抱箍式低温支架在天然气放空管线中的应用
抱箍式低温支架在天然气放空管线中的应用摘要:结合天然气站场内放空管线的脱落现象,分析其成因,并介绍了采用抱箍式低温支架的设计过程及实际运行效果。
关键词:天然气放空管线脱落抱箍式低温支架LNG接收站高压加压单元的主要设施是高压泵,而站场外输天然气的动力来源主要来自高压泵的加压,目前普遍采取的是给LNG加压后直接气化外输。
在其工艺流程中,放空管线起着均衡压力的作用。
按其工艺设计原理,管道中应为气相天然气。
但实际运行过程中,往往其间是气液两相的混合体。
尤其在高压泵启停期间,随着LNG外输负荷变化引起的流量波动,流体经过弯头、异径、控制阀等部件,压降不同,转变成系统振动的激励源,如果激发频率和管道结构固有频率相近就会产生共振,会对管道造成不利影响。
因此,采取必要的措施固定放空管线是消除振动的有效途径。
在某天然气站场内,新增了2台高压泵。
而其中的新增高压泵区的DN200天然气放空管线上的3个低温支架,连同管道一道从钢结构支座上滑落。
(见图1)设计单位和低温支架制造单位派员来现场调研,并召开讨论会,分析原因。
经检查现场,核对设计资料,发现设计有错误。
设计院在设计这一段管道时,应力分析报告中12530设定为限位支架,轴向力36 KN,但在施工用图中,错误地表示为普通承重架,没有限位功能。
按照原工艺设计,天然气放空管线内应为低流速气相,但操作中发现时有LNG 流入,LNG在管内形成水锤冲击,造成了管线离位滑脱。
(见图2) 其中对管系附加的位移DX及DY达到29 mm,产生很大的位移应力。
根据应力分析计算,设计单位在会上提出了两种方案:(1)把此管线放空:管线放空后,管线的复位更容易,且更安全,此时焊接已成为可能,应把12530处的承重架恢复为限位架。
但管线放空需要把2台新高压泵中的一台也同时放空,工作量很大。
(2)DN200管线不放空:在这种情况下应把12570处的承重架改为导向架,此时增加水平推力650 kg,钢结构应加强。

0度时流量为0,90度是流量为最大。
可以配合AT31执行器配套使用，可选择三点式，或者连续信号控制，调整方便。
调节范围25:1从而达到烧嘴功率线性输出的目的线性流量调节阀是基于旋转阀芯的工作原理，流量调节柱形阀芯上有特使设计的线性流量通道。
通过调节阀芯的旋转来获得相应的流量AXF-25为简易线性阀，阀芯为筒材质，外形尺寸见AKL25。
AFX-40/30阀芯为筒材质。
AFX-25阀芯为塑料，线性度比AXF-25高。
