FRPP管材簡介、特點、功能、規範

作者：admin 編輯：admin 來源：未知 2022-08-02 10:26

FRPP管材簡介、***點、功能、規範的概述：

簡介

FRPP管材（玻纖增強聚丙烯管材）用經偶聯劑處理的玻璃纖維改性聚丙烯資料生産，依據HG20539-92規範，規範De20-De800mm，公稱壓力0.4-1.0MPa，耐腐蝕、耐高溫、衛生無毒，可回收運用，適用于腐蝕性液體運送（如酸堿液）及市政給排水系統。具有較******的抗沖擊性和拉伸強度，重量輕。安裝修理便利。

管材規範

◇ FRPP管材执行HG 20539-92。

***點

◇ 长久的运用寿命-----在额外温度、压力情况下，FRPP管材可安全运用50年以上。

◇ 杰出的耐腐蚀功能-----FRPP管材本******多数化学物品的腐蚀，可在很***的范围内接受PH值范围在1-14的高浓度酸和碱的腐蚀。

◇ 较高的刚度-----因为加入了玻纤增强资料使FRPP管材不易变形。

◇ 耐热保温节能-----FRPP管材***运用温度95度，该产品的导热系数仅为钢管材的1/200，故有较***的保温功能。

◇ 可靠的衔接功能-----FRPP管材热熔接口的强度高于管材本体，接缝不会因为土壤移动或载荷的作用而断开。

◇ 杰出的施工功能-----FRPP管原料轻，焊接工艺简单，施工便利，工程归纳造价低。

銜接辦法

a FRPP管材的热风焊衔接

　　◇ 焊条资料的化学成分必须确保管材道焊接的强度要求。

　　◇ 热风焊接时，加热温度应契合以下规则：190-240℃

　　◇　焊條和焊接外表必須清潔、幹淨。

　　◇　焊條和管材必須同時處于熔融狀態進行焊接，不該有燒焦和分解現象。

　　◇　焊縫排列應嚴密，不該有空隙。

　　◇　焊縫外表應平坦，不該有波紋形及焊條吹毛現象。

　　◇　焊縫的強度不得低于設計規則的強度。

　　◇ 焊缝应天然冷却。

b FRPP管材的热熔对接衔接

　　◇ 热熔对接时管材的加热温度应契合以下规则：190-240℃

　　◇ 热熔对接时，将对接的管材子水平固定在对接设备的夹具上，使两根衔接管材坚持水平位置，而且两管材要对***中心。

　　◇ 热熔对接应选用具有调节温度的焊接设备。

◇ 依据管材原料控制热熔温度和热熔时刻。并坚持必定的对接推力。

◇ 热熔对接衔接面应天然冷却。

[Pg 86] There was the man who twice within the last hour had been in danger of his life chatting quietly with the man who had robbed him. The two were evidently on the best of terms, for Maitrank was laughing heartily, and Balmayne stood opposite smoking a cigarette like a host who speeds a parting guest. 225 As soon as we returned to Palitana the Rajah sent to inquire after me, and to present me with round boxes of fruit preserved in Cashmere, oval green grapes, each wrapped separately in cotton and smelling of honey. Dick echoed the cry. Jeff had already caught the threat of that swamp below them. They could not risk going a foot lower. The pilot opened his throttle, picking up climbing speed to the roar of his engine. “It’s a kind of sense that’s common enough—but——” “Why didn’t you tell me?” her cousin demanded. They all saw the captain’s face assume an expression of disgust. CHAPTER XXX DICK ENCOUNTERS THE “GHOST” They came around him and offered him their horses, dismounting even, and forcing the reins into his hands. "You don't know what you are doing," a corporal urged. "You'll never get out alive. If it ain't Indians, it'll be thirst." Then he looked into Cabot's face and saw that he did know, that he knew very well. And so they left him at last, with more of the tepid alkali water than they well could spare from their canteens, with two days' rations and an extra cartridge belt, and trotted on once more across the plain. Shorty had dropped on to a bench, and fixed his eyes on the stone wall opposite, as if desperately striving to read there some hint of extrication from his perplexities. The thought of encountering Maria's bright eyes, and seeing there even more than her sharp tongue would express, numbed his heart. "And will you do that alone?" With Richard things were different. He despised Reuben as bestial, and sometimes jeopardised his skin by nearly showing his contempt. He now had a peculiar friendship with Anne Bardon. They had met accidentally a second time, and deliberately half a dozen more. In Richard Anne had made a discovery—he appealed to her imagination, which ran on severe lines. She sympathised with his ambition to break free from the grind and grossness of Odiam, and resolved to help him as much as she could. She lent him books, and guided him with her superior knowledge and education. "The same, your grace, if my judgment be correct." At this moment a messenger rode up to Oakley, and, putting a letter into his hands, instantly retired. HoME 午夜伦理av男人的天堂wwww6080comENTER NUMBET 008www.mxkxc.com.cn
