Stainless steel pipe is a hollow steel pipe that is not easy to rust. Stainless steel pipe is a kind of hollow long cylindrical steel. Its scope of application is used as a pipeline for conveying fluids. It is mainly widely used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc., as well as mechanical structural components. According to the manufacturing method, it is divided into two types: hot rolling and cold rolling,the thickness range is 0.3-80 mm. Cold rolling is a steel coil obtained by further thinning the No. 1 steel sheet to a target thickness under room temperature conditions. Compared with hotrolled steel, cold-rolled steel has a more precise thickness, smooth and beautiful surface, and also has various superior mechanicall properties, especially in terms of processability. Because cold-rolled raw coils are relatively brittle and hard, and are not suitable forl processing, cold-rolled steel sheets are usually required to be annealed, pickled and surface smoothed before being delivered to customers.
FAQ:
Q1: How do you guarantee the quality? A1:We have passed ISO9001, SGS, CE and other certifications; 2.Always have pre-production samples before mass production,and always do finalinspection before shipment; 3. Acceptable third-party inspection.
Q2:About the product price?
A2:Due to the cyclical changes in raw material prices, prices vary from period to period. You can consult us, you can communicate with us online through the platform, WeChat, WhatsApp and other platforms, and we will reply within 24 hours. Please give us your requirements and specifications (steel grade, size, quantity, destination port), and we will work out the best price at the first time.
Q3:Can I tour your company’s factory? A3:Of course. We welcome customers from all over the world to visit our factory.
Q4:Can you send samples? A4: Of course, we can send samples to all over the world, our samples are free, but customers need to bear the express cost.
Q5:How long is your delivery time? A5: Generally speaking, our delivery time is within 15-45 days, if the demand is particularly large or there are special circumstances, the delivery time may be delayed.
Q6:What are the packaging methods for steel products?
A6:Our steel products are usually packed by bundling. For some steel products with special requirements, such as stainless steel plates, we also use moisture – proof and anti – rust packaging materials, such as plastic films and anti – rust paper, to prevent the steel from being damaged and corroded during transportation and storage.
Q7:What payment methods do you accept? A7: We usually accept payment methods such as Telegraphic Transfer (T/T), Letter of Credit (L/C), and Collection (D/P, D/A). Of course, we can also negotiate more flexible payment methods according to specific circumstances.
