Marine Engineering

Rather than the first, it is better to be the only.

Connectors such as joints play a very important role in fluid systems, they are bridges connecting different pipelines. In order to ensure the normal operation of the entire system, the connectors need to meet the requirements of easy installation, disassembly and repeated installation, and have a leak-free air-tight seal. Depending on the environment in which the system is to be used, there is also a need for connectors that can be used in corrosive environments or extreme temperatures.

When the system is exposed to and in contact with highly corrosive corrosive chemicals, the standard fittings can corrode severely, putting the entire assembly at a higher risk of early failure, in severe cases causing the equipment to fail to function properly and causing excessive downtime, etc. as a result of.


what corrosion can bring

direct economic loss

Interruption of normal work

Difficulty in maintaining equipment

Threats to staff health

For a long time, corrosion and friction problems have not only restricted the development level of many industrial fields such as marine, chemical, biological engineering, mechanical processing, transportation, aerospace, etc., but also caused the explosion of the Palper Alpha oil rig and the Sinopec Qingdao Donghuang oil pipeline. Road leaks, the derailment of the German high-speed rail ICE 884 and other major disasters.


Advantages of tantalum plating materials

Traditional austenitic stainless steels are not resistant to stress corrosion, chloride attack, and especially sulfide cracking. This limits the application of the connector in many environments. To solve this problem, it is urgent to find corrosion-resistant materials.


Tantalum is recognized as the most corrosion-resistant metal. The surface alloy prepared by AINS vapor-phase tantalum evaporation technology has the physical properties of tantalum metal, which can effectively improve the mechanical properties of the substrate, with excellent deformation and bending ability, unparalleled corrosion resistance, high temperature resistance, high pressure performance , is the best choice for harsh working conditions.
