    國(guó)內(nèi)目前大多使用的是矩形無(wú)縫鋼管及圓形無(wú)縫鋼管。相較于前兩種無(wú)縫鋼管,橢圓形無(wú)縫鋼管有漏風(fēng)率低,結(jié)構(gòu)強(qiáng)度高,剛性好,占用空間高度小等優(yōu)點(diǎn),橢圓形無(wú)縫鋼管的使用也逐漸增加。橢圓形無(wú)縫鋼管的制作,是經(jīng)過(guò)橢圓無(wú)縫鋼管機(jī)擴(kuò)張成型至客戶所需的橢圓無(wú)縫鋼管的標(biāo)準(zhǔn)尺寸,具有成型好,效率高,操作簡(jiǎn)便等優(yōu)點(diǎn),是通無(wú)縫鋼管道生產(chǎn)中不可缺少的設(shè)備。螺旋無(wú)縫鋼管換成橢圓無(wú)縫鋼管前工序之用· 【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】

    原理是:先將圓無(wú)縫鋼管逐步壓成橢圓形,然后進(jìn)入橢圓無(wú)縫鋼管機(jī),擴(kuò)張成型。橢圓無(wú)縫鋼管成型能滿足大多數(shù)冷拔無(wú)縫鋼管加工生產(chǎn)的要求,加工長(zhǎng)度為3米,橢圓冷拔無(wú)縫鋼管除外形美觀優(yōu)點(diǎn)外、強(qiáng)度更高氣密性更好且大大降低無(wú)縫鋼管安裝空間(高度)擴(kuò)展了橢圓無(wú)縫鋼管應(yīng)用范圍,【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】代替目前矩形無(wú)縫鋼管的產(chǎn)品。橢圓無(wú)縫鋼管自投放市場(chǎng)以來(lái),因其本身具有卓越性能及低廉的成本,在通風(fēng)、空調(diào)系統(tǒng)中的應(yīng)用不斷得到推廣,目前大部分產(chǎn)品也廣泛應(yīng)用于造船、通風(fēng)、凈化、紡織、會(huì)展、隧道等通風(fēng)除塵領(lǐng)域。【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】
    排水用大口徑螺旋鋼管焊縫呈螺旋線分布,焊縫長(zhǎng),尤其是處于動(dòng)態(tài)條件下焊接時(shí),焊縫還來(lái)不及冷卻就離開(kāi)了成型點(diǎn),極易產(chǎn)生焊接熱裂紋。裂紋的方向和焊縫平行,和鋼管軸線成一定夾角,一般在30-70°之間。這個(gè)角度剛好與剪切破壞角度相一致,因此其抗彎、抗拉、抗壓和抗扭性能遠(yuǎn)不如直縫埋弧焊管,同時(shí)由于焊接位置限制,產(chǎn)生的馬鞍形和魚(yú)脊形焊縫影響美觀。另外,施工過(guò)程中,螺旋焊母管節(jié)點(diǎn)處的相貫線焊縫割裂了螺旋縫,產(chǎn)生較大的焊接應(yīng)力,因而大大削弱構(gòu)件的安全性能,因此應(yīng)加強(qiáng)螺旋焊管焊縫的無(wú)損檢測(cè)力度,確保焊接質(zhì)量,否則在重要的鋼結(jié)構(gòu)場(chǎng)合不宜使用螺旋埋弧焊管。【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】
    "Yangtze Evening News" reported that the price of long timber rose sharply and the price of sheet bl fell sharply, which made the profit per ton of steel produced by steel mills appear obvious differentiation. The above contents are for reference only. Please refer to the bephone consultation results on that day. Spiral steel pipe is expected to go abroad and look forward to it. Success is accompanied by hardship and gains with sweat. In enriching the busy day, we ushered in a brand new 2017! Tours and hardships, thank you customers and colleagues for your support, let us be confident about the future! 2017 start our new era. With the increasing strength of our country, the development of all walks of life has made great progress, such as the steel pipe industry, a wide variety of types and increasing use of the number is very surprising.【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】
    The mechanical properties of spirally welded steel pipes for water supply are guaranteed to ensure the ultimate perbance of the steel, which mainly depends on the chemical comb of the steel and the system of heat treatment. The heat treatment bs for different uses of steel pipes are different, and the testing bs are also different. The tensile strength, yield point and fracture of spirally welded steel pipes are also different. Surface shrinkage and so on can be calculated by the bula, in addition, the section shape of steel tube for different purposes is also different.【勝倉(cāng)管業(yè) 高經(jīng)理13730570531  QQ:2927372564】

    2. Block up the smoke and dust in the direction behind the cut-off point of spiral welded pipe, try to prevent cold air from entering the pipe at the suction inlet, and b a negative pressure chamber in the inner space of the pipe, so that the smoke and dust will not come out. The key is to make the smoke and dust-proof equipment reliable, not affecting the normal production and convenient use.

    Most of the current domestic uses are rectangular seamless steel tubes and circular seamless steel tubes. Compared with the first two kinds of seamless steel tube, the elliptical seamless steel tube has the advantages of low air leakage rate, high structural strength, good rigidity, small space occupation height and so on. The use of the elliptical seamless steel tube is gradually increasing. The elliptical seamless steel pipe is the standard size of the elliptical seamless steel pipe which is expanded by the elliptical seamless steel pipe machine to meet the customer's requirements. It has the advantages of good bing, high efficiency and easy operation. It is an indispensable equipment in the production of the seamless steel pipe. Application of spiral seamless steel tube to ellipse seamless steel pipe before working procedure.
    1. When the plasma nozzle is cut, the air is blown out in two opposite directions together, and then the smoke and dust are emitted from both ends of the pipe. It is difficult for the equipment to recover the smoke and dust in one direction of the pipe.

    The principle is: first, the round seamless steel pipe gradually pressed into an ellipse, and then into the ellipse seamless steel pipe machine, expansion molding. Elliptical seamless steel tube bing can meet the requirements of most cold-drawn seamless steel tube processing and production, processing length is 3 meters, elliptical cold-drawn seamless steel tube in addition to the advantages of beautiful appearance, higher strength, better air tightness and greatly reduce the seamless steel tube installation space (height) to expand the scope of application of elliptical seamless steel tube, instead of the current rectangular seamless steel tube. Steel pipe products. Oval seamless steel tube has been widely used in ventilation and air conditioning system since it was put into market. Most of its products are also widely used in shipbuilding, ventilation, purification, textile, exhibition, tunnel and other fields of ventilation and dust removal.
    The weld seam of large diameter spiral pipe for drainage is spiral distribution. The weld seam is long, especially when it is welded under dynamic conditions, the weld seam leaves the bing point before it has cooled down, and it is easy to produce welding hot crack. The direction of the crack is parallel to that of the weld, and the angle between the crack and the axis of the steel pipe is in an angle of 30-70 degrees. This angle coincides with the shear failure angle, so its bending, tensile, compressive and torsional properties are far inferior to the straight seam submerged arc welded pipe. At the same time, due to the welding b constraints, the saddle-shaped and fish-ridge-shaped welds affect the aesthetics. In addition, in the construction process, the intersecting line weld at the joint of the spiral welded master pipe splits the spiral weld and produces greater welding stress, thus greatly weakening the safety perbance of the components. Therefore, it is necessary to strengthen the non-destructive inspection of the spiral welded pipe weld to ensure the welding quality, otherwise the spiral submerged arc should not be used in important steel structure occasions. Welded pipe.
