    洛陽梓哲管材有一支技術(shù)部門,可對(duì)鋼襯四氟管道 鋼襯PE管道 襯塑管道 鋼襯PO管道 襯膠管道等化工管尾礦管以及石油類、食藥類用管的圖紙,草圖,樣圖,自畫圖進(jìn)行解析,分析出需要的管材管件規(guī)格尺寸等。我公司有著豐厚的制作經(jīng)驗(yàn)以及一對(duì)一的服務(wù),我們也可委派工程進(jìn)入現(xiàn)場(chǎng)進(jìn)行圖紙繪畫和測(cè)量。

    Luoyang Zizhe pipe has a technical department, which can analyze the drawings, sketches, samples and self drawn drawings of chemical pipes such as steel lined Teflon pipes, steel lined PE pipes, plastic lined pipes, steel lined Po pipes and rubber lined pipes, tailings pipes and pipes for petroleum and food and medicine, and analyze the required pipe specifications and dimensions. Our company has rich production experience and one-to-one service. We can also appoint projects to enter the site for drawing and measurement.?

     襯塑管即鋼塑復(fù)合管,是以普通碳素鋼管作為基體,內(nèi)襯化學(xué)穩(wěn)定性優(yōu)良的熱塑性塑料管(常用PE、PO、PVC、PTFE),經(jīng)冷拉復(fù)合或滾塑成型,市場(chǎng)上采用的是滾塑成型。?鋼襯塑管道滾塑成型又稱旋塑即旋轉(zhuǎn)成型、旋轉(zhuǎn)模塑、旋轉(zhuǎn)鑄塑、回轉(zhuǎn)成型等。是先將塑料原料加入模具中,然后模具沿兩垂直軸不斷旋轉(zhuǎn)并使之加熱,使模內(nèi)的塑料原料在重力和熱能的作用下,逐漸均勻地涂布、熔融粘附于模腔的整個(gè)表面上,成型為所需要的形狀,再經(jīng)冷卻定型、脫模, 獲得制品。從而使得它既有鋼管的機(jī)械性能,又有塑料管的耐腐蝕,緩結(jié)垢,不易生長(zhǎng)微生物的特點(diǎn),是輸送酸、堿、鹽、有腐蝕性氣體等介質(zhì)的理想管道

    Plastic lined pipe, i.e. steel plastic composite pipe, is a thermoplastic pipe (commonly PE, Po, PVC and PTFE) with ordinary carbon steel pipe as the matrix and excellent chemical stability. It is cold drawn, compounded or roll molded, and roll molded is adopted in the market.? Rotational molding of steel lined plastic pipe is also called rotational molding, that is, rotational molding, rotational casting, rotational molding, etc. Firstly, the plastic raw materials are added into the mold, and then the mold rotates continuously along the two vertical axes and heats it, so that the plastic raw materials in the mold are gradually and evenly coated, melted and adhered to the whole surface of the mold cavity under the action of gravity and heat energy, formed into the required shape, cooled, shaped and demoulded, and finally obtained the product. Therefore, it not only has the mechanical properties of steel pipe, but also has the characteristics of corrosion resistance, scale inhibition and difficult growth of microorganisms of plastic pipe. It is an ideal pipeline for transporting acid, alkali, salt, corrosive gas and other media
