Maelezo ya bidhaa
Mirija ya mabomba ya mraba na ya mstatili ni mabomba yaliyotolewa nje ambayo hutumiwa sana kwa aina zote za miradi ya uundaji ambapo uzani mwepesi na upinzani wa kutu ni jambo la msingi.Bomba la mraba lina pembe za mraba ndani na nje, bila mshono wa weld.
Mirija ya mabomba ya mraba na ya mstatili ni vifaa vingi vya ujenzi, vinavyodumu, na vya gharama nafuu vinavyotumika katika ujenzi, viwandani, samani na matumizi ya mapambo.Womic Steel hutoa anuwai ya mirija ya mraba ya chuma katika saizi na unene tofauti.
Sehemu ya mashimo ya mstatili/mraba huundwa kutoka kwenye koili na kisha kupita kwa mfululizo wa kiza.Wao ni svetsade kutoka ndani ili kuunda sura yao.
Mchakato wa sehemu ya mashimo (mirija ya Mraba/Mstatili):
● Sehemu ya Mashimo ya Mraba Iliyoundwa Baridi
● Sehemu ya Mashimo ya Mstatili Iliyoundwa na Baridi
● Sehemu ya Hollow Finish Square Hollow
● Moto Maliza Sehemu ya Mashimo ya Mstatili
Uainishaji wa Mchakato wa Uzalishaji wa Bomba la Chuma la Mraba
Kulingana na mchakato wa uzalishaji, bomba la mraba limegawanywa katika: bomba la mraba la moto lililovingirishwa, bomba la mraba lisilo na mshono, bomba la mraba lililoshonwa bila kipimo, bomba la mraba lenye svetsade.
Bomba la svetsade la mraba / mstatili limegawanywa katika:
(a) kulingana na mchakato wa arc svetsade bomba mraba, upinzani svetsade bomba mraba (high frequency, chini frequency), gesi svetsade bomba mraba, tanuru svetsade bomba mraba.
(B) kulingana na weld ya bomba moja kwa moja svetsade mraba, ond svetsade bomba mraba.

Ufungashaji & Usafirishaji
Njia ya ufungashaji wa mabomba ya chuma inahusisha kusafisha, kuweka kambi, kufunga, kuunganisha, kuweka lebo, kuweka pallet (ikiwa ni lazima), uwekaji wa vyombo, kuweka, kuziba, usafirishaji na upakiaji.Aina tofauti za mabomba ya chuma na fittings na njia tofauti za kufunga.Mchakato huu wa kina huhakikisha kwamba mabomba ya chuma yanasafirishwa na kufika mahali yanakoenda katika hali bora, tayari kwa matumizi yaliyokusudiwa.
Matumizi & Maombi
Mabomba ya chuma yanatumika kama uti wa mgongo wa uhandisi wa kisasa wa viwanda na kiraia, kusaidia safu nyingi za matumizi ambayo huchangia maendeleo ya jamii na uchumi ulimwenguni kote.
Mabomba ya chuma na viambatisho sisi Womic Steel zinazozalishwa kwa wingi kwa mafuta ya petroli, gesi, mafuta na bomba la maji, pwani / pwani, miradi ya ujenzi wa bandari ya bahari na jengo, uchimbaji, Chuma cha miundo, miradi ya ujenzi wa kurundika na madaraja, pia mirija ya chuma iliyosahihi kwa roller ya kusafirisha. uzalishaji, nk...
