The SMA400AP steel exhaust pipe steel specification from BBN

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality SMA400AP steel exhaust pipe products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy SMA400AP steel exhaust pipe steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of SMA400AP steel exhaust pipe carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the SMA400AP steel exhaust pipe alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the SMA400AP steel exhaust pipe wear-resistant property to meet the requirements of specific working conditions.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

During the construction of hot-dip SMA400AP steel exhaust pipe galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the SMA400AP steel exhaust pipe construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

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.
