S690QL1 steel grades for pressure vessels

Seamless steel pipe refers to the steel pipe made of a whole piece of metal without joints on the surface. According to the production method, it can be divided into hot rolling tube, cold rolling tube, cold drawing tube, S690QL1 steel grades, extrusion tube and spinning tube. According to the shape of the section, it can be divided into two types: circular and irregular. The seamless tube has a maximum diameter of 650 mm (expanding tube) and a minimum diameter of 0.3 mm (capillary tube), which can be divided into thick walled tube and thin walled tube according to the thickness.

The company's main business: ship plate, S690QL1 steel grades low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, S690QL1 steel grades high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional S690QL1 steel grades steel supplier and partner.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image S690QL1 steel grades processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the S690QL1 steel grades steel plate.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S690QL1 steel grades.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel S690QL1 steel grades plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
