Embodiment 1

[0024] see figure 1 , the present invention provides a technical solution for the surface treatment process of corrosion-resistant alloy seamless steel pipes: a surface treatment process for corrosion-resistant alloy seamless steel pipes, the steps are as follows:

[0025] Step 1: Degreasing: In the seamless steel pipe processing operation room, the seamless steel pipe is put into the degreasing area by the mechanical arm for degreasing. The degreasing time in the oil area is 2 minutes, and the standard is clean;

[0026] Step 2: Derusting: Before derusting, it is necessary to preheat the seamless steel pipe to be derusted and sandblasted, and uniformly heat the seamless steel pipe through the ring heater to ensure that the temperature of the bottom and side of the steel pipe should be consistent, and the heating temperature should be no The product specification of the seam steel pipe is used as the guideline, and the derusting operation is carried out by sandblasting. The ...

Abstract

The invention discloses a surface treatment process of a corrosion-resistant alloy seamless steel tube, and the process comprises the following steps: in a seamless steel tube processing operation room, putting a seamless steel tube into an oil removal area through a mechanical arm to remove oil, holding an alcohol cleaning agent in the oil removal area, and removing oil of the seamless steel tubein the oil removal area for 2 minutes until the seamless steel tube is completely removed; carrying out a derusting operation in a sand blasting manner; enabling the mechanical arm to transport the seamless steel tube subjected to oil removal from the oil removal area to the rust removal area for centralized rust removal treatment, enabling a sand blasting gun to be perpendicular to the axis of the preheated seamless steel tube, enabling the sand blasting gun to reciprocate at a constant speed along the axis of the pipeline, and stopping the gun when the surface of the seamless steel tube isin a metal natural color and has no black or red spots, wherein the coating comprises primer coating, intermediate paint coating and finish paint coating; enabling a quality inspector to inspect whether a paint film has pinholes, bubbles, cracks, shedding, sagging and missing coating or not, and storing the paint film in a warehouse after the paint film is inspected to be qualified. The surface ofthe seamless steel tube can be efficiently treated, so the safe use is achieved.

Description

technical field [0001] The present invention relates to the technical field of xxx, in particular to a surface treatment process for corrosion-resistant alloy seamless steel pipes. Background technique [0002] Steel pipes made of a single piece of metal without seams on the surface are called seamless steel pipes; according to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, jacking pipes, etc.; According to the cross-sectional shape, seamless steel tubes are divided into two types: round and special-shaped, and special-shaped tubes have various complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes. The maximum diameter is 650mm, and the minimum diameter is 0.3mm. Depending on the application, there are thick-walled tubes and thin-walled tubes. [0003] Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for ...
