BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, EN steel grade S690QL material steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, EN steel grade S690QL material chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, EN steel grade S690QL material steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

ASTM A516 is also known as ASME SA516. The A516 / SA516 standard specification for pressure vessel plates, carbon steel, for moderate- and lower-temperature service. A grade EN steel grade S690QL material intended primarily for service in welded pressure vessels where improved notch toughness is required, and is normally found in moderate and lower temperature applications. All plates over 1-1/2″ Thick are required to be normalized. A516 Grade 70 steel is the most popular pressure vessel grade of steel plate in the industry.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials EN steel grade S690QL material used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
