China is the main shipbuilding base in the world and has a complete shipbuilding industry system. With the continuous development of the shipbuilding industry, shipbuilding gantry crane as an indispensable lifting equipment, its performance and quality requirements are getting higher and higher. However, the metal structure of the shipbuilding door machine is affected by dust, humid air, acid and alkali gas and sun exposure all the year round, which will cause great security risks, so it is very important to do a good job of anti-corrosion. So, do you know the harm of corrosion and how to do a good job of anti-corrosion? Next, iron mountain crane for you to explain!

What are the hazards of corrosion of shipbuilding portal machines?

Oxide skin is not clear clean, welding surface defects, rust is not removed, not in the steel structure on the surface of the timely painting, oil is not removed or not clean... these reasons will cause the shipbuilding door machine suffered corrosion hazards. Specifically, corrosion will reduce the thickness of the cross-section, resulting in a large local rust pit, resulting in stress concentration, the emergence of early structural failure phenomenon; so that the steel structure fatigue, and brittle enhancement, resulting in a substantial decline in the body carrying capacity.

How to do a good job of shipbuilding door machine anti-corrosion?

1. Coating paint

One more layer of primer than conventional paint coating process; The adhesion between the coatings on the surface of the body is increased to twice the standard; Strictly abide by the quality control requirements of the new process for paint construction.

2. Anti-corrosion and anti-wear measures for electrical and hydraulic components

The use of 316L stainless steel material to make Fu outer shell, cable trough, joints, fuel tanks, etc., to enhance its corrosion resistance and wear resistance.

3. Anti-corrosion and anti-wear measures of fasteners

Use stainless steel with high anti-corrosion and anti-wear grade to make bolts of M14 and below; add washers under the nuts to avoid direct contact between the nuts and the steel plate to prevent damage to the surface paint when tightening the nuts.

4. Anti-corrosion and anti-wear measures for ladders, platforms and railings

Use FRP products to lay steps and walkway grilles; use solid round steel for railings; paint ladders, railings and platforms after integral hot-dip zinc processing; inclined ladders and straight ladders are installed by assembly to reduce welding points.

5. Anti-corrosion and anti-wear measures for structural parts

Seal the box body for the parts that are easy to rust, and take into account the future inspection, maintenance and update when designing the parts that are easy to rust. Set up drainage device to ensure the smooth flow of leakage holes and avoid local water accumulation.

The above is the anti-corrosion knowledge of shipbuilding gantry crane summarized by Tieshan crane for you. Tieshan crane reminds you that there should be no negligence in every step of the design, manufacture, spring storage and transportation of the shipbuilding gantry crane, and before using the shipbuilding gantry crane, you must do a good job in the safety knowledge and skills training of the operators, and strengthen the regular maintenance of the equipment to reduce potential safety hazards, so as to make your construction work safer and smoother.
