Introduction to DI Pipe Jointing Systems

Electrosteel D]. Loaʻa nā paipu a me nā pono me nā ʻano o nā ʻōnaehana hoʻohui:

- ʻO nā hui hoʻokuʻu ma luna o ka Socket & Spigot
– ʻAno Push-on Nā ʻĀpana Kāohi
- Nā Hui Hoʻohui Mechanical Flexible (nā mea pono wale nō)
- Hui Flanged

Nā Hui Push-on hiki ke ma'alahi ka Socket & Spigot

Hoʻohui ʻia ʻo Socket a me Spigot Flexible Joints me synthetic (EPDM/SBR) rubber gaskets o ke ʻano kūikawā. He 'kuʻekuʻe' paʻakikī a me ka 'Bulb' palupalu. Ma ka hui Push-on, hoʻokomo ʻia ka puʻupuʻu palupalu o ka ʻōpala i ka wā e hoʻokomo ʻia ai ka spigot i loko o ke kumu. Hoʻopaʻa ka 'Heel' i ke kūlana o ka pahu a ʻaʻole e ʻae i ka hoʻoneʻe ʻana i ka pahu i ka wā e hoʻokomo ʻia ai ka spigot. Paʻa ka lāʻau i kahi wahi a ʻaʻole hiki ke puhi.

ʻAe ʻia ʻo Deflection ma ke Socket and Spigot Joints

Ma kahi e pono ai ke hoolele i ka paipu mai kahi laina pololei, ma ke kupapau a i ole ma ka mokulele paha, i mea e pale aku ai i na mea keakea a pela aku, aole e oi aku ka deflection ma ka hui i keia:

Hoʻāʻo ʻia nā ioints Electrosteel Ductile Iron Pipe

ʻO ka hoʻolālā ʻana o Electrosteel i ke kumu a me ka ʻili kino e hōʻoiaʻiʻo ʻia i ka leak-tight joint ma o Type Test e like me BSEN:545 a me ISO:2531. ʻAno hoʻāʻoke ho'āʻo nei i ka paipu a me ka paipu hui ma nā kūlana hana loa (ka huahanaa hoʻohana) e hōʻoia i ka hana ʻoluʻolu no ka manawa lōʻihi.

ʻO nā ʻano hoʻāʻo ʻia e like me BS EN:545/598, ISO:2531 ʻo ia:

1. Leak Tightness o na hono i Positive, Negative and Dynamic InternalPaʻi.
2. Leak Tightness of Joints to Positive External Pressure.
3. Leak tightness a me ka Mechanical Resistance o Flanged Joints.
4. Ho'āʻo no ka Abrasion Resistance.
5. Ho'āʻo no ke kūʻē ʻana i nā mea hoʻoheheʻe.

Ua nānā ka British Standard Institute (BSI) i nā ʻano hoʻāʻo a pēlāua hoʻopuka ʻia nā laikini 'KITEMARK'.
