본고안은 강관의 이음쇠의 부식방지 코어에 관한 것으로, 내식성이 요구되는 강관의 형성에 있어서의 특히, 소겟, 엘보, 티이 및 이경소켓등과 같이 관의 모든 이음 용접부위의 내경에 범람코어가 삽입 고정되도록 하는 동시에, 범람코어의 양쪽끝단부위에 내열팩킹에 의하여 유지되도록 하므로써, 관의 이음부위의 용접열에 의하여 내경의 피복층이 손상되는 것을 방지하여 파이프의 사용수명을 연장할 수 있는 강관의 이음쇠의 부식방지 코어에 관한 것이다.This paper relates to the anti-corrosion core of the fittings of steel pipes, in which the flooding core is inserted into the inner diameters of all the joint welds of the pipes, such as sogets, elbows, tee and two-hole sockets, in the formation of steel pipes requiring corrosion resistance. It is fixed and maintained at both ends of the overflow core by heat-resistant packing, thereby preventing the damage of the inner diameter coating layer from being damaged by the welding heat of the joint of the pipe, thereby extending the service life of the pipe. It relates to an anticorrosion core.

일반적으로 유체가 공급되는 대략 15~1000mm의 직경의 파이프에 부식의 방지를 위하여, 내,외경에 에폭시코팅 및 폴리에틸렌코팅층으로 피복하는 것이 일반적이다.In general, in order to prevent corrosion in pipes having a diameter of about 15 to 1000 mm to which fluid is supplied, it is common to coat the inner and outer diameters with an epoxy coating and a polyethylene coating layer.

또한 관의 이음부재(100)인 소켓, 엘보,티이 및 이경소켓등에도 제1도에 나타낸 바와 같이 상기와 같이 내, 외경에 에폭시코팅 및 폴리에틸렌코팅층으로 피복층(30)을 형성하여, 부식을 방지할 수 있도록 하고 있다.In addition, as shown in FIG. 1, a socket 30, an elbow, a tie, and a two-hole socket, which are pipe joint members 100, is formed with an epoxy coating and a polyethylene coating layer on the inner and outer diameters as described above to prevent corrosion. I can do it.

상기 이음부재(100)의 경우에는 파이프의 연결을 위하여 플랜지(10)가 용접에 의하여 고정되도록 하는데, 용접에 의하여 피복층이 타버려 파이프의 내면의 보호가 제대로 이루어지지 않는 결점이 있다.In the case of the joint member 100, the flange 10 is fixed by welding in order to connect the pipes, and the coating layer is burned by welding, and thus the inner surface of the pipe is not properly protected.

또한, 제2도의 경우에는 이음부재(100)에 에폭식도장코어(20)가 삽입 고정되도록 하고 있으나, 이 역시 상기 에폭식도장코어(20)는 플랜지(10)의 용접시 용접열에 의하여 코어에 도장된 에폭식 도장면이 용접열에 의하여 도장이 타버리기 때문에, 이 또한 도장의 의미를 상실하게 되는 문제가 있으며, 또한 에폭식도장코어(20)의 바깥면과 이음부재(100)의 내경과의 틈이 발생되어 그사이로 물등의 유체가 스며 들어가 용접열로 파손된 파이프 내면에 녹이 발생되어 파이프 수명이 단축되고 녹물이 발생되는 등의 문제가 있었다.In addition, in the case of FIG. 2, the epoxy coating core 20 is inserted into and fixed to the joint member 100. However, the epoxy coating core 20 is connected to the core by welding heat during welding of the flange 10. FIG. Since the painted epoxide coated surface is burned out by the heat of welding, this also causes a problem that the meaning of the coating is lost. Also, the outer surface of the epoxy coated core 20 and the inner diameter of the joint member 100 are separated. There was a problem that a gap was generated and fluid, such as water, penetrated between them, causing rust on the inner surface of the pipe damaged by welding heat, shortening pipe life and generating rust.

본고안은 상기의 결점을 해소하기 위한 것으로, 이음부재의 내, 외경에 에폭시코팅 및 폴리에틸렌코팅층으로 피복층이 코팅되도록 하면서, 이음부재의 플랜지가 용접되는 부위의 내경에 900℃의 고열처리의 범람코어가 삽입되어 고정되도록 하는 동시에, 부가하여 범람코어가 이음부재의 내경과 내열팩킹에 의하여 긴밀하게 유지되도록 하므로써, 유체의 누수를 방지시켜 범람코팅이로 수질에 아무 변형을 주지않으면서 용접된 부위의 손상된 면을 보호할 수 있는 강관의 이음쇠의 부식방지 코어를 제공 하고자 한다.This study is intended to solve the above-mentioned drawbacks, while the inner and outer diameters of the joint members are coated with an epoxy coating and a polyethylene coating layer, while the inner core of the flange where the flanges of the joint members are welded is heated at 900 ° C. at a high heat treatment. Is inserted and fixed, and in addition, the overflow core is closely held by the inner diameter of the joint member and the heat-resistant packing, thereby preventing the leakage of fluid, so that the overflow coating does not deform the water quality of the welded portion. It is intended to provide a corrosion resistant core of steel pipe fittings that can protect damaged surfaces.

