3. Ukuvuza komphezulu wokutywina

Isizathu:

(1) Ukutywina umphezulu wokugaya ngokungalinganiyo, akunakudala umgca osondeleyo;

(2) Umbindi ophezulu wonxibelelwano phakathi kwesiqu sevalvu kunye nenxalenye yokuvala uxhonyiwe, okanye unxityiwe;

(3) Isiqu sevalvu sigobile okanye asihlanganiswanga kakuhle, ukuze iindawo zokuvala zigobe okanye zingabikho kwindawo yazo;

(4) Ukukhetha okungafanelekanga komgangatho wezinto zomphezulu wokutywina okanye ukukhetha ivalvu ngokweemeko zokusebenza.

Indlela yokulungisa:

(1) Khetha izinto kunye nohlobo lwe-gasket ngokuchanekileyo ngokweemeko zokusebenza;

(2) Ukulungiswa ngononophelo, ukusebenza kakuhle;

(3) Ibholithi kufuneka iqiniswe ngokulinganayo nangokulinganayo, kwaye isikrufu se-torque kufuneka sisetyenziswe ukuba kuyimfuneko. Amandla okuqinisa kwangaphambili kufuneka ahlangabezane neemfuno kwaye akufuneki abe makhulu kakhulu okanye mancinci. Uqhagamshelo lweflange kunye nomsonto kufuneka lube nomsantsa othile wokuqinisa kwangaphambili;

(4) Indibano yeGasket kufuneka ihlangabezane namandla afanelekileyo, afanayo, iGasket ayivumelekanga ukuba ijikeleze kwaye isebenzise iGasket ephindwe kabini;

(5) Ukugqwala komphezulu wokutywina okungashukumiyo, ukucubungula umonakalo, umgangatho wokusetyenzwa awuphezulu, kufuneka kulungiswe, kugaywe, kuhlolwe imibala, ukuze umphezulu wokutywina ongashukumiyo uhlangabezane neemfuno ezifanelekileyo;

(6) Ukufakelwa kwe-gasket kufuneka kuqwalaselwe ukuba umphezulu ococekileyo, otywiniweyo kufuneka ube ne-parafini ecacileyo, i-gasket mayingawi.

4. Ukuvuza kwindawo yokudibanisa iringi yokutywina

Isizathu:

(1) Indandatho yokutywina ayisongwanga kakuhle

(2) Umgangatho wokutywina iringi kunye nokuwelda komzimba, umgangatho wokuwelda ongaphezulu awulunganga;

(3) Umsonto woqhagamshelo lwendandatho yokutywina, isikrufu, iringi yoxinzelelo ikhululekile;

(4) Indandatho yokutywina iqhagamshelwe kwaye igqwalile.

Indlela yokulungisa:

(1) Ukuvuza kwindawo yokutywina kufuneka kuzaliswe ngeglue uze emva koko kugoqwe kuze kulungiswe;

(2) Indandatho yokutywina kufuneka ilungiswe ngokwemigaqo yokuwelda. Ukuba indawo yokutywina ayinakulungiswa, umphezulu wokuqala kunye nokucutshungulwa kwawo kufuneka kususwe;

(3) Susa isikrufu, ucoce iringi yoxinzelelo, utshintshe iindawo ezonakeleyo, ucofe umphezulu osondeleyo wesitulo sokutywina kunye nokudibanisa, uze uphinde udibanise. Iindawo ezonakeleyo ngenxa yokugqwala zingalungiswa ngokuwelda, ukubopha, njl.njl.

(4) Umphezulu woqhagamshelo lwendandatho yokutywina ugqwalile, onokulungiswa ngokusila, ukubopha, njl.njl., kwaye indandatho yokutywina kufuneka itshintshwe xa ingenakulungiseka.

5. Ukuvuza komzimba wevalvu kunye nesigqubuthelo sevalvu:

Isizathu:

(1) Umgangatho wokuphosa intsimbi ephosiweyo awuphezulu, umzimba wevalvu kunye nomzimba wesiciko sevalvu unemingxuma yesanti, ulungelelwaniso olukhululekileyo, ukufakwa kweslag kunye nezinye iziphene;

(2) Iqhekezo elibandayo;

(3) Ukuwelda okungekho semgangathweni, kukho ukufakwa kwe-slag, ukungawelda, iintanda zoxinzelelo kunye nezinye iziphene;

(4) Ivalvu yentsimbi ephosweyo yonakele emva kokubethwa zizinto ezinzima.

Indlela yokulungisa:

(1) Phucula umgangatho wokubumba, kwaye wenze uvavanyo lwamandla ngokungqongqo ngokwemigaqo ngaphambi kokufakwa;

(2) Kwiivalvu ezinamaqondo obushushu angaphantsi kwe-0° kunye ne-0°, kufuneka kugcinwe okanye kuxutywe ubushushu, kwaye amanzi kufuneka angabandakanywa kwiivalvu eziyekiweyo ukusetyenziswa;

(3) Ukuwelda komzimba wevalvu kunye nesigqubuthelo sevalvu esenziwe ngokuwelda kufuneka kwenziwe ngokweenkqubo ezifanelekileyo zokusebenza kokuwelda, kwaye ukufunyanwa kweziphene kunye novavanyo lwamandla kufuneka kwenziwe emva kokuwelda;

(4) Akuvumelekanga ukutyhala izinto ezinzima kwivalvu, kwaye akuvumelekanga ukubetha iivalvu zentsimbi ephosiweyo kunye nezingeyontsimbi ngesando sesandla.
