1. Hot rolled seamless steel pipe

using hot rolled steel pipe billet to make heating and piercing, elongating, sizing and stranghtening, cooling, finally hollow bars finished, this is the type most commonly used. Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small quantity, have to make cold drawn or round bar piercing. size: outer diameter 32mm- 499mm, wall thickness 4mm- 80mm

2. Cold drawn seamless steel pipe

for outer diameter not over than 63.5mm, small size hollow bar, when demanded quantity is under 5 tons, usually make cold drawn hollow bar, using larger size hot rolled hollow bar to draw to the size me size can be finished only by one time drawing, but some other sizes might need twice or three times to finish drawing, it takes time, so the cost is higher. cold drawn size outer diameter 16mm- 63.5mm

3. Hot- expanding seamless steel pipe

For hollow bar sizes are special, not common sizes, have to use smaller thick wall hollow bar to hot expand to be larger size hollow bar, but the technical property for hot-expanded hollow bar will be lower than the original hollow bar. Size: outer diameter over 356mm.

Packing

Loading

1.20 feet container: when the pipe length within 5.8 meters, will arrange shipping by 20 feet container, load 25 ton/per container. 2.40 feet container: when the pipe length within 11.5 meters, will shipping by 40 feet containers, load 25 tons/per container. 3.Bulk Vessel: when the pipe length over 11.5 meters, and quantity is big, will shipping by Bulk Vessel, the freight is cheap in this way.

We can cut the seamless steel pipe into the length you demand, and can make the surface to be bright by milling and grinding at the Lathe, and can grind the outer diameter and wall thickness to be the dimension you demand.If the sizes are not available from the standard common stock sizes, and the quantity are not enough for the new production, then we need process the stock larger seamless pipes into the sizes you need. And we also can make steel pipes deep processing. For example, size OD250x ID200 is not stock common size, then need using larger pipe to process into 250x 200, same as OD170xID100
