Maelezo ya Bidhaa

Bomba la mabomba ya mraba na mstatili ni mabomba yaliyotolewa ambayo hutumika sana kwa aina zote za miradi ya utengenezaji ambapo upinzani mwepesi na kutu ni jambo la msingi. Bomba la mraba lina pembe za mraba ndani na nje, bila mshono wa kulehemu.

Mabomba ya mraba na mstatili ni vifaa vya ujenzi vinavyotumika kwa matumizi mbalimbali, vya kudumu, na vya gharama nafuu vinavyotumika katika ujenzi, viwanda, fanicha, na mapambo. Womic Steel hutoa aina mbalimbali za mirija ya mraba ya chuma katika ukubwa na unene mbalimbali.

Sehemu yenye mashimo ya mstatili/ mraba huundwa kutoka kwa koili na kisha hupitia mfululizo wa feri. Huunganishwa kutoka ndani ili kuunda umbo lao.

Bomba la Chuma la Mraba la ASTM A500 Lililowekwa Mabati Kabla (22)

Mchakato wa sehemu yenye mashimo (Mirija ya Mraba/Mstatili):
● Sehemu ya Mraba yenye Umbo la Baridi
● Sehemu ya Mstatili Yenye Umbo la Baridi
● Sehemu ya Mraba ya Kumalizia Moto
● Sehemu ya Mstatili yenye Pengo la Moto

Uainishaji wa Mchakato wa Uzalishaji wa Bomba la Chuma la Mraba
Kulingana na mchakato wa uzalishaji, bomba la mraba limegawanywa katika: bomba la mraba lililokunjwa kwa moto, bomba la mraba lililokunjwa kwa baridi, bomba la mraba lililotolewa bila kipimo, bomba la mraba lililounganishwa.

Bomba la mraba/mstatili lililounganishwa limegawanywa katika:
(a) kulingana na mchakato wa bomba la mraba lenye umbo la arc, bomba la mraba lenye umbo la upinzani (masafa ya juu, masafa ya chini), bomba la mraba lenye umbo la gesi, bomba la mraba lenye umbo la tanuru.
(b) kulingana na weld ya bomba la mraba lililounganishwa moja kwa moja, bomba la mraba lililounganishwa kwa ond.

Mchakato wa Uzalishaji

Udhibiti wa Ubora

Ukaguzi wa Malighafi, Uchambuzi wa Kemikali, Jaribio la Mitambo, Ukaguzi wa Kuona, Jaribio la Mvutano, Ukaguzi wa Vipimo, Jaribio la Kupinda, Jaribio la Kunyoosha, Jaribio la Athari, Jaribio la DWT, Jaribio la NDT, Jaribio la Maji Tuli, Jaribio la Ugumu…..

Kuweka alama, Kuchora kabla ya kuwasilisha.

Ufungashaji na Usafirishaji

Mbinu ya kufungasha mabomba ya chuma inahusisha kusafisha, kuweka makundi, kufungasha, kufungasha, kuweka lebo, kuweka kwenye godoro (ikiwa ni lazima), kuweka kwenye vyombo, kuweka kwenye vifungashio, kufunga, kusafirisha, na kufungua. Aina tofauti za mabomba ya chuma na vifaa vyenye mbinu tofauti za kufungasha. Mchakato huu kamili unahakikisha kwamba mabomba ya chuma yanasafirishwa na kufika mahali yanapoenda katika hali nzuri, tayari kwa matumizi yaliyokusudiwa.

Matumizi na Utumiaji

Mabomba ya chuma hutumika kama uti wa mgongo wa uhandisi wa kisasa wa viwanda na ujenzi, na kusaidia matumizi mbalimbali yanayochangia maendeleo ya jamii na uchumi duniani kote.

Mabomba na vifaa vya chuma ambavyo Womic Steel ilitengeneza vilitumika sana kwa ajili ya mafuta, gesi, mafuta na mabomba ya maji, pwani/pwani, miradi ya ujenzi wa bandari na ujenzi, uchimbaji, miradi ya ujenzi wa Chuma, urundikaji na madaraja, pia mirija ya chuma ya usahihi kwa ajili ya uzalishaji wa roli za kusafirishia, n.k.
