The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

Grade DH36 ship steel plate is a high-strength ship plate. Shipbuilding steel generally refers to the steel used for hull structure. It refers to the steel used for manufacturing the hull structure produced in accordance with the requirements of the classification society construction codes. EN steel grade S690QL material, DH36 ship steel plate is often ordered, scheduled, and sold as special steel. We can supply various sizes and shapes of ship steel like plates , steel angles, bulb flat, steel channel and section steel.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld EN steel grade S690QL material steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for EN steel grade S690QL material manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

EN steel grade S690QL material, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.

The company uses outsourced logistics operations. Our cooperated professional third-party logistics providers use the advantages of large-scale production and cost advantages to achieve cost savings by increasing the utilization of resources in each link, so that we can benefit from the separation of cost structure. Therefore, we can also provide customers with better, faster and more efficient cargo transportation, delivery, and lower freight costs.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality EN steel grade S690QL material products and excellent services. Our company's products EN steel grade S690QL material are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
