Cold Rolled Stainless Steel Tubes And Pipes Suppliers For Shipbuilding Industry

In the shipbuilding industry, stainless steel pipes have become an integral part, bringing many advantages to ship construction.

01. Improving Construction Efficiency

First, stainless steel marine pipes play a key role in improving the efficiency of ship construction. The internal space of ships is often very limited, and the traditional on-site processing and installation of pipelines require a lot of time and space, which undoubtedly increases the construction time and cost. By pre-processing and welding the pipes at the factory, the time and space requirements for on-site installation can be greatly reduced, thus saving a lot of time and costs. This has brought significant benefits to the shipyard, improved construction efficiency, and reduced production costs.

02. Improvement Of Welding Quality

Another significant advantage of stainless steel marine pipes is improved welding quality. When prefabricating in the factory, advanced welding equipment and professional welding workers can be used to ensure that the welding quality reaches the standards. In contrast, on-site welding conditions are often restricted, making it difficult to ensure the stability of welding quality. By using stainless steel pipes, the workload of rework and repair can be greatly reduced, and the efficiency of ship construction is improved.

03. Corrosion Resistance And Aesthetics

Stainless steel marine pipes also have good corrosion resistance and aesthetics. Since the working environment of ships is relatively complex, there are high requirements for the corrosion resistance and aesthetics of pipelines. Stainless steel materials have reliable corrosion resistance, and the processing and welding processes of stainless steel pipes can also ensure the aesthetics of the pipes. This provides a strong guarantee for the overall quality and appearance of the ship.

04. Expansion Of Application Scope

In addition, the application scope of stainless steel marine pipes continues to expand. Initially, stainless steel pipes were mainly used in the construction of large ships such as oil tankers and liquefied gas ships. With the continuous advancement of technology and reduction of costs, stainless steel pipes have now been widely used in various types of ship construction, including bulk carriers, container ships, etc. This further proves the importance and broad application prospects of stainless steel pipes in the shipbuilding industry.

In short, stainless steel marine pipes play an increasingly important role in the shipbuilding industry.

Characteristics and applications of stainless steel surface finish

Surface finish	Characteristics & Application
NO.1	Hot-rolled surface, annealed and pickled, can be used as cold-rolling material, industrial tanks, and chemical devices.
NO.2D	Cold-rolled, annealed and pickled with out skin passing the dull products can be used as auto mobile parts, building materials and piping.
NO.2B	The surface brightness and flatness of NO.2B are better than NO.2D. Then through a special surface treatment to improve its chemical properties, N0.2B. could nearly satisfy comprehensive uses.
NO.3	Polished with an abrasive belt of grit #100#120, have better brightness with discontinuous coarse stria, used as inner and external ornaments for buildings, electrical appliances kitchen utensils, etc.
NO.4	Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3. are used as bathtub building inner and external ornaments electrical appliances, kitchen utensils, food processing equipment, etc.
HL	Polished with abrasive belt of grit #150-320 on the No.4. finish and has continuous streaks, mainly used as building ornaments, elevators, doors of the building, frontal plate, etc.
BA	Cold-rolled, bright annealed and skin passed, the product has excellent brightness and good reflexivity like mirror, used for electrical appliances, kitchen apparatus, ornament materials, etc.
