The bimetal thermometer is when the bimetal feels a temperature change, the pointer can indicate the temperature on a circular graduated scale, and can directly read the data, which is very intuitive and convenient. Therefore, the scope of application of bimetal thermometers is very wide, such as petroleum, chemical, machinery, shipbuilding and other fields. However, it is necessary to pay attention to the misunderstanding of bimetals in applications so as not to affect the accuracy of the measurement results. Then we need to understand the misunderstanding of bimetal thermometers .
1, high temperature range:
The temperature range of the bimetal thermometer is 200~650°C, and the allowable error is about 1% of the scale range. In fact, this is not correct, because this type of metal sheet is made of a spiral coil shape heat-conducting sensor. It will easily fatigue at a high temperature of 650°C, and the temperature difference is very large. Therefore, when the temperature exceeds 550°C, thermocouples should be considered. To solve this problem.
2, the lowest temperature range
The temperature range of the bimetal thermometer is 200 ~ 650 °C (this is not correct), the lowest temperature can be measured to -40 °C. In fact, this is not much, because the bimetal thermometer is usually calibrated at -20°C during production.

Ship Building Steel Plate

Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion of seawater, electrochemical corrosion and corrosion of marine organisms and microorganisms; the hull is subjected to large wind and wave impacts and alternating loads; the shape of the ship is complicated by processing methods, etc. Steel for hull structure is strictly required. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, weldability, forming properties and surface quality are required.

Shipbuilding Steels Our hot rolled shipbuilding steel is produced in accordance with the relevant Classification Society, examples of which include Lloyds Register and Det Norske Veritas.

Our steel products include steel shipbuilding plate, fabricated steel sections and floor plate for decking. We can also supply bulb flats for plate stiffening, structural steel angles and inverted angles.

Our plates are supplied under the ASTM/ASME specification (ASTM A131 / ASME SA 131) which is the standard specification for Structural Steel for Ships. We offer higher strength shipbuilding steels as standard .High strength steels offer significant cost advantages by reducing the weight of the structure in comparison to the steel used.

The plates are suitable for use in the construction of container ships and large cargo freighters as well as commercial shipping lines such as luxury cruise ships and ferries. Supply options include heavy plates, surface treated plates and pre-fabricated sections. In most cases, the steel can also be supplied as hot rolled coils or cut into lengths (sheets).

These high yield materials are commonly used in the construction of hulls and superstructures for large shipping vessels. The grades are exclusively for shipbuilding use as set out in the standard.
