Product Description

Professional Manufacture Cheap Welded Steel Pipes

 
Steel tube are the most common pipe gas engineering in the application. Its main advantages are: high strength, good toughness, bearing stress is big, good impact resistance and rigor, plasticity is good, easy to weldingAnd hot working, with thin wall thickness, saving metal. But its corrosion resistance is bad, need to have proper corrosion protection measures. Steel pipe by high quality low carbon steel commonly used in the fuel gas projects (Q235) or low alloy steel (16 mn).

2. ASTM Seamless Steel Pipe SA10 astm a106 b grb pipe price 65mn spring steel pipe ASTM 1065 spring seamless steel pipe

stock sizes:

outer diameters: 6mm -1020mm

wall thickness: 6mm-1020mm

length : 5000mm-13000mm

other sizes need new production.

 

3. ASTM Seamless Steel Pipe SA10 astm a106 b grb pipe price 65mn spring steel pipe ASTM 1065 spring seamless steel pipepicture and weight counting method as follow:

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, the processing pictures are as follows:


Packaging & Shipping

1. by bundles, each bundle weight under 3 tons, for small outer diameter seamless steel pipe, each bundle with 4 - 8 steel strips.
2. after making by bundle, covered with Polyethylene waterproof cloth.
3. make black painting on each pipe, then make bundles the seamless steel pipes are transported to seaport

shipping by bulk vessel, so loading on bulk vessel ; also shipping by container, container loading picture also as following:
