Od194mm Wt 35mm Top Quality API 5L/ASTM A106 Gr. B/A53 Steel Pipe Carbon Seamless Steel Pipe

An overview of the Seamless carbon steel pipes:

(1) Manufacturing method:

① The general boiler tube temperature is below 350℃, domestic pipe is mainly made of No. 10, no. 20 carbon steel hot rolled pipe or cold drawn pipe.

(2) High-pressure boiler tubes are often used under high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, oxidation and corrosion will occur. The steel pipe is required to have high durable strength, high oxidation corrosion resistance and good microstructure stability.

(2) use:

(1) General boiler tube is mainly used to manufacture water wall tube, boiling water tube, superheated steam tube, locomotive boiler superheated steam tube, large and small smoke pipe and arch brick pipe.

(2) High pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, pipe, main steam pipe, etc.

(2)GB5310-95 "Seamless steel tube for high pressure boiler" provisions. Chemical composition test method according to GB222-84 and "Method for Chemical Analysis of Iron and Steel and Alloy", GB223 "Method for chemical analysis of Iron and Steel and Alloy".

(3) Chemical composition inspection of imported boiler steel pipe shall be carried out according to relevant standards stipulated in the contract.

The double-face seal is lubricated by an external closed-loop supply system. The mechanical seal is specially designed for heavy duty seal applications. The sealing surface is doubly balanced; In the event of a drop in spacer pressure or a high pressure transient in the seal chamber, the seal remains closed, allowing the pump to stop operation without the risk of sealing surface damage or product contamination of the atmosphere. The operation characteristics of the same static ring assembly when the operating conditions change. The seal is designed to be integrated so it is compact, rugged and easy to maintain. Corrosion can be avoided by selecting suitable sealing surface materials and structural parts materials. Silicon carbide is usually used as the sealing surface material because of its high hardness and excellent thermal conductivity.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second".
