FBE epoxy powder anticorrosive steel pipe not only has excellent inductive function and strong corrosion resistance, but also uses external temperature of - 40 The suitable temperature for transporting water is -30 C - C. Epoxy powder anticorrosive steel pipe has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and coating mechanical strength. FBE epoxy powder of fused epoxy powder anticorrosive steel pipe is fluidized fully in a fluidized bed, and then sprayed electrostatically to make the powder particles charged negatively and evenly attached to the surface of the grounded preheated steel pipe. With regard to a small amount of slack powder, it can be recovered through the recovery system, and no dust pollution will be formed. There is a kind of coating called heavy-duty anti-corrosion epoxy powder coatings, it can also be called fused epoxy powder, foreign generally referred to as FBE,* was developed in the 1950s, completed industrial production in the 1960s, after so many years of continuous improvement, this coating has been developed to more old. Due to the problem of adhesion of epoxy powder impregnation process, the impregnation of epoxy powder has not been carried out. In recent years, with the successful development of special phosphating solution for epoxy powder immersion molding of Sancoco, the adhesion problem of epoxy powder immersion molding process was overcome for the first time, and the new technology of epoxy powder immersion molding was presented at the beginning. Epoxy powder coating is a new anticorrosive coating developed over the past 30 years.

燕趙新聞網(wǎng)今日報(bào)道：FBE環(huán)氧粉末防腐鋼管不僅具有優(yōu)異的歸納功用和很強(qiáng)的耐腐蝕性，運(yùn)用外界溫度為-40℃—氏度。適用輸水溫度為-30℃—℃。環(huán)氧粉末防腐鋼管具有不用溶劑、無污染、節(jié)省能源和資源、減輕勞動強(qiáng)度和涂膜機(jī)械強(qiáng)度高檔特征。熔結(jié)環(huán)氧粉末防腐鋼管FBE環(huán)氧粉末先在流化床內(nèi)充分流化，然后經(jīng)過靜電噴，使粉末顆粒帶負(fù)電，均勻地豁附在接地的經(jīng)預(yù)熱的鋼管表面。關(guān)于少量渙散的粉末，可經(jīng)過回收體系回收，不會形成粉塵污染。管道防腐中有一種涂料叫做重防腐環(huán)氧粉末涂料，它還可以稱作為熔結(jié)環(huán)氧粉末，國外一般都簡稱為FBE，*早是開發(fā)于20世紀(jì)50年代，60年代完成了工業(yè)化出產(chǎn)，經(jīng)過這么多年的不斷完善，此涂料現(xiàn)已展開較為老到。由于環(huán)氧粉末浸塑工藝受附著力問題困擾,環(huán)氧粉末的浸塑一向沒能推行。近年來跟著三椰環(huán)氧粉末浸塑專用磷化液開發(fā)成功,初度攻克了環(huán)氧粉末浸塑工藝的附著力難題,開端呈現(xiàn)環(huán)氧粉末的浸塑這一新式工藝。環(huán)氧粉末外涂層是*近30年來展開起來的新式防腐層。

Thermoplastic powder coatings. Thermoplastic powder coatings began to appear in 1950. It melts at spraying temperature and solidifies into films when cooled. Because of the simplicity of the processing and spraying methods, powder coatings need only be melted, leveled, cooled or solidified into films by heating, or solidified by extraction, without complicated solidification devices. Most of the raw materials used are common polymers on the market, which can meet the performance requirements under most conditions. But there are also some shortcomings, such as high melting temperature, low coloring level, poor adhesion with metal surface and so on. Nevertheless, the commonly used thermoplastic powder coatings still show some unique properties, among which polyolefin powder coatings have excellent solvent resistance; polyvinylidene fluoride coatings have outstanding weatherability; polyamide has excellent wear resistance; polyvinyl chloride has a good price / performance ratio; thermoplastic polyester powder coatings It has the advantages of beautiful appearance and high artistry. These characteristics make thermoplastic powder coatings occupy a large proportion in the coatings market.

熱塑性粉末涂料。熱塑性粉末涂料是1950年開始出現(xiàn)的，它在噴涂溫度下溶融，冷卻時(shí)凝固成膜。由于加工和噴涂方法簡單，粉末涂料只需加熱熔化、流平、冷卻或萃取凝固成膜即可，不需要復(fù)雜的固化裝置。大多使用的原料都是市場上常見的聚合物，多數(shù)條件下都可滿足使用性能的要求。但也存在某些不足，諸如熔融溫度高，著色水平低，與金屬表面粘著性差等。盡管如此，常用的熱塑性粉末涂料仍表現(xiàn)出一些特有的性能，其中聚烯烴粉末涂料具有極好的耐溶劑性；聚偏氟乙烯涂料具有突出的耐候性；聚酰胺具有優(yōu)異的耐磨性；聚氯乙烯具有較好的價(jià)格/性能比；熱塑性聚酯粉末涂料具有外觀漂亮、藝術(shù)性高等優(yōu)點(diǎn)。這些特性使熱塑性粉末涂料在涂料市場中占有很大比例.

