Description
技术领域
本发明属于管道施工技术领域,具体的说,尤其涉及一种多重增强钢塑复合压力管横缝焊接装置及施工方法。
背景技术
多重增强钢塑复合压力管(以下简称“多重管”)现场运行中出现的泄漏主要是横缝泄漏,横缝泄漏是指多重管对口完成后,使用电热熔带包裹熔区进行焊接后形成的C字型口部位泄漏。其主要原因是使用注塑枪对横缝进行焊接时,由于管道本体温度不够,达不到聚乙烯的熔融温度,使得管道本体与注塑枪的熔融塑料不能完全结合为一体,形成空腔,介质从管道接口渗出后,从横接缝处流出造成泄漏。
发明内容
本发明目的在于提供一种多重增强钢塑复合压力管横缝焊接装置及施工方法,以解决多重增强钢塑复合压力管横接缝泄漏的技术问题。
为解决上述技术问题,本发明的一种多重增强钢塑复合压力管横缝焊接装置的具体技术方案如下:
一种多重增强钢塑复合压力管横缝焊接装置,包括热熔板和恒温热熔器,热熔板通过螺栓连接固定在恒温热熔器上。
所述恒温热熔器通电后热熔器表面发热。
所述恒温热熔器上有安装孔,能够与热熔板通过螺栓固定在一起。
所述热熔板的材质为金属。
优先的,热熔板的材质为黄铜。
所述热熔板上部轮廓与恒温热熔器一致。
所述热熔板底部呈弧形,弧度与所焊接管道弧度相同。
一种多重增强钢塑复合压力管横缝焊装置的应用,应用时,横缝焊接的位置为多重增强钢塑复合压力电热熔带包裹后的C字型口部位。
本发明提供的一种多重增强钢塑复合压力管横缝焊装置的施工方法,包括以下步骤:
1)将管道进行对口并使用拉紧器固定,两个管口之间保留2-3mm的缝隙;
2)将热熔板使用螺栓固定到恒温热熔器上;
3)将恒温热熔器连接电源开始预热,此时绿色指示灯变黄灯,同时开始预热注塑枪;
4)预热3-5分钟后,恒温热熔器上的黄灯变灭,红色指示灯亮起,将热熔板上的弧形部分放置到管口接缝处,待接缝处塑料熔融后,按压热熔板,使得热熔板弧形部分的上沿将热熔塑料挤压成V型,熔深约2-3mm,时间8-12秒;
5)移动热熔器沿管周方向依次焊接,焊接长度为管周的1/4;
6)趁着管道的余热,使用注塑枪对横缝进行注塑焊接。
该施工方法,首先使用本发明的焊接装置进行第一次焊接,然后再使用注塑枪二次焊接,大大减少了横接缝处泄漏的情况;并且在焊接过程中,使管道本体带有温度,使得管道本体与注塑枪的熔融塑料可以完全结合为一体,增加了焊接的效果,又进一步防止横接缝处泄漏,相比于现有的施工方法,该方法进行了双重保障,操作简单,降低了运营成本。
本发明与现有技术相比,具有以下优点:在焊接电热熔带前先使用恒温热熔器对管道对接缝进行熔融焊接,然后使用注塑枪再次注塑焊接,焊接位置为电热熔带包裹后的C字型口部位,本发明能够解决现场管道横缝泄漏的难题,施工过程简单快捷,提高了焊接质量,彻底解决了横缝的泄漏问题,极大的减少了运营损失。

如图1所示,本发明公开了一种多重增强钢塑复合压力管横缝焊接装置,包括恒温热熔器1和用于给横缝加热的热熔板3,热熔板3通过螺栓2连接固定在恒温热熔板1上。
作为本发明一个优选的实施例,如图1所示,所述恒温热熔器1上有安装孔,能够与热熔板3通过螺栓2固定在一起,恒温热熔器通电后热熔器表面发热,并将热量传递给热熔板3。所述热熔板的材质为黄铜,能够快速吸收热熔器的热量。所述热熔板3上部轮廓与恒温热熔器1一致,能够较好地传递恒温热熔器1的热量。所述热熔板3底部呈弧形,弧度与所焊接管道弧度相同,能够完全贴合管道,保证了焊接质量。
如图2所示,本发明还公开了一种多重增强钢塑复合压力管横缝焊接施工方法,包括以下步骤:
1)将管道进行对口并使用拉紧器固定,两个管口之间保留2mm的缝隙
2)将热熔板3使用螺栓固定到恒温热熔器1上;
3)将恒温热熔器1连接电源开始预热,此时绿色指示灯变黄灯,同时开始预热注塑枪;
4)预热5分钟后,恒温热熔器1上的黄灯变灭,红色指示灯亮起,将热熔板3上的弧形部分放置到管口接缝处,待接缝处塑料熔融后,轻轻按压热熔板3,使得热熔板3弧形部分的上沿将热熔塑料挤压成V型,熔深约3mm时间10秒。
5)移动热熔器1沿管周方向依次焊接,焊接长度为管周的1/4。
6)趁着管道的余热,使用注塑枪对横缝进行注塑焊接。
采用本技术方案:恒温热熔器1通电后将热量传递给热熔板3,热熔板3放置到管道对接处,待管壁熔融后,逐步移动热熔板3,焊接长度为管周长的1/4,然后使用注塑枪再次注塑焊接。焊接位置为电热熔带包裹后的C字型口部位,本发明能够解决现场管道横缝泄漏的难题,施工过程简单快捷,提高了焊接质量,彻底解决了横缝的泄漏问题,极大的减少了运营损失。
