiwai wai) Ruiail 1999 a me ka wai wai scottish. Ua hoʻokeleʻia ka hana i ka hana o ka wai, kahi hui i loko o kaʻoihana wai i ka UK.

Pehea e hōʻoia ai i kahi palapala hōʻoia Valve?

'Lelo 1: Komo i ka papa kuhikuhi i ka papa kuhikuhi pūnaewele

• E kipa i ka pūnaewele o ka pahu: E helewww.wrasapprovals.co.uk
• E hoʻokele i ka “Nā papa kuhikuhi”: Poloka “Nā papa kuhikuhi” mai ka papa kuhikuhi.
• Eʻimi no ka palapala hōʻoia:
  • Kūlana 1: E komo i kaHoʻopili i nā helu palapala (E.g., 2309345) I ka huliʻana.
  • Kūlana 2: Huli eKAHIKHAN HELANA MAKAU(E.g., ningbo Westhway m&E CO., Ltd.), 'ʻano'iohi, OoleHua'ōlelo Inā loaʻaʻole ka helu palapala.

'Lelo 2: E nānā i nā kiko'ī palapala

Loaʻaʻoe i ka palapala hōʻoia ma ka papa kuhikuhi, E hōʻoia i nā kiko'ī aʻe:

1. Helu helu palapala: E hōʻoia e pili ana i ka helu i hāʻawiʻia i ka helu i hāʻawiʻia ma keʻano pilikino / Digital.
2. KAHIKHAN HELANA MAKAU: E hōʻoia i ka papa inoa inoa inoa inoaʻo ia ka mea hana a iʻole ka mea kūʻai aku o ka huahana.
3. ʻO ka wehewehe piha: E nānā inā he inoa o ka huahana / Model a me ka mea āu e hōʻoia ai i ka mea āu e hōʻoia nei.
4. Nā lā kūpono: Pono nā palapala hōʻoia5 makahiki. E hōʻoia i ka “Kūpono mai” a “Ka lā pau” i kēia manawa.
5. ʻAeʻaeʻia: E hōʻoia inā heʻO kaʻaeʻia ka huahana OoleApono (nā mea non-metallic).

'Lelo 3: Cross-Check with the Issuing Laboratory

• WRAS certificates are issued byUKAS-accredited laboratories (E.g., WRc-NSF, BOTEST). Contact the lab directly if doubts arise:
  • Email the lab: Provide the certificate number and request confirmation (e.g.,info@wrcnsf.com for WRc-NSF).
  • Verify lab credentials: Ensure the lab is listed on the UKAS website (www.ukas.com).

'Lelo 4: Inspect the Physical/Digital Certificate

• Check security features:
  • Holographic seal: Genuine certificates include a WRAS hologram.
  • QR code: Scan the QR code (if present) to redirect to the official WRAS directory entry.
  • Authorized signatures: Ensure the WRAS approvals manager signs the certificate.
• Look for inconsistencies:
  • Misspellings, blurry logos, or incorrect UKAS accreditation numbers.

He aha nā mea e hoʻopiliʻia ai nā mea kanu i hoʻopaʻaʻia?

1. Material Safety
   • Nickel-plated brass construction to prevent leaching of lead and other harmful substances, ka hopena me ka inuʻana i nā kūlana palekana wai (E.g., Bs 6920, NSF / ASI 61).
2. Nā helu kaomi
   • Nā'āpana likeʻole e pili ana i nā helu paʻakikī, E.g., Pn16 i pn40 (E.g., Pn40 no 1/4 "-1", Pn25 no 21/2 "-3").
3. Lumi mahalaha
   • Ka hanaʻana i ka hanaʻana mai0° C i 120 ° C, me nā kūlana hana kūikawā ma lalo o nā kūlana kiʻekiʻe (E.g., ≤0.15 m³ / h leakage ma 650 ° C no 30 mau minuke i nā papa hana ahi).
4. Hoʻolālā hoʻolālā
   • Hoʻolālā piha piha (ho'ēmiʻia ka uahi), anti-busout stem (pale i nā mea hoʻopihapiha), a hoʻonuiʻia i nā mīkini hōʻailona (E.g., Hoʻoponopono i nā lāʻau Gland, Nā'Āpana PTF).
5. Nā hiʻohiʻona noi
   • Nā kūlana likeʻole nohau paha. nā noiʻoleʻole (E.g., 5 Bar no ke kinoea, 25 Bar no ka hau ole). ʻO nāʻano hana kūikawā no ka hoʻohanaʻana / hoʻohanaʻoihana (E.g., Nā Kūlana PTFE-Lined no nā Pūnaewele Corrosive).
6. Nā hoʻokolokolo hoʻokolokolo
   • ʻO ka hōʻoiaʻana i ka mana ikaika (I 331 No ka paʻaʻana), ʻO ka ho'āʻoʻana o nā mea hanaʻole (Bs 6920), a me ke ahi kaua (E.g., ATEX / CPR COMPLEANES).

No ke aha ke kumu kūʻai nui?

ʻO ka hoʻopiliʻana i ka hōʻoia no ka hāʻawiʻana i nā'ōnaehana wai wai ma UK.

Ke koi nei ke kino o ke kino o ke kino i nā meaʻai kiʻekiʻe a me nā lako. Nā Vilves, pipes, a me nā fitters pono e hoʻopiliʻia no ka palekana a me ka hana.

ʻO Bmag ka hōʻoia no nā Valves

Nui nā huahana Vmag a Bmag ua loaʻa iā lākou ka hōʻoia, me ka:

• Nā mea i hoʻopiliʻia
• Nā mea iʻaeʻia iʻaeʻia
• Nā pale kaulike kaulike iʻaeʻia
• ʻO nā kākā iʻaeʻia nā balled balle
• Nā mea iʻaeʻia iʻaeʻia
• Nā'āpana iʻaeʻia i nā kumulāʻau
• Nā mea i hoʻopiliʻiaʻo Y-Statiners

Hōʻike kēia i ka ikaika o nā mea hana a Bmag a me nā huahana huahana, Ke hana nei iā mākou i kahi hoa hana hilinaʻi no ka hui pūʻana.Kāhea iā mākou no kahi'ōlelo.
