Poslamaýan polat turbasy - Poslamaýan polat turbasy barada gürleşiň
Poslamaýan polat turbalar gurluş we maksatlar üçin ulanylýan we tehniki hyzmat etmek zerurlygy az bolan poslama çydamly güýçli we çydamly materialdyr. Poslamaýan turbanyň diametri we üýtgeýşi, programmanyň talaplaryna we nähili ulanylmalydygyna baglylykda tapawutlanýar. Köp adamlar üçin turbalar we turbalar birmeňzeş, bu iki önümiň ulanylmagy bilen baglanyşykly belli bir derejede bulaşyklyga sebäp boldy . Iki önümiň hem tegelek ýa-da tegelek kesim bolandygy sebäpli, şol bir funksiýalary ýerine ýetirýändigi çak edilýär. Turbalardan tapawutlylykda turbalar inedördül we gönüburçly we tegelek görnüş ýaly köp görnüşde gelýär. Turbalar bilen turbalaryň arasyndaky esasy tapawutlaryň biri, olaryň ulanylyşydyr. Turbageçiriji, gurluş maksatly däl-de, gazlary we suwuklyklary herekete getirmek üçin ulanylýan transport mehanizmidir. Içki diametri (ID) bilen ölçelýär. Turbalar gurluş maksatly ulanylýar we daşarky diametri we diwaryň galyňlygy bilen ölçelýär.Koprak oka -
Seamless Mechanical Tube-Stainless steel pipe
Abbreviated ERW, this is a format that signals a specific welding process – actually two processes, spot and seam welding. This process involves several specific steps where the steel is unwound and trimmed, then passed through rollers to cold-form the steel into the proper shape (circular, square or rectangular).From here, the edges are forced together into a butt joint, then welded at a very high temperature to form a flash weld. Once the weld is tested, the tube passes through various sizing rolls to achieve the proper size, and then the length is cut. The materials used here will generally be available in both hot-rolled and cold-rolled formats.Koprak oka -
how are steel tubes made-Welded Steel Pipe-ERW Steel Pipe
The use of steel pipes was started by a Scottish inventor in 1815 connecting the tubes to convey gas for lights. In 1836, the United Kingdom had a patent for the production of seamless steel pipes by the extrusion method, but it was not until 1885 that the German Mannismann brothers invented the process of directly producing seamless pipes from bar steel. The Mannismann brothers first invented the second in 1885. The roll cross-rolling piercing machine, invented the periodic tube rolling machine in 1891, and in 1903, the Swiss R Stiefel (RCStiefel) invented the automatic tube rolling machine (also known as the head-type tube rolling machine). Later, continuous tube rolling appeared All kinds of extension machines, such as machine and pipe jacking machine, began to form the modern seamless steel pipe industry.Koprak oka -

Düşnüksiz turba-ERW polat turbanyň önümçilik usuly
Düşnüksiz turbanyň önümçilik usuly takmynan kesiş usulyna (Mennesmann usuly) we ekstruziýa usulyna bölünýär. Öňki usul, ilki bilen turbany pyçak bilen deşip, soň bolsa tegelek bilen uzatmakdyr. Bu usul çalt önümçilik tizligine eýedir, ýöne turbanyň boş işleýşini talap edýär we esasan uglerod polat we az erginli polat turbalary öndürmek üçin amatly. Iň soňky usul, turbany boş ýa-da deşiji maşyn bilen deşmek, soňra bolsa ekstruder bilen polat turba çykarmak. Bu usul, siňdiriş usulyndan has täsirli we ýokary güýçli garyndy polat turbalary öndürmek üçin amatlydyr. Düwürtmek usuly hem, ekstruziýa usuly hem ilki bilen turbany boş ýa-da ingot bilen gyzdyrmaly we öndürilen polat turba gyzgyn tok diýilýär. Gyzgyn iş usullary bilen öndürilen polat turbalar käwagt zerur bolanda sowuk bolup biler.Koprak oka -
Comparison of Hot Rolled & Cold Rolled SS Steel Pipe-ERW Steel Pipe
Hot rolled seamless steel pipe can damage the casting structure of the steel ingot, refine the crystal grains of the steel, and eliminate the defects of the microstructure. In this way, the steel organization is compacting and the mechanical properties would be improved.This improvement is reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.Koprak oka -
Poslamaýan polat turba-a500 erw polat turba turbalary zawodlary
Umumy bökdençsiz polat turbalaryň (smls turbanyň) önümçilik prosesi iki görnüşe bölünip bilner: sowuk we gyzgyn. Sowuk rulonly polat turbalaryň önümçilik prosesi, adatça gyzgyn rulondan has çylşyrymly. Ölçeg synagynda, üstki çatryklara jogap bermese, turbany kesiji maşyn bilen kesmeli we uzynlygy bir metre golaý boş ýere kesmeli. Soňra anneasiýa prosesine giriň. Düwürtigi kislotaly suwuklyk bilen duzlamaly. Duz alanyňyzda, üstünde gülgüne köpdügine üns beriň. Düwürtik köp bolsa, polat turbanyň hiliniň degişli standartlara laýyk gelmeýändigini aňladýar. Daş görnüşi boýunça, sowuk rulonly polat turbalar gyzgyn togalanýan polat turbalardan gysga. Sowuk rulonly polat turbalaryň diwar galyňlygy, adatça gyzgyn togalanýan polat turbalardan has kiçi, ýöne üstü galyň diwarly bökdençsiz polat turbalaryndan has ýagty görünýär. Gaty gödek, gaty köp gabyksyz.Koprak oka -
Kebşirlenen turba ýasamak prosesini öwrenmek - Kebşirlenen polat turba
Turbany ýasamak üçin adatça dört dürli kebşirleýiş prosesi ulanylýar. Bu kebşirlerde doldurgyç metal ýoklugy sebäpli, kebşiler iň bolmanda esasy metallar ýaly güýçlidir. Freokary ýygylyk (HF) kebşirlemek. Häzirki wagtda iň ýumşak polat we alýumin turbasy HF kebşirleýjiler bilen kebşirlenýär, bu turbalar bezeg maksatly bolsa 400 seriýaly poslamaýan we hatda 300 seriýaly üçin hem amatly. Satylan HF kebşirleýjileriniň takmynan 95 göterimi tranzistorlary ulanyp, gaty berkdir. üýtgeýän ýygylyk tokyny dörediň. Diametri 1/4 dýuýmdan az önümleri kebşirlemek we kebşirleýjiniň ýokary hatar tizliginde 300 poslamaýan polatdan basyş hilli kebşirlemek ukybyny giňeltmek üçin gözlegler geçirildi.Koprak oka -
Polat turbalary we turbalary öndürmegiň usullary-ERW polat turbasy
Billet-Heating-Mannesmann piercer-Elongator-Plug mill-Reeler-Reheating-SizerWhen a seamless pipe is made by rolling, the rolling method involves piercing the material while it is being rolled, and is suitable for mass production. The figure shows the manufacturing process used in the Mannesmann plug mill, which is a typical rolling process. The Mannesmann-type piercer reduces the material by rolls that are inclined obliquely to each other. When the round billet is rotated while being compressed in the diametric direction, the central part of the billet becomes loose, which makes it easy to pierce a hole through the center. This is called the Mannesmann effect. The pierced portion is expanded by the elongator, and the wall thickness is then thinned and elongated by the pug mill. The internal and external surfaces are smoothed by the reeler, and the final dimensional adjustments are made by the sizer.Koprak oka
