Stainless Steel Pipe-Encyclopedia

304 and 316L stainless steel materials are the only health materials that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. In the immersion water test, all the indicators meet the requirements of the relevant national drinking water standards. Stainless steel pipeline has smooth inner wall, no fouling, no bacterial contamination, anti-bacterial, anti-seismic, anti-tension, high pressure and high temperature resistance, no need to worry about water quality, and can prevent secondary pollution of water.Thin wall stainless steel water supply pipe is recognized as one of the best pipes with comprehensive properties

為什么不銹鋼水管大家都首選304材質(zhì)不銹鋼呢?

2020/4/23 9:36:00

提到高溫軸承,很多人可能不是很熟悉,它在機械行業(yè)應(yīng)用較多,但是高溫軸承往往一般需要使用潤滑,你知道使用什么潤滑比較好嗎?  提到不銹鋼水管,市場上很多人首選的就是304不銹鋼水管,那么你知道為什么大家都要首選304不銹鋼水管嗎?今天小編就圍繞這一問題跟大家談?wù)劇?/span>

    一、在價格上。一般而言304不銹鋼水管價格是相對居中且性價比高的。430不銹鋼(鐵)由于不含鎳元素,所以價格較為便宜。在300系不銹鋼里面,304的價格,相比于304L和316,價格要相對便宜,304L就是低C不銹鋼,生產(chǎn)工藝的差別造成價格比304不銹鋼貴,而316L不銹鋼由于含有MO(鉬)元素,使其耐蝕性、和高溫強度有較大的提高,但其價格就相當昂貴。

    二、連接方式。目前不銹鋼水管的連接一般分為焊接式連接,螺紋式連接方式,壓接式連接方式,焊接式施工麻煩,現(xiàn)場必須使用電,其焊接的部位溫度高容易岀現(xiàn)貧鉻現(xiàn)象,現(xiàn)場又不能進行固溶處理,使焊接部位容易生銹,而且這種焊接連接方式成本較高,一般用在厚壁和大口徑管道上。螺紋式連接方式,加工程序多,精度要求大,一般適用于厚壁不銹鋼管或需要活接處,擠壓式連接是目前不銹鋼水管應(yīng)用最多的方式,有環(huán)壓連接,卡壓連接,卡粘等。

    三、加工性能。430不銹鋼由于機械性能與工藝性能較差,拉伸加工后表面會出現(xiàn)軋鋼方向條狀缺陷。316不銹鋼強度高,容易塑性加工。304不銹鋼具有加工性能好,韌性高的特點,加工十分的方便,對于管件也容易進行設(shè)計。304L其加工性能和304類似,但由于碳元素含量低,在焊接后或者消除應(yīng)力后,其抗晶界腐蝕能力優(yōu)秀,在未進行熱處理的情況下,亦能保持良好的耐蝕性。

    目前大多中小口徑的不銹鋼水管都是采用薄壁有縫管,由制管機把切好的鋼帶制成規(guī)定的尺寸,而管材之間就用管件連接,管件需要擴口,需要彎曲,對不銹鋼材質(zhì)的加工性能要求較高。安裝的便利也是人們使用時很注重的一個點,專門為薄壁不銹鋼管研制的壓接式連接方式就快捷方便,連接效果好且安全可靠。

    從以上內(nèi)容我們能夠了解到,不管是在成本上,還是加工連接上,304不銹鋼水管都有著一定的優(yōu)勢,這也是為什么很多人會首選的原因。
