How to bend stainless steel tubes?
This multitude to exist sposobov. Choice dependent from the material, diameter and wall units tolschynы stainless pipes, Volume works, neobhodymoho availability of equipment. Pipes often prymenyayutsya stainless steel inductrial and individually in construction. Avto Sogn stainless steel pipe IZ, Need a Special Apply knowledge and navыky, will be about something rasskazano on. Famous Methods bending stainless pipes can be a partition on horyachye Cool, as well as on ruchnыe and mehanycheskye. It is important to know, something impossible stainless steel Pipes bend burning process (at nahrevanyy horelkoy) Therefore WILL BE opysanы Only Methods cold yzhyba. Bending tubes Typically, accompanied nezhelatelnыmy phenomenon, vlyyayuschymy on posleduyuschuyu operation. Ability s appearance as dependent material, diameter, way yzhyba.
Negative consequences bending:
• thinning of the outer wall units yzhyba
• Education and folds on the inner wall units yzlomov
• Changing forms lumen (ovalyzatsyya)
• Increase radius bending process yzhyba after the effect Due pruzhynyascheho
In yzhybe stainless pipes happening neravnomernoe Changing ee tsylyndrycheskoy forms and tolschynы stenok. As a result of voznykayuschyh at yzhybe tense happening metal thinning and thickening External inner stenok. In vыrazhennom utonchenyy outer parts yzhyba arise oslablenye pipes. This adverse vesma so vneshnyaya As yzhyba pipe wall units in bolshej degrees podverhaetsya dvyzhuschehosya pressure on nemu product. Else one crucial factor oslablyayuschym pipe after shybanyya, is the ovalyzatsyya ee. Especially preferably at uchytыvat This Piping, prednaznachennoho for transportyrovanyya product under pulsating load. When Using hnutыh ovalyzatsyya pipes in the construction, in addition, uhudshaet External view of Constructions. Therefore perform at yzhyba stremyatsya for mynymyzatsyy эtoho phenomenon. Under the action szhymayuschyh forces voznykayuschyh at yzhybe, the inner ego part obrazuyutsya thickening, and ryade cases - fold. These forms Changed lumen in pipelines uvelychyvayut Resistance Movement and the likelihood of corrosion product, and besides, pryvodyat for oslablenyyu pipes As nesuschey Constructions.
Methods predotvraschenyya ovalyzatsyy:
Basic Methods Cold bending predusmatryvayut Receptions, sohranyayuschye yshodnuyu form transverse cross-section blanks. There are two major preferred method Saving yshodnoy kruhloy forms: podderzhyvanye wall units from the inside - inner Peak limiter and SHIFT bokovыh stenok pipes in the direction Expansion - External limiter. AS A limiter can be vnutrenneho Apply kalybruyuschuyu stopper (Dorn) Or Various napolnytely. Napolnytelyamy mogut bыt Rubber lehkoplavkye metals, smolы Or water. Zhestkye napolnytely More nadezhnыe give results in terms of lumen Saving forms, Therefore îíè More rasprostranenы. However napolnyteley Using elastic observed menshee Stretch outer sides yzhyba. For luchsheho Saving forms transverse cross-section and Production More accurate Apply simultaneously recommend the External and inner dependence ohranychytely.
