The low-temperature seamless steel pipe can work in the extremely cold environment of - 45~- 195℃. The outstanding advantage of low-temperature seamless steel pipe is that it can work in a very low environment, which is incomparable with ordinary seamless steel pipe. The low-temperature seamless steel pipe has good strength and low-temperature toughness, and is widely used in the manufacturing of low-temperature equipment in petroleum, chemical, fertilizer and other industries with a working temperature of - 45~- 195 ℃. With the development of relevant industries, the requirements for materials are not only limited to basic requirements such as mechanical properties and welding properties, but also the requirements for H2S corrosion resistance of low-temperature pipes.
Low-temperature seamless steel pipe is applicable to pipeline engineering in low temperature environment. There are two processes: cold drawing and hot rolling. From the perspective of steel design, the steelmaking, rolling, heat treatment and other processes of low-temperature seamless steel pipe should be strictly controlled to ensure that low-temperature seamless steel pipe has good strength, toughness and corrosion resistance. For the technical requirements of low-temperature seamless steel pipe, the production organization and production cost of the steel pipe should be comprehensively considered. The composition design of low-temperature seamless steel pipe needs to ensure that the product has appropriate strength, high low-temperature toughness, and convenient heat treatment process Good weldability and resistance to hydrogen-induced cracking.

1.Q: How long can make delivery?
A: For stock products, will make shipments in 5- 7 days after receiving deposit or receiving L/C;For products need new production for common materials, usually make shipments in 15-30 days; For products need new production for
special and rare materials, usually need 30-40 days to make shipment.
2.Q: Will the Test Certificate be certified to EN10210/EN10219?
A: For the new production products no need further cutting or processing, will provide the Original Mill Test Certificate
certified to EN10204 3.1; for the stock products and the products need cutting or further processing, will issue Certificate of Quality on our Company, It will show the original mill name and the original data.
3.Q: Once the received products found not comply with the products the contract demands, what will you do?
A: Once the received products found not comply with the products the contract lists, when receiving the pictures and the official documents and data from your side, if it is proved not comply, we will compensate the loss at first time.
4.Q: How long is your delivery time?
A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.
5.Q: Do you provide samples ?
is it free or extra ? A: Yes, we could offer the sample and do not pay the cost of freight.
6.Q: What is your terms of payment ?
A:Payment<=1000USD, 100% in advance. Payment>=1000USD, 30% T/T in advance ,balance before shipment.
