Since the beginning of this year, the global SA573 Grade 58 structural steel bar steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global SA573 Grade 58 structural steel bar steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where SA573 Grade 58 structural steel bar high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The SA573 Grade 58 structural steel bar hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.
SA573 Grade 58 structural steel bar, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
In 2015, we participated in an tender for oil and casing pipe in Pakistan. Because of our professional service and company strength. The end user chose us as the final contractor of the project of 22000 meters pipes of different sizes production. It takes us about 3 months to produce all the pipes SA573 Grade 58 structural steel bar . We use bulk vessel to ship the pipe to Karachi port. Our engineers went to Karachi port to inspect the condition along with the customer when ship arrive. The customer gave high appraise to the pipe quality and our service
our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, SA573 Grade 58 structural steel bar good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase SA573 Grade 58 structural steel bar API 5CT N80 and so on casing pipes.