環(huán)氧粉末防腐鋼管生產(chǎn)過程質(zhì)量檢驗(yàn) a)生產(chǎn)過程中的每一道工序都是保證產(chǎn)品質(zhì)量的必要環(huán)節(jié)。保證本道工序質(zhì)量，監(jiān)督上道工序質(zhì)量，是生產(chǎn)過程質(zhì)量檢驗(yàn)的重要環(huán)節(jié)。每道工序都要有嚴(yán)格的檢驗(yàn)，并要做好檢驗(yàn)記錄。b)鋼管內(nèi)表面預(yù)處理的質(zhì)量是影響防腐層與鋼管之間粘結(jié)的重要因素，要求100％檢查。除銹質(zhì)量檢查方法采用目測或內(nèi)窺鏡檢查，與 GB/T8923中的圖片或標(biāo)準(zhǔn)試片對照，判定是否達(dá)到質(zhì)量要求；如果除銹沒有達(dá)到要求應(yīng)重新處理。c)防腐層外觀的檢查應(yīng)用目測或用內(nèi)窺鏡逐根檢查防腐層外觀質(zhì)量，其表面應(yīng)平整、光滑，無氣泡、無劃痕等。d)防腐層厚度檢測，防腐層實(shí)干后，應(yīng)用無損檢測儀在距管口大于mm范圍內(nèi)沿圓周方向均勻分布任意4點(diǎn)上測量厚度，每10根管抽查1根。厚度是內(nèi)防腐層質(zhì)量指標(biāo)中最重要的一項(xiàng)指標(biāo) 必須確保防腐層的厚度。防腐層是阻止和延緩腐蝕的一道屏障，是保證管道在設(shè)計(jì)壽命內(nèi)正常運(yùn)行的最重要的一項(xiàng)指標(biāo)。目前大都采用無損檢測儀測量防腐層厚度，其準(zhǔn)確度會受到防腐層變形的影響。因此，在測量厚度時(shí) 應(yīng)在防腐層完全實(shí)干后進(jìn)行；在測量防腐層厚度前 必須按儀器說明書上的要求選用適當(dāng)?shù)臉?biāo)準(zhǔn)片進(jìn)行核準(zhǔn)，標(biāo)準(zhǔn)片一般儀器自帶、由于無損檢測儀的局限性 內(nèi)部防腐層的檢測有一定的困難，只能在管端進(jìn)行檢測。 e)防腐層漏電檢測：防腐層實(shí)干后，按照《管道防腐層檢漏試驗(yàn)方法》SY/T0063規(guī)定的方法逐根檢測.直縫鋼管是一種籠統(tǒng)得叫法，方式用鋼帶生產(chǎn)，在高頻焊接設(shè)備直縫焊接的管子都叫直縫鋼管 。（由于鋼管的焊接處成一條直線故而得名）。 其中按照用途不同，又不同的后道生產(chǎn)工序.(大致可分為腳手架管，流體管，電線套管，支架管，護(hù)欄管等幾種） 而低壓流體焊管是直縫焊管的一種，一般用水，煤氣的輸送， 在焊接完畢后比普通焊管多加以一道水壓測試，故而低壓流體管比普通直縫焊管價(jià)格一般高出一點(diǎn)（按現(xiàn)在的市場價(jià)來說，大概高出80元左右） 例如：焊接鋼管流體1寸（DN25）（就是Φ33.5*3.25) 焊接鋼管：也叫焊管，是用鋼板或鋼帶經(jīng)過彎曲成型，然后經(jīng)焊接制成。按焊縫形式分為直縫焊管和螺旋焊管。按用途又分為一般焊管、鍍鋅焊管、吹氧焊管、電線套管、公制焊管、托輥管、深井泵管、汽車用管、變壓器管、電焊薄壁管、電焊異型管和螺旋焊管。 一般焊管：一般焊管用來輸送低壓流體。用Q19、Q215、Q23鋼制造 。也可采用易于焊接的其它軟鋼制造。鋼管要進(jìn)行水壓、彎曲、壓扁等實(shí)驗(yàn)，對表面質(zhì)量有一定要求，通常交貨長度為4-10m，常要求定尺（或倍尺）交貨。焊管的規(guī)格用公稱口徑 表示（毫米或英寸）公稱口徑與實(shí)際不同，焊管按規(guī)定壁厚有普通鋼管和加厚鋼管兩種，鋼管按管端形式又分帶螺紋和不帶螺紋兩種，為焊接鋼管尺寸。
