Forbhreathnú
Coinneoimid feabhas agus foirfeacht ar ár gcuid earraí agus seirbhísí. Ag an am céanna, déanaimid an obair go gníomhach chun taighde agus feabhsú a dhéanamh ar Píob Cruach Mheicniúil, Le leas a bhaint as bainistíocht tionscail, tá an gnó i gcónaí tiomanta do thacaíocht a thabhairt d'ionchais a bheith ina cheannaire margaidh reatha ina dtionscail faoi seach. Tá an chaitheamh i gcónaí bunúsach dár misean. Táimid i gcónaí ag teacht le freastal ar chustaiméirí, ag cruthú cuspóirí bainistíochta luacha agus ag cloí leis an smaoineamh sincerity, dúthracht, bainistíochta leanúnach.
Iarratas
Úsáidtear go príomha é le haghaidh meicniúil agus úsáidtear é chun sorcóirí gáis a dhéanamh. áiríonn sé feadánra meicniúil gan uaim cruach carbóin agus cóimhiotail, agus clúdaíonn sé feadánra meicniúil te-chríochnaithe gan uaim agus feadánra meicniúla fuarchríochnaithe i méideanna suas go dtí agus lena n-áirítear 12 3⁄4 in. (323.8 mm) trastomhas lasmuigh le haghaidh feadáin chruinn le tiús bhalla mar is gá.

A Ní fhéadfaidh lamháltais tiús balla a bheith infheidhme maidir le ballaí 0.199 isteach (5.05 mm) agus níos lú; téigh i gcomhairle leis an monaróir maidir le lamháltais balla ar mhéideanna feadáin den sórt sin.
gné níos tábhachtaí, ansin ba chóir feadánra fuar-oibrithe a shonrú go dtí trastomhas taobh istigh agus tiús bhalla nó trastomhas lasmuigh agus trastomhas taobh istigh.
Feadánra Meicniúil Garbh-Chompaite — Ní sháróidh an t-athrú ar thrastomhas lasmuigh agus tiús balla an lamháltas sa Tábla. Clúdaíonn an tábla lamháltais mar a chuirtear i bhfeidhm ar thrastomhas lasmuigh agus tiús bhalla agus baineann sé leis an méid sonraithe.
Feadánra Meicniúla Thalmhaithe—Ní rachaidh athrú ar thrastomhas lasmuigh thar na lamháltais sa Tábla. De ghnáth déantar an táirge seo ó fheadán fuar-oibrithe.
Faid - Cuirtear feadáin mheicniúla ar fáil go coitianta i muilinn, 5 troigh (1.5 m) agus os a chionn. Cuirtear faid gearrtha cinnte ar fáil nuair a shonraíonn an ceannaitheoir é. Taispeántar lamháltais faid i dTábla .
Díreach — Ní sháróidh na lamháltais dhíreacha le haghaidh feadánra cruinn gan uaim na méideanna a thaispeántar sa Tábla.
Ceanglas Tástála
Tástáil 1.Hardness
Nuair is gá teorainneacha cruas, rachfar i gcomhairle leis an monaróir. Liostaítear cruasanna tipiciúla i dTábla . Nuair a shonraítear é, déanfar an tástáil cruas ar 1 % de na feadáin.
Tástálacha 2.Tension
Nuair is gá airíonna teanntachta, rachfar i gcomhairle leis an monaróir. Tá airíonna teanntachta tipiciúla do chuid de na gráid is coitianta agus na coinníollacha teirmeacha liostaithe sa tábla.
Tástálacha 3.Nondestructive
Tá cineálacha éagsúla tástálacha ultrasonaic nó leictreamaighnéadacha nondestructive ar fáil. Déanfar an tástáil a úsáidfear agus na teorainneacha iniúchta a bhunú le comhaontú an mhonaróra agus an cheannaitheora.
Tástáil 4.Flaring
Nuair a bhíonn ceanglais speisialta ann maidir le glaineacht cruach, déanfar na modhanna tástála agus na teorainneacha glactha a bhunú le comhaontú an mhonaróra agus an cheannaitheora.
