詳細(xì)介紹

PP彎頭
在PP通風(fēng)管路系統(tǒng)中，PP彎頭是改變管路方向的管件。按照生產(chǎn)工藝可分為：模壓彎頭、注塑彎頭、承插彎頭等。其他名稱：90度彎頭、直角彎、愛而彎等。按角度分，有45°及90°180°三種的，另外根據(jù)工程需要還包括60°等其他非正常角度彎頭。彎頭與管子聯(lián)結(jié)的方式有：直接焊接（的方式）法蘭聯(lián)接、熱熔連接、電熔連接、螺紋聯(lián)接及承插式聯(lián)接等。
PP彎頭曲率半徑：PP彎頭在PP通風(fēng)管道系統(tǒng)中，是改變管道方向的管件。PP彎頭英文為Elbow，縮寫為E。因材質(zhì)的不同，生產(chǎn)工藝不一樣，相對(duì)應(yīng)的規(guī)格參數(shù)也不一樣，從而PP彎頭的分類也多種多樣?，F(xiàn)以曲率半徑為主要分類點(diǎn)，分析彎頭管件的分類以及表示方法。按照曲率半徑來分類可分為長(zhǎng)PP半徑彎頭和PP短半徑彎頭。PP長(zhǎng)半徑彎頭指它的曲率半徑等于1.5倍的管子外徑，即R=1.5D。PP短半徑彎頭指它的曲率半徑等于管子的外徑，即R=D。公式中的D為PP彎頭直徑，R為曲率半徑。LR表示長(zhǎng)半徑，SR表示短半徑。按PP彎頭的角度分，有45°彎頭，有90°彎頭和180°彎頭。
PP對(duì)焊彎頭：PP對(duì)焊彎頭是塑料粒子模壓成型的彎頭，它的連接形式就是接將彎頭與PP管對(duì)焊連接。國(guó)際標(biāo)準(zhǔn)ISO161和化工部標(biāo)準(zhǔn)?？筛鶕?jù)客戶的需求另行加工制作。采用模壓成型，產(chǎn)品具有強(qiáng)度高，耐腐蝕，氣密性好，使用壽命長(zhǎng)，安裝維修方便等特點(diǎn)；具有耐腐蝕、耐高溫、質(zhì)輕無毒、無污染，強(qiáng)度高，無縫、操作靈敏、零部件拆換方便，價(jià)格低等優(yōu)勢(shì)，能廣泛應(yīng)用于石油、化工、氯堿、冶煉、制藥、電鍍。等行業(yè)，產(chǎn)品深得用戶好評(píng)。
PP elbow
In the PP ventilation line system, the PP elbow is a pipe that changes the direction of the pipe. According to the production process, it can be divided into: molding elbow, injection elbow, socket elbow and so on. Other names: 90 degree elbow, right angle bend, love and bend. According to the angle, there are three most commonly used 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. The way in which the elbow is coupled to the pipe is: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection. PP elbow radius of curvature: PP elbow is a pipe fitting that changes the direction of the pipe in the PP ventilation duct system. PP elbow English is Elbow, abbreviated as E. Due to different materials, the production process is different, and the corresponding specifications are different, so the classification of PP elbows is also diverse. Now use the radius of curvature as the main classification point to analyze the classification and representation of elbow fittings. According to the radius of curvature, it can be divided into long PP radius elbow and PP short radius elbow. The PP long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D. The PP short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R=D. D in the formula is the diameter of the PP elbow, and R is the radius of curvature. LR represents a long radius and SR represents a short radius. According to the angle of the PP elbow, there is a 45° elbow with a 90° elbow and a 180° elbow. PP butt weld elbow: PP butt weld elbow is an elbow molded by plastic particles. Its connection form is to connect the elbow to the PP pipe butt weld. International standard ISO 161 and Ministry of Chemical Industry standards. Can be processed separately according to customer needs. With compression molding, the product has the characteristics of high strength, corrosion resistance, good air tightness, long service life, convenient installation and maintenance, etc. It has corrosion resistance, high temperature resistance, light weight, no toxicity, no pollution, high strength, seamless and sensitive operation. It is easy to replace parts and components, and has low price. It can be widely used in petroleum, chemical, chlor-alkali, smelting, pharmaceutical and electroplating. In other industries, the products have won praise from users.
