What is the difference between S690QL hardness, carbon steel pipe and seamless steel pipe? Carbon steel pipe, the performance of this kind of steel pipe is controlled by the amount of carbon content. Different carbon content has different properties and uses. Carbon steel pipe can be seamless or seam welded. Seamless steel pipe is a large category of steel pipe, which can include carbon seamless steel pipe, low alloy seamless steel pipe, high pressure boiler pipe, oil cracking pipe and so on.
Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, S690QL hardness. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
