燕趙新聞網(wǎng)（楊編輯）今日報(bào)道，TPEP是一種防腐結(jié)構(gòu)，是*一應(yīng)用于長距離輸水管道的防腐形式，與傳統(tǒng)輸送管道對比，具有諸多優(yōu)勢特點(diǎn)，管道外防腐為3PE,管道內(nèi)防腐為熔結(jié)環(huán)氧粉末，管道內(nèi)壁的防腐標(biāo)準(zhǔn)達(dá)到了食品級(jí)。河北潤成管道生產(chǎn)的TPEP防腐鋼管工程按照國家標(biāo)準(zhǔn)施工可以埋地使用50年保證管道正常使用。TPEP防腐鋼管--外3PE內(nèi)熔結(jié)環(huán)氧防腐鋼管是在外單層聚乙烯內(nèi)環(huán)氧復(fù)合鋼管的基礎(chǔ)上升級(jí)換代產(chǎn)品，是目前埋地長輸管線*的鋼管防腐形式。TPEP is a kind of anticorrosion structure. It is an anticorrosion form used in long-distance water pipeline. Compared with traditional pipeline, TPEP has many advantages. The anticorrosion outside pipeline is 3PE, the anticorrosion inside pipeline is fused epoxy powder. The anticorrosion standard of pipeline inner wall reaches food grade. The TPEP anticorrosive steel pipe project produced by Hebei Runcheng pipeline can be buried and used for 50 years in accordance with the national standards to ensure the normal use of the pipeline. TPEP anticorrosive steel pipe - outer 3PE inner melted epoxy anticorrosive steel pipe is an upgraded product based on outer monolayer polyethylene inner epoxy composite steel pipe. It is the anticorrosive form of steel pipe for buried long distance pipeline.tpep防腐鋼管是滄州勝倉管業(yè)有限公司自主開發(fā)的第四代大口徑管道新型防腐生產(chǎn)線，外壁采用熱熔結(jié)纏繞工藝底層環(huán)氧樹脂、中間層膠黏劑、外層聚乙烯形成三層結(jié)構(gòu)的防腐層，內(nèi)壁采用熱噴涂環(huán)氧粉末防腐方式，將粉末經(jīng)高溫加熱熔結(jié)后均勻地涂敷在管體表面上，形成鋼塑合金層，簡稱TPEP鋼管，。極大提高了涂層附著力及涂層厚度，增強(qiáng)了耐磕碰，耐腐蝕的能力。該產(chǎn)品于2009年獲取國家實(shí)用新型專利。2年獲得國家火炬項(xiàng)目。TPEP鋼管填補(bǔ)了國內(nèi)鋼管*防腐的空白，價(jià)格與單層聚乙烯內(nèi)熔結(jié)環(huán)氧復(fù)合鋼管相差無幾，耐腐蝕能力提高了3-5倍。

The TPEP anticorrosive steel pipe is a new type of anticorrosive production line of the fourth generation large diameter pipeline developed by Cangzhou Shengcang Pipe Industry Co., Ltd. The exterior wall adopts hot-melt winding technology to form a three-layer structure anticorrosive coating of epoxy resin at the bottom layer, adhesive at the middle layer and polyethylene at the exterior layer, and the interior wall adopts thermal spraying epoxy powder anticorrosive method to pass the powder through After heating and melting, the alloy is evenly coated on the surface of the tube to form a steel plastic alloy layer, or TPEP steel tube. The adhesion and coating thickness of the coating are greatly improved, and the resistance to bumping and corrosion resistance is enhanced. The product acquired the national utility model patent in 2009. 2 years won the national Torch Program. TPEP steel pipe fills the blank of domestic steel pipe * anticorrosion. The price of TPEP steel pipe is almost the same as that of single-layer polyethylene inner-melted epoxy composite steel pipe, and the anticorrosion capacity is increased by 3-5 times.TPEP防腐鋼管該涂層還可根據(jù)需要進(jìn)行機(jī)械加工，并可以用在動(dòng)態(tài)部件上，增強(qiáng)部件的耐磨、耐氣蝕、耐沖刷性能，提高部件在苛刻環(huán)境下的使用壽命經(jīng)過實(shí)際應(yīng)用考核和檢驗(yàn)，重腐蝕防護(hù)技術(shù)日臻成熟，解決了許多其它防護(hù)技術(shù)未能解決腐蝕問題，為國民經(jīng)濟(jì)可持續(xù)發(fā)展做出了重要貢獻(xiàn)，可在以下領(lǐng)域廣泛應(yīng)用：長距離輸運(yùn)油、水、氣等埋地管道防護(hù)；輸酸、堿、鹽和灰渣等腐蝕介質(zhì)的工藝管道和異型件的防護(hù)；泵、閥、風(fēng)機(jī)等設(shè)備的重腐蝕防護(hù)；供熱和輸海水管道波紋管補(bǔ)償器的腐蝕防護(hù)；海洋工程及碼頭鋼結(jié)構(gòu)件的防腐蝕；電解銅行業(yè)種板邊緣包覆；設(shè)備及管道損傷件的修復(fù)；長輸埋地管道補(bǔ)口。