Porogaramu nyamukuru

1. Ishingiro ry'inkuta zo munsi y'ubutaka:Imisingi miremire y'inyubako ndende, inganda, ububiko, inyubako z'ubucuruzi n'iz'abaturage. Imisingi y'ibirundo (ikwiriye ubwoko bwose bw'inyubako).

2. Ishingiro ry'ibirundo by'ibiraro:Imisingi itwara imizigo ku biraro by'imihanda minini, ibiraro bya gari ya moshi, n'inzira zo mu mijyi. Imisingi ikoreshwa ku biraro by'imigezi, ibiyaga, n'inyanja.

3. Kubaka icyambu:Ishingiro ryikoresho ritwara imizigo ku byambu, aho amato akorera, n'aho bashyira imizigo. Ibikoresho biremereye n'ibikoresho byo gutwara imizigo ku byambu.

4. Imishinga y'Ingufu z'Umuyaga n'Ubwubatsi bw'Amato mu Nyanja:Ishingiro ry'ibyuma by'umuyaga byo mu nyanja. Igishushanyo mbonera gishyigikira urubuga rwo mu nyanja, imiyoboro y'amazi yo mu nyanja, inkuta z'inyanja, nibindi. Kurwanya amazi yo mu nyanja, kurwanya amazi yo mu nyanja, no kurwanya ingese zo mu nyanja.

5. Ubwubatsi Bunini bw'Ibwubatsi:Imisingi miremire ifite imiringoti minini y'umurambararo w'imishinga minini y'ubwubatsi (nk'ingomero, sitasiyo zo munsi y'ubutaka, n'imiyoboro y'amazi). Inkunga ku mashini n'imitwaro y'inganda.

Gupakira no Gutanga

1. Gupfunyika:Imishumi y'icyuma kugira ngo yoroshye kuyifata.
Ibiti cyangwa uduce tw’ibiti bishyirwa hagati y’ibirundo kugira ngo hirindwe kwangirika mu gihe cyo kubitwara.
Kurinda ubuso (ni ngombwa): Irangi ry'umukara, amavuta yo kwirinda ingese, cyangwa imizingo ya pulasitiki.
Ibirundo bya galvani bishyushye bishobora kugira agapira k'agateganyo gakingira kugira ngo hirindwe gushwanyagurika ku buso.
Gupfunyika byihariye biraboneka iyo ubisabye.

2. Gutanga:Uburebure busanzwe bw'ibicuruzwa: metero 6 na metero 12. Uburebure bwihariye burahari kugira ngo buhuze n'ibyo umushinga wawe ukeneye.
Bikwiriye gutwara abantu mu mazi, gari ya moshi, cyangwa mu muhanda.
Igihe cyo gutanga ubusanzwe ni iminsi 15-30 nyuma yo kwemeza kwishyura, bitewe n'ingano n'ibipimo.
Bikwiriye koherezwa mu mahanga ku isi yose, hamwe n'inyandiko zuzuye (icyemezo cy'igenzura, urutonde rw'ibipakiye, inyemezabwishyu y'imizigo).

3. Gufata ingamba zo kwirinda:Koresha crane cyangwa forklift ifite imigozi cyangwa imigozi kugira ngo wirinde kwangirika kw'imiyoboro.
Bika ahantu hakonje, humutse kandi hari umwuka mwiza kugira ngo hirindwe ingese mbere yo kuyishyiraho.
Ku bicuruzwa binini cyane/birengeje urugero, nyamuneka kurikiza amabwiriza yo kohereza ibicuruzwa mu gace utuyemo.

Ibibazo Bikunze Kubazwa

1. Ni ikiImiyoboro y'icyuma ya ASTM A252 yo mu cyiciro cya 3?
Imiyoboro y'icyuma ya ASTM A252 yo mu rwego rwa 3 ni imiyoboro y'icyuma ishongeshejwe kugira ngo ikoreshwe nk'inkingi y'urufatiro rwimbitse munsi y'inyubako, ibiraro, ibyambu, n'ubwubatsi bwo mu nyanja. Hari inzira ebyiri zo gusudira kuri iyi miyoboro: umuyoboro wo gusudira wa arc ushongeshejwe na helical (SSAW) cyangwa umuyoboro wo gusudira wa arc ushongeshejwe na longitudinal (LSAW/EFW).

2. Ni ingano n'uburebure ki biboneka?
Umurambararo wo hanze: 219 mm - 3000 mm (XXL/ingano nini y'umurambararo irahari) Ubunini bw'urukuta: 6-40 mm. Uburebure busanzwe bw'ibikoresho ni metero 6 na metero 12, kandi uburebure bwihariye burashobora gutangwa iyo ubisabye.

3. Ni ibihe bipimo ngenderwaho by'ibikoresho n'imiterere ya mekanike?
Ibikoresho Bisanzwe: ASTM A252 Icyiciro cya 3
Ingufu z'umusaruro: ≥345 MPa
Ingufu zo gukurura: 455~620 MPa
Uburebure: ≥20%%

4. Ese nshobora kubona icyemezo cy'ubuziranenge n'igenzura?
Yego, imiyoboro yose y'ibyuma ifite icyemezo cya ISO 9001. Inyandiko zose zisabwa harimo na raporo z'abandi ziturutse kuri SGS, BV cyangwa urundi rwego rwemewe.

5. Imiyoboro y'ibyuma ipakiye gute?
Ipfunyika imiyoboro y'icyuma ikoresheje igitambaro cy'icyuma hanyuma ikagishyira mu mwanya wacyo nta cyangiritse. Gupfunyika/gupfunyika cyangwa/n'ibindi byavuzwe haruguru birasabwa hakurikijwe uburyo bwo kohereza. Hari ipaki yihariye.

6. Igihe cyo gutanga ni ikihe?
Igihe cyo kohereza: Iminsi 15-30 nyuma yo kwemeza ibyo watumije (biterwa n'ingano, imiterere n'aho ugana).

7. Ese birashoboka guhindura ingano?
Yego, umurambararo n'ubugari bw'urukuta bishobora guhindurwa hakurikijwe ibisabwa n'abakiriya.
