Taw qhia rau DI Pipe Jointing Systems

Electrosteel D]. Cov kav dej thiab Fittings muaj nrog cov nram qab no hom kev sib koom ua ke:

- Lub qhov (socket & Spigot) Slexible Push-on Joints
- Restrained Joints Push-on Hom
- Mechanical Flexible Joints (tsuas yog fittings)
- Flanged Joint

Socket & Spigot Yooj Yim Push-on Joints

Socket thiab Spigot Flexible Joints yog sib sau ua ke nrog hluavtaws (EPDM / SBR) roj hmab gaskets ntawm cov duab tshwj xeeb. Lub gasket muaj ib qho nyuaj 'Heel' thiab mos 'bulb'. Hauv Push-on sib koom lub qhov muag muag ntawm cov roj hmab gasket yog compressed thaum lub spigot muab tso rau hauv lub qhov (socket). Lub 'Heel' locks txoj hauj lwm ntawm lub gasket thiab tsis tso cai rau lub gasket tsiv tawm thaum lub spigot raug thawb rau hauv. Qhov sib koom ua ke yuav nruj dua nrog kev nce hauv cov dej hauv siab. Cov roj hmab yog nyob rau hauv ib qho chaw thiab tsis tuaj yeem tshuab tawm.

Permissible Deflection ntawm qhov (socket) thiab Spigot Joints

Qhov twg nws yog qhov tsim nyog los deflect lub raj xa dej los ntawm txoj kab ncaj nraim, nyob rau hauv txoj kab ntsug lossis kab rov tav, kom tsis txhob muaj kev cuam tshuam thiab lwm yam, deflection ntawm kev sib koom ua ke yuav tsum tsis txhob tshaj cov hauv qab no:

Electrosteel Ductile Iron Pipe ioints yog hom kuaj

Electrosteel tus tsim ntawm lub qhov (socket) thiab cov roj hmab gasket ua kom muaj kev ruaj ntseg sib koom ua ke los ntawm Hom Kev Ntsuas raws li BSEN: 545 thiab ISO: 2531 . Hom Kev Xeemyog kuaj cov yeeb nkab thiab cov yeeb nkab sib koom ua ke ntawm kev ua haujlwm hnyav (cov khoomthiab siv) kom ntseeg tau tias kev ua tau zoo txaus siab rau lub sijhawm ntev.

Cov kev pom zoo Hom Kev Xeem raws li BS EN: 545/598, ISO: 2531 yog:

1. Leak Tightness ntawm pob qij txha mus rau qhov zoo, tsis zoo thiab dynamic sab hauvSiab.
2. Tightness ntawm cov pob qij txha mus rau qhov zoo sab nraud siab.
3. Leak nruj thiab Mechanical Resistance ntawm Flanged Joints.
4. Kev kuaj rau kev puas tsuaj.
5. Kev ntsuas tshuaj tiv thaiv rau cov kua dej.

Lub koom haum British Standard Institute (BSI) tau saib xyuas hom kev xeem thiab raws licov 'KITEMARK' Daim ntawv tso cai tau raug tso tawm.
