Abstract
The utility model relates to a flanged joint type lining teflon pipeline and a bend and a reducing pipe. The flanged joint type lining teflon pipeline and the bend and the reducing pipe are characterized in that flange discs are respectively connected on pipelines through threads at the butt joint end positions of two pipelines, and the flange discs are connected together through a bolt. A sealing gasket is arranged between two flange discs. The flanged joint type lining teflon pipeline and the bend and the reducing pipe have the advantages of being solid in connection, good in corrosion effect and convenient to dissemble due to the fact that the sealing gasket coated with a teflon layer and a wrapping pad are arranged at connection end positions.
Description
Technical field
The utility model relates to a kind of joint, and concrete is a kind of flange join type inner liner polytetrafluoroethylene pipeline, elbow and reducer.
Background technique
In technical fields such as oil, chemical industry, anticorrosion most important for pipeline is in the prior art, the joint that exists exists and connects unstable problem, and the pipeline at butt end place causes coming off of anticorrosive coat owing to reasons such as installation, dismountings, the serious working life that has affected pipeline.
The model utility content
For overcoming the defective of prior art, the utility model provides a kind of flange join type inner liner polytetrafluoroethylene pipeline, elbow and reducer that is connected firmly with corrosion-resistant effect that have.The technical solution of the utility model is: a kind of flange join type inner liner polytetrafluoroethylene pipeline, elbow and reducer, it is characterized in that: flange plate has been threaded respectively on the pipeline at place, the butt end of two pipelines, described flange plate is bolted together, between two flange plate sealing gasket is installed.
The inside of described two pipelines all is lined with internal lining pipe, and described internal lining pipe extends radially outwardly respectively at the place, butt end, forms extension part, is equipped with between described two extension parts and coats pad, between described extension part and the flange plate sealing gasket is installed.
The periphery of described internal lining pipe, sealing gasket and/or coating pad scribbles polytetrafluoroethylene floor.
The utility model has the advantages that: be connected firmly, in the port that connects, antiseptic effect is obvious, can adapt to abominable working environment simultaneously, such as environment such as high temperature resistant, anti-strong acid and highly basic.
