Description
본 고안은 FRP 파이프, 엘보우, 리듀서와 플랜지 결합방법에 관한 것으로, FRP 수지와 글래스 매트의 함침에 의해 FRP 파이프, 엘보우, 리듀서와 플랜지를 결합하는 방법에 관한 것이다.The present invention relates to a FRP pipe, an elbow, a reducer and a flange coupling method, and to a method of coupling the FRP pipe, an elbow, a reducer and a flange by impregnation of a FRP resin and a glass mat.
이는 화학공장에서 일반자재로는 이송이 불가능한 염산, 황산 및 내화학 약품 등을 이송할 때 쓰이는 FRP 배관 제품이며, 기존에 문제 되어 오던 용접부위의 용액 침투로 인해 제품의 수명 단축 및 작업시 비산으로 인한 작업장 환경오염과 설비 부식 등을 방지하기 위함이며, 아울러 현장 용접 작업시 절단 및 사상작업으로 인해 발생되는 분진으로 인한 작업자의 건강위험요소와 현장 오염을 방지하고 현장작업의 신속성을 높여 조업의 안정성을 얻기 위한 것이다.This is a FRP piping product used to transfer hydrochloric acid, sulfuric acid and chemicals that cannot be transferred to general materials in chemical plants.It is shortened due to the solution penetration of the welding part, which has been a problem in the past. In order to prevent workplace environmental pollution and equipment corrosion due to worksite, and also to prevent worker's health risk factor and site contamination due to dust generated by cutting and finishing work during on-site welding work, and to increase the speed of on-site work and improve work stability. To get.
현재 이루어지고 있는 FRP 배관 제품의 생산은 대표적으로 두 가지 방법이 있다. 그 첫 번째는 FRP 플랜지와 파이프, 엘보우, 리듀서 등의 자재를 각각 생산하며, 현장여건에 맞도록 FRP 제품을 절단하여 각각의 제품의 연결 시 별도로 용접하여 사용하는 방법이고, 두 번째는 소켓 타입으로 파이프제품을 절단하여 엘보우, 플랜지, 리듀서 등을 삽입하여 연결부위를 파우더로 충진 하고 마무리 시 용접 하여 사용하는 방법이다.Currently, there are two methods for producing FRP piping products. The first is to produce materials such as FRP flanges, pipes, elbows, reducers, etc., and to cut FRP products according to the site conditions and weld them separately when connecting each product. The second is a socket type. It is a method of cutting pipe products, inserting elbows, flanges, reducers, etc. to fill the joints with powder and welding them to the finish.
위의 두 가지 형태의 제품 생산방법이 현재 대다수 이루어지고 있으나, 두 방법 모두가 가지고 있는 단점은 용접부위가 있고 그 부위 안쪽 절단면이 약품에 노출되어 있어 용액의 침투가 섬유 매트 층을 타고 빠르게 진행되어 수명이 약품에 따라 불분명하고 현장에서 절단하여 사용함으로서 절단 시 사용되는 그라인더로 인해 FRP 분진 등이 발생하며 그로 인해 작업자의 작업환경이 열악하고 현장 설비를 오염시키며 용접작업 후 동·하절기 온도에 따른 경화시간이 최저 30분에서 24시간으로서 작업시간을 조절하기 어려운 문제점 들이 발생되고 있었다.Most of the above two types of product production methods are currently made, but the drawbacks of both methods are the welding area and the cutting surface inside the area is exposed to the chemical, so that the solution infiltrates rapidly through the fiber mat layer. The service life is unclear according to chemicals and the FRP dust is generated due to the grinder used for cutting, which causes the worker's working environment to be poor, contaminating the on-site equipment, and hardening according to the winter and summer temperature after welding. As the time was at least 30 minutes to 24 hours, it was difficult to control the working time.
본 고안의 목적은 상기의 제반 문제점들을 해소하기 위한 것으로서 FRP 배관 제품을 플랜지와 플랜지를 현장에서 BOLT로 연결하면 설치 완료되는 FRP 파이프와 플랜지, FRP 엘보와 플랜지, FRP 리듀스와 플랜지를 각각 일체화 시키는 결합방법을 제공함에 있다. 이는 FRP 배관의 용접부위를 제거하여 연결부위로 침투하는 용액을 방지하여 제품의 사용 수명을 연장하고 현장 용접 작업 시 발생하는 분진으로 인한 설비오염방지 및 작업환경을 개선하여 별도의 용접 후에 경화시간이 필요 없게 하여 그에 따른 작업시간 단축 및 작업의 안정성과 신속성 그리고 작업능률을 향상시키기 위한 것이다.The purpose of the present invention is to solve the above problems and to integrate the FRP pipe products, FRP pipes and flanges, FRP elbows and flanges, FRP reducers and flanges, which are installed when the FRP piping products are connected to the flanges in the field by the BOLT. To provide a method of coupling. This prevents the solution from penetrating into the connecting part by removing the welding part of the FRP pipe, which extends the service life of the product, prevents equipment contamination due to dust generated during on-site welding work, and improves the working environment. It is to reduce the work time and improve the stability, speed and work efficiency accordingly.
상기 목적을 달성하기 위한 본 고안은, FRP 파이프의 한쪽 끝을 함침 몰드에 고정시키는 공정, FRP 수지와 글래스 매트를 번갈아 가며 함침 하는 공정, 파이프 끝부분의 플랜지를 경화시키는 공정, 함침 몰드를 탈형 시키는 공정으로 구성되었으며, 파이프의 반대쪽도 동일한 방법으로 하여 파이프와 플랜지를 일체화 시키는 공정으로 구성되어있다.The present invention for achieving the above object, the process of fixing one end of the FRP pipe to the impregnation mold, the process of alternately impregnating the FRP resin and glass mat, the process of curing the flange of the pipe end, demolding the impregnation mold It is composed of the process, and the other side of the pipe is composed of the process of integrating the pipe and the flange in the same way.
이하 본 고안의 실시예 도면을 첨부한다.It is attached to the embodiment of the present invention drawings.
이상에서 설명한 바와 같이 본 고안에 따른 FRP 파이프, 엘보우 리듀서와 플랜지 결합방법에 의하면, 현재 화학공장 및 약품을 이용하는 산업공장에서 이루어지는 FRP 배관 제품 설치 시 발생되는 분진으로 인한 작업자의 작업환경을 개선할 수 있으며, 현장오염을 최소화하여 설비오염을 방지하고, 배관의 용접부위를 제거하여 배관내의 유체에 의해 배관의 수명 단축을 방지하고, 배관 작업시 용접작업을 하지 않게 되어 용접부위의 경화시간이 필요 없는 관계로 작업시간을 단축시켜 작업능률을 향상 시킬 수 있는 효과가 있다.As described above, according to the FRP pipe, elbow reducer and flange coupling method according to the present invention, it is possible to improve the working environment of the worker due to the dust generated during the installation of FRP piping products in the current industrial plants using chemical plants and chemicals It minimizes site contamination to prevent facility contamination, removes welding parts of pipes, prevents shortening of pipe life by fluid in pipes, and does not require hardening time of welding parts because welding work is not performed during piping work. As a result, the work time can be shortened and the work efficiency can be improved.