본고안은, 내식성이 요구되는 소켓, 엘보, 티이 및 이경소켓 등의 강관의 형성에 있어서, 관의 내, 외경에 에폭시코팅 및 폴리에틸렌코팅층의 피복층이 형성된 이음부재의 내경에 범람코어가 삽입 고정되도록 하는 동시에, 상기 이음부재의 내경에 범람코어가 내열팩킹에 의하여 긴밀하게 유지될 수 있도록 됨을 특징으로 한다.In this proposal, in the formation of steel pipes such as sockets, elbows, tie and two-hole sockets requiring corrosion resistance, the overflow core is inserted into and fixed to the inner diameter of the joint member in which the coating layer of the epoxy coating and the polyethylene coating layer is formed on the inner and outer diameters of the tube. At the same time, it is characterized in that the flooding core in the inner diameter of the joint member can be maintained closely by the heat-resistant packing.

The overflow core 40 in the inner diameter is to be maintained closely by the heat-resistant packing 50.

상기 범람코어(40)는 90oC열에 견디는 재질로써 이음부재(100)에 플랜지(10)의 용접시에 충분히 용접열에 견딜 수 있고, 또한 내열팩킹(50)역시 실리콘 등의 내열재료를 사용할 수 있다.The flooding core 40 is a material that withstands 90 ° C heat and can withstand welding heat sufficiently during welding of the flange 10 to the joint member 100, and the heat-resistant packing 50 may also use a heat-resistant material such as silicon. have.

또한, 범람코어(40)의 바깥둘레에는 내열팩킹(50)이 장착될 수 있는 요홈링(60)이 형성되어 내열팩킹(50)을 유지할 수 있도록 되어 있다.In addition, the outer periphery of the overflow core 40 is formed with a groove ring 60 to which the heat-resistant packing 50 can be mounted to maintain the heat-resistant packing 50.

상기와 같이 구성된 본고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

피복층(30)이 형성된 이음부재(100)의 내경에 범람코어(40)가 삽입 고정되도록 하는 동시에, 상기 이음부재(100)의 내경에 범람코어(40)가 내열팩킹(50)에 의하여 긴밀하게 유지될 수 있도록 되어 있기 때문에, 용접에 의하여 손상된 용접부위를 범람코어(40)에 의하여 보호되어 2중으로 내경을 보호하는 효과가 있는 것이고, 또한 범람코어(40)의 양쪽부위가 내열성의 내열팩킹(50)에 의하여 유지되어 유체의 침투를 방지할 수 있는 이점이 있다.The overflow core 40 is inserted into and fixed to the inner diameter of the joint member 100 on which the coating layer 30 is formed, and the overflow core 40 is tightly connected to the inner diameter of the joint member 100 by the heat-resistant packing 50. Since it is possible to hold, the welded part damaged by welding is protected by the overflow core 40 to protect the inner diameter twice, and both parts of the overflow core 40 are heat-resistant heat-resistant packing ( It is maintained by 50) has the advantage of preventing the penetration of the fluid.

이상과 같이, 본고안은 이음부재의 내,외경에 에폭시코팅 및 폴리에틸렌코팅층으로 피복층이 코팅되도록 하면서, 이음부재의 플랜지가 용접되는 부위의 내경에 900℃의 고열처리의 범람코어가 삽입되어 고정되도록 하는 동시에, 부가하여 범람코어가 이음부재의 내경과 내열팩킹에 의하여 긴밀하게 유지되도록 하므로써, 유체의 누수를 방지시켜 범람코팅이로 수질에 아무 변형을 주지 않으면서 용접된 부위의 손상된 면을 보호할 수 있는 것이다.As described above, the present proposal is to coat the coating layer with the epoxy coating and polyethylene coating layer on the inner and outer diameters of the joint member, while the flooding core of 900 ℃ high heat treatment is inserted and fixed to the inner diameter of the portion where the flange of the joint member is welded. At the same time, the overflow core is kept tight by the inner diameter and heat-resistant packing of the joint member, thereby preventing the leakage of fluid and protecting the damaged surface of the welded portion without any deformation of the water quality by the overflow coating. It can be.
