Process protection structure of a stainless steel oil suction well of a ship

Abstract

The invention relates to the technical field of shipbuilding, the invention discloses a process protection structure of a stainless steel oil suction well of a ship, includes a stainless steel suctionwell body, an erasable pre-weld protective layer is arranged on the surface of the oil suction well body, and a removable oil suction well pre-coating protective device arranged on the hull section where the oil suction well body is located, the protective layer before welding is a lime slurry layer painted on the surface of the oil absorption well body, the protective device for oil suction wellbefore coating comprises a protective plate covered on the oil suction well body, and magnetic rubber strips are arranged on the peripheral plane of the protective plate which is in contact with theoil suction well mounting connection plane of the hull section, and the magnetic rubber strips are glued and connected with the protective plate. The invention improves the manufacturing quality of the stainless steel oil suction well by setting the process structure of the stainless steel oil suction well.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a process protection structure for a stainless steel oil-absorbing well of a ship. Background technique [0002] The stainless steel oil suction well is an accessory on a large chemical tanker, which is usually welded on the inner bottom plate of the hull (the material is marine steel) section. [0003] In the prior art, there are the following problems when welding stainless steel oil-absorbing wells: First, the spatter during welding is relatively serious, and the molten welding is easy to splash metal to the inner surface of the stainless steel oil-absorbing well and stick to it, and the metal spatter will be left behind after cleaning. Many scars need more time for grinding and polishing to remove, and after grinding and polishing, the surface texture of the oil-absorbing well will be uneven, thereby affecting the appearance quality of the oil-absorbing well. The second...

Problems solved by technology

[0003] In the prior art, there are the following problems when welding stainless steel oil-absorbing wells: First, the spatter during welding is relatively serious, and the molten welding is easy to splash metal to the inner surface of the stainless steel oil-absorbing well and stick to it, and the metal spatter will be left behind after cleaning. Many scars need to be removed by grinding and polishing for a long time, and the surface texture of the oil absorption well will be uneven after grinding and polishing, thus affecting the appearance quality of the oil absorption well

The second is to paint after the hull is made in sections. The sandblasting before painting can easily roughen the inner surface of the stainless steel oil-absorbing well, thus affecting the quality of the inner surface of the oil-absorbing well.
