Embodiment Construction

[0011] The present invention is further described below.

[0012] The present invention carries out according to the following steps:

[0013] 1. Pickling and rust removal: immerse the pipe in acid solution;

[0014] 2. Substrate preheating: the pipe runs at a constant speed in the pipe heating furnace and is evenly heated;

[0015] 3. Plastic dipping inside and outside: immerse 70% of the pipe in a fluidized bed containing fluidized powder for rotational molding and systemic coating;

[0016] 4. Heating leveling: Put the coated pipe into the heating leveling furnace;

[0017] 5. Test the finished product and pack it into the warehouse after passing the test.

[0018] The above-mentioned embodiments are only described to the preferred implementation mode of the present invention, and are not intended to limit the concept and scope of the present invention. Various modifications and improvements should belong to the protection scope of the present invention.

Abstract

The invention discloses a thermal impregnation processing technique for a power tube, which is capable of guaranteeing thickness uniformity of a coating. The thermal impregnation processing technique for the power tube is realized by using the following technical scheme, comprising the following steps of: pickling and derusting: soaking a tube material into acid liquor; substrate preheating: running the tube material in a tube heating furnace at a uniform velocity to be uniformly heated; internal and external impregnation: soaking 70% of the tube into a fluidized bed containing fluidization powder to mould rotationally and coating-mould by using internal suction; heating and leveling: putting the tube with coatings into a heating and leveling furnace; detecting the finished product, packaging and putting the qualified finished product in storage. In the invention, the internal surface and the external surface of the tube can be coating-moulded at the same time, so that the coating-mould time is shortened, the heat is utilized to the maximum extent and the uniformity of the coating thickness is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power threading pipe preparation, and more specifically relates to a hot-dipping plastic processing technology for electric power pipes. Background technique [0002] The existing power tube processing process is to pre-process the power threading tube and then perform internal dipping processing, and then perform external dipping processing. This requires a long time for plastic coating, which cannot maximize the use of heat, and cannot guarantee the thickness of the coating. Uniformity. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and to provide a hot-dip plastic processing technology for power tubes that can ensure the uniformity of coating thickness. [0004] The hot-dip plastic processing technology of the electric power tube of the present invention is realized through the following technical scheme,...
