Material requirements for API 650 carbon and low-alloy steel tanks

The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API 650 carbon and low-alloy steel tanks steel plate reaches the standard and the service life is longer.

The insert plate weld shall not cross any shell seams and shall be at least the greater of 10 times the shell thickness or 12 in. from any other weld in the API 650 carbon and low-alloy steel tanks shell including shell seams, shell-to-bottom weld or attachment welds. The butt weld around the periphery of the plate shall be examined over 100% of its length by both liquid penetrant method and radiographic method. The liquid penetrant examination is required on the root pass, on the back-gouged surface, and on the inside and outside finished weld surfaces. Additionally, the weld shall be vacuum box leak tested.

The factors affecting the "small breathing" loss of API 650 carbon and low-alloy steel tanks are: 1. It is related to the change of temperature difference between day and night. The greater the change of temperature difference between day and night, the greater the loss of "small breathing"; on the contrary, the smaller the change of temperature difference between day and night, the smaller the loss. 2. It is related to the sunshine time of the oil storage tank. The longer the sunshine, the more the "small breathing" loss; otherwise, the less the loss.

Continue to refine and improve the company's common core values.Corporate values are the evaluation criteria for the production and operation behavior, products, services provided, social reputation and credit of enterprises, the biggest API 650 carbon and low-alloy steel tanks goal pursued by enterprises and the criteria for judging things accordingly, and the core of corporate culture. Companies in the extraction of common value note: simplicity; Unity of coordination; API 650 carbon and low-alloy steel tanks Systemic; Respect for talents; Focus on giving back to society; Try to make a factual argument in order to gain wider acceptance.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API 650 carbon and low-alloy steel tanks steel materials can be shipped immediately after passing the quality inspection.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