目前它已在“西氣東輸”管道彎管防腐工程、上海浦東天然氣管道防腐工程、秦山核電站海水管道、海艦艇海水閥門重點(diǎn)工程中得到應(yīng)用。專家認(rèn)為該系列涂料應(yīng)用廣泛，使用效果好、壽命長、使用無環(huán)境污染，在相關(guān)行業(yè)推廣使用將大幅度降低由于腐蝕引起的經(jīng)濟(jì)損失，必將產(chǎn)生顯著的經(jīng)濟(jì)效益和社會(huì)效益。TPEP anticorrosive steel pipe this coating can also be machined according to the needs, and can be used in dynamic components to enhance the wear resistance, cavitation corrosion resistance, erosion resistance of components, improve the service life of components in harsh environment through practical application examination and inspection, heavy corrosion protection technology is becoming more and more mature, and solve many other protection technologies. It can be widely used in the following fields: long-distance transportation of oil, water, gas and other buried pipelines protection; acid, alkali, salt and ash and other corrosive media pipelines and special parts protection; pump, valve, fan and other equipment heavy corrosion protection. Corrosion protection of corrugated pipe compensators for heating and seawater pipelines; corrosion protection of steel structural parts for marine engineering and wharf; seed plate edge coating for electrolytic copper industry; repair of damaged equipment and pipeline parts; repair of long-distance buried pipelines. At present, it has been applied in the pipeline bend anticorrosion project of "West-East Gas Transmission" pipeline, the natural gas pipeline anticorrosion project of Shanghai Pudong, the seawater pipeline of Qinshan Nuclear Power Station and the seawater valve key projects of naval vessels. Experts believe that this series of coatings are widely used, with good effect, long service life and no environmental pollution. It will greatly reduce the economic losses caused by corrosion in related industries, and will produce significant economic and social benefits.

傳統(tǒng)“金九”旺季需求，目前尚未如預(yù)期中的快速啟動(dòng)，國內(nèi)現(xiàn)貨鋼市受期市起落的影響，在一波下跌之后有所企穩(wěn)，總體依然呈窄幅下行的態(tài)勢。鐵礦石市場則在震蕩中有所上揚(yáng)。
  據(jù)國內(nèi)鋼鐵資訊機(jī)構(gòu)“我的鋼鐵”提供的最新市場報(bào)告，最近一周，國內(nèi)現(xiàn)貨鋼價(jià)綜合指數(shù)報(bào)收于163.16點(diǎn)，一周下跌0.01%。具體而言，周初，黑色系期貨市場高位回落，帶動(dòng)現(xiàn)貨鋼市的價(jià)格大幅下跌，市場成交也大幅下降。不過，到了周中和周末，期貨市場有所企穩(wěn)并呈小幅的反彈，現(xiàn)貨鋼價(jià)跟著小幅有所上行，市場成交也小幅有所回暖。
  據(jù)分析，在建筑鋼市場上，價(jià)格總體依然有小幅的上漲。全國主要市場主流規(guī)格螺紋鋼品種的均價(jià)為每噸4579元，一周上漲17元。從最新公布的庫存數(shù)據(jù)來看，建筑鋼的社會(huì)庫存小幅有所增加，但鋼廠的庫存則出現(xiàn)了回落，表明鋼廠的壓力不大，或?qū)⒗^續(xù)挺價(jià)，從而使得市場的到貨成本處于高位。
  在板材市場上，價(jià)格總體下行。熱軋板卷價(jià)格小幅下跌，全國主要市場主流規(guī)格熱軋產(chǎn)品的市場均價(jià)為每噸4357元，一周下跌31元。中厚板價(jià)格小幅下跌，全國主要市場主流規(guī)格普中板的平均價(jià)格為每噸4514元，一周下跌16元。目前“金九”旺季需求尚未完全開啟而市場的持貨成本卻較高，鋼市只能維持高位震蕩的運(yùn)行態(tài)勢。
  鐵礦石市場總體在震蕩中有趨強(qiáng)上揚(yáng)的走勢。據(jù)最新報(bào)告，在國產(chǎn)礦市場上，國內(nèi)鐵精粉價(jià)格大多堅(jiān)挺，北方有的地區(qū)延續(xù)上漲。進(jìn)口礦價(jià)先抑后揚(yáng)，截至13日，62%品位進(jìn)口鐵礦石價(jià)格為每噸69.25美元，周環(huán)比微漲0.4美元。港口進(jìn)口礦庫存結(jié)束了連續(xù)下降的狀況，出現(xiàn)了小幅的增長，市場成交總體并不太理想。
