PRODUCT DETAILS
Description
Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.
Seamless Pipe (and tubing) is made by extruding a steel block or by drilling a solid steel bar. Next, the extrusion or the drilled steel bar is cold drawn through a dye to achieve the diameter and thickness needed. Because this process can cause mechanical hardening, sometimes the material is annealed and straightened as a final process.
Seamless Pipe & Tubing is subdivided as:
Cold Drawn Seamless, or CDS, exhibits precise tolerances and a good surface finish.
Hot Finished Seamless, or HFS, has less critical tolerances and somewhat scaly finish and is not as strong as CDS.
For Drawn over Mandrel, or DOM tubing, the first stages of manufacturing are identical to ones used to make electric resistance welded tubing, but in the finishing stages the entire flash weld is taken out and the tube is cold drawn over a mandrel. A mandrel is a round object against which material can be forged or shaped. The cold drawn process provides the tube with better dimensional tolerances, improved surface finish and the strongest weld strength achievable.

Process
Seamless line pipe
For its different manufacturing process, there’re hot rolling steel tube and cold drawn seamless steel tube. Agico sells seamless line pipe available in different sizes, weights and grades, customer can choose from black line pipe and galvanized line pipe. from 2-3/8" to 24", steel grade A, B, X42 - X80.
Welded line pipe
Oil and gas welded line pipe for intra-field is used to transport crude oil and natural gas from the field to oil refineries and storage facilities, as well as to shipment points and distribution nodes.
Packing
Package of carbon steel seamless pipe
Plastic caps plugged at the two sides of pipe ends
Should be avoided by the steel strapping and transport damage
Bundled signs should be uniform and consistent
The same bundle(batch) of steel pipe should be came from the same furnace.
The steel pipe has the same furnace number, the same steel grade, the same specifications.
Packaging and delivery
The company has the Shandong Dayang Steel Pipe Production Base Warehouse Area, Dadong Steel Pipe City Boutique Goods Yard Sales Area, etc., with an annual inventory of 70,000 tons.The annual round steel trade volume is 650,000 tons, with 50,000 tons of spot goods throughout the year, and the output value is about 6 billion yuan. The factory has eight pipe expansion production lines, mainly producing 300-1500mm outer diameter, with an annual output of 80,000 tons.
Customer visit
Adhering to the tenet of "strict management, good reputation, strong strength, and high-quality service", the company serves customers and friends at home and abroad with high standards of scientific environmental protection, professional innovation, and currently exports to more than 150 countries and regions in Europe, America, South America, the Middle East, Asia, etc., and the products are well received by everyone!
Factory
The factory focuses on the research and development and manufacturing of seamless steel pipes, oil casing processing for oil fields and gas cylinder steel pipe products. It currently has one hot-rolled seamless steel pipe production line. The production process of the hot-rolled seamless steel pipe production line adopts conical perforation, precision pipe rolling and three-roller micro-tension sizing. The production specifications are: Φ50-Φ273mm, wall thickness: 4.5-40mm, and the online equipped ultrasonic flaw detection system, eddy current flaw detection system and other product detection systems have reached the industry leading level.
