How to remove rust from high strength weldable steel plate

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the high strength weldable steel plate construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU high strength weldable steel plate steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the high strength weldable steel plate project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of high strength weldable steel plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

The difference between Q195 steel and 20# steel: high strength weldable steel plate, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

The allowable temperature of high strength weldable steel plate, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of high strength weldable steel plate work, the actual stress of high strength weldable steel plate under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of high strength weldable steel plate under the temperature.

We have our own factory, including the production and manufacturing of steel pipes, with a special high strength weldable steel plate steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect high strength weldable steel plate after-sale service guarantee system, lets the customer save the worry and the labor.

Both parties shall confirm the high strength weldable steel plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the high strength weldable steel plate steel plant.
