Ukuthengiswa okuqondile kwefekthri kwamashubhu esikwele se-garbon squetic
Amashubhu akwe-Square ligama lamashubhu esikwele namashubhu axande, okungukuthi, amashubhu wensimbi ane-liqual and elingalingani uhlangothi olungalingani. Zenziwa ngokugoqa insimbi ye-strip ngemuva kokucutshungulwa. Ngokuvamile, insimbi ye-strip ayivuthiwe, ithambekele, igobile, futhi ifakwe i-welded ukwakha ishubhu eliyindilinga, bese iginyeka ibe yi-skwele ye-tube bese uthathe ubude obudingekayo.

Isingeniso Somkhiqizo
Eyaziwa nangokuthi yinsimbi yesikwele ne-unxande ebandayo, okubhekiselwa kuwo njengamashubhu esikwele namashubhu axande, ngamakhodi f no-j no-j no-j kanye ne-j ngokulandelana
1. Ukuphambuka okuvumelekile kodonga lweshubhu yesikwele ngeke kudlule ukuhlanganisa noma ukunciphisa u-10% wodonga odongeni lapho ubukhulu bodonga bungabi ngaphezu kwe-10mm, futhi noma u-8% wobukhulu bodonga lapho udonga mkhulu kune-10mm, ngaphandle kokuqina kodonga kwamakhona nezindawo zamandla.
2. Ubude obujwayelekile bokulethwa kwe-Square Tube ngu-4000mm-12000mm, nge-6000mm ne-12000mm evame kakhulu. Amashubhu akwe-Square avunyelwe ukulethwa ngobude obufushane nobude obungahleliwe abangaphansi kuka-2000mm. Zingalethwa futhi ngesimo samashubhu ezibonakalayo, kepha amashubhu abonakalayo kufanele anqunywe lapho esetshenziswa ngumthengi. Isisindo sobude obufushane nemikhiqizo emide engalungisiwe ngeke yedlule i-5% yevolumu yokulethwa ngokuphelele. Kumashubhu esikwele ngesisindo sethiyori enkulu kune-20kg / m, ngeke kwedlule i-10% yevolumu yokulethwa ngokuphelele.
I-3. I-curvature yeshubhu yesikwele ngeke yedlule i-2mm ngemitha ngayinye, futhi i-curvature ephelele ngeke idlule ku-0.2% wobude obuphelele
