PRODUCT CENTER
DIN 1629 seamless steel pipe its main grades are St37.0, St44.0, St52.0, DIN 1629. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.
EN 10219/S235 Welded Steel Pipe
EN 10219 standard is used to produce pipes, and cold-formed steel pipes EN 10219 S235JR are very suitable for welded structures.
Spiral Submerged Arc Welded Pipe SSAW
The spiral submerged arc welded pipe is made of hot-rolled steel strip as raw material, and is usually made by constant temperature spiral forming and automatic submerged arc welding. The manufacturing process is to roll the steel strip, make the rolling direction at a certain angle to the center direction of the tube, and then form and weld, so the weld is spiral. Can provide API SPEC 5L steel pipe, GB / T3091,GB / T9711-2011,EN10219,ASTM A252 standard steel pipe.
The longitudinal submerged arc welded pipe is made of steel plate as raw material, which is formed by a forming machine, and then double-sided submerged arc welding is carried out. Through this process, the LSAW pipe will have excellent ductility, toughness, uniformity, plasticity and good sealing performance. The production equipment can be produced quickly, easy to replace, and the product specification range of LSAW pipe is large. The production line can produce welded pipe diameter 406-4500mm, wall thickness 8mm-100mm.
Resistance welded pipe ERW is formed by hot rolled coil through forming machine. The skin effect and proximity effect of the high frequency current are used to heat and melt the edges of the tube blank. Pressure welding is carried out under the action of squeeze rollers. Realize production. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the equipment is few, but the general strength is lower than that of seamless steel pipes.
Galvanized pipe Galvanized steel pipe, also known as galvanized pipe, is divided into two kinds of hot dip galvanized and electro galvanized. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long. Zinc is commonly used to galvanize or coat these metal tubes. The galvanizing process for steel pipes involves immersing the metal pipe in a bath containing 450 degrees Fahrenheit molten zinc. After a few minutes, the hot-dip galvanizing process is complete.
ASTM A656 steel coil is a high-strength low-alloy steel used in structural applications. In structural applications, light weight and good formability are essential. ASME A656 steel plates are manufactured in different grades of 50, 60, 70 and 80 steel coils with specified yield points.
A709/S355J0W Carbon Steel Coil
ASTM A709 steel coil is in accordance with the standard specification for bridge structural steel, ASTM A709 steel coil is a carbon, high strength low alloy and quenched and tempered alloy steel mainly used in bridge construction. BBN offers the following 5 grades of steel coils: A709,36, 50, 50W, HPS 50W. The atmospheric corrosion resistance index of 50W, HPS 50W and HPS 70W are 6.0.
GB/T700 GB/T1591 GB Material Carbon Steel Coil
GB/T700 Q275 carbon steel and low alloy steel coil equivalent material is S275JR steel plate. S275JR steel coil is a general purpose carbon structural steel. This steel is similar to the steels listed in China GB/T700 and GB/T1591. It is also a carbon structural steel and low alloy structural steel used in engineering steel and structural steel, which is usually not heat treated. GB/T1591 steel coil is a Chinese standardized low alloy medium tensile strength steel coil produced by hot rolling process. GB/T1591 steel coil has a variety of manufacturing purposes.
EN10025-2 S235/S275/S355 Carbon Steel Coil
EN10025-2 steel coil is a low-alloy high-strength structural steel, which is made of carbon structural steel (Wc = 0.16%~ 0.2%) by adding a small amount of alloying elements. EN10025-2 steel coil has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature.
DIN 17100 ST37/ST52 Carbon Steel Coil
DIN 17100 steel coils are suitable for flange beams, steel bars, steel strips, steel plates, wide flat steel, seamless steel pipes and welded steel pipes, square and rectangular hollow profiles. According to standards, DIN 17100 steel plates are used for welding, riveting and threaded structural parts. Except for stress relief heat treatment and normalizing, it is not used for heat treatment.
JIS G3101 SS400/SS490/SS540 Carbon Steel Coil
JIS G3101 SS400 is a common carbon structural steel grade. Other grades of JIS G3101 are ss330, ss490 and ss540. Relevant product types include steel coils, steel plates, steel sections, and steel pipes.
