Marine Steel Plate refer to the steel used to manufacture the hull structure of sea-going ships and inland watercrafts, usually high-quality carbon steel and high-quality low-alloy steel. Marine steel plate is required to have certain strength, toughness, and low temperature resistance and corrosion resistance, as well as good welding performance.

General strength hull structure steel is divided into 4 grades: A, B, D, E. The yield strength (not less than 235N/mm^2) and tensile strength (400~520N/mm^2) of these 4 grades of steel The same, but the impact energy is different at different temperatures.
High-strength hull structure steel is divided into strength grades according to its minimum yield strength, and each strength grade is divided into A, D, E, F 4 grades according to its impact toughness.
Due to the harsh working environment of the ship, the hull of the hull is subject to seawater chemical corrosion, electrochemical corrosion, marine organisms, and microbial corrosion; the hull bears greater wind and wave impact and alternating loads; the shape of the ship makes the processing method complicated, so it is not Shipboard steel plates have strict requirements. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality are required.
High strength shipbuilding steel grades include AH, DH, EH, and FH with a specified minimum yield point of 46 ksi [315MPa], 51 ksi [350MPa], or 57 ksi [390MPa].
Grades AH32, DH32, EH32 and FH32's yield strength is not less than 315MPa, and the tensile strength is 440~570Mpa. Grades AH36, DH36, EH36 and FH36's yield strength is not less than 355MPa, and the tensile strength is 490~620MPa. Meanwhile, the yield strength of AH40, DH40, EH40 and FH40 is not less than 390MPa, and the tensile strength is 510~660MPa.
High Quality Pneumatic Diaphragm Pump (metal)
Pneumatic Diaphragm Pump
The pneumatic diaphragm pump is designed with a simple and highly reliable air reversing valve, ensuring maximum performance and durability under various operating conditions. This three-way pilot valve guarantees smooth operation without any "sticking" issues, making it ideal for continuous use in harsh environments. All components can be replaced without opening the liquid chamber, simplifying maintenance and reducing downtime. The aluminum parts are treated with anodic oxidation and epoxy coating to resist corrosion from contaminated air, enhancing the pump's longevity.
Key Features:
1. The central shaft is integrated for better concentricity and smoother movement.
2. An improved filter unit ensures stable air motor operation.
3. The air-guided plate is made of ceramic and stainless steel, suitable for different working environments.
4. The piston end uses a no-screw design for easier installation.
5. The external air motor is easy to maintain and service.
6. Engineering-grade plastic is used to reduce material waste and improve efficiency.
7. Fewer moving parts compared to other diaphragm pumps, increasing reliability.
8. A single reversing valve is compatible with multiple pump models, offering flexibility.
9. The air motor comes with a 15-year warranty, while the pump body has a 5-year warranty.
