Abstract

The invention provides a hydraulic pipe fitting antirust process, comprising the following steps: a. removing impurities, placing the hydraulic pipe fitting in the pretreatment liquid and soaking for 10-30 minutes; b. cleaning, cleaning the hydraulic pipe fitting with warm water at 50-60°C Clean; c, soaking, place the cleaned hydraulic pipe fittings in the anti-rust solution and soak for 1-2 hours; d, cleaning, rinse the hydraulic pipe fittings soaked in the anti-rust liquid with clean water; e, dry, clean them The final hydraulic pipe fittings are dried in a dryer; f, frosting treatment, frosting the outer surface of the dried hydraulic pipe fittings; g, packaging, packaging the frosted hydraulic pipe fittings. The hydraulic pipe fitting antirust process of the present invention has simple process, convenient operation, good antirust effect and long service life of the hydraulic pipe fitting.

Description

technical field [0001] The invention relates to a metal surface antirust process, in particular to a hydraulic pipe fitting antirust process. Background technique [0002] Hydraulic pipe fittings are components that connect high-pressure oil pipes to high-pressure oil pipes in the hydraulic system. Due to its specific working environment, the hydraulic pipe fittings have high requirements on its anti-rust effect. The anti-rust process in the prior art is relatively complicated and the anti-rust effect is poor. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide an anti-rust technology for hydraulic pipe fittings which is easy to operate, has good anti-rust effect and can increase the service life. [0005] 【2】Technical solution to solve the problem [0006] An antirust process for hydraulic pipe fittings, comprising the following steps: [0007] a. To remove impurities,...
