Long service life of ERW steel pipe

　　Q: What would we care about except the quality of ERW steel pipe?

　　A: Long service life would be an important factor for a kind of ERW steel pipe when it applied in engineering project as this means saving money to fix it and change it.

　　Steel pipe, used in water, oil and gas transportation, is necessary to have a relative long life service. As there are advantages for long service life: first of all, we should know that it would cost human resource as well as cost if we have to change it often. What’s more, it would influence the basic usage for customers if we change it often which would damage the whole process for customers sometimes.


　　Plastic or wood pipes would not so strong for the cars’ weight when we use them underground. So that steel pipe, with its hardness, is the top choice for this situation. Of course, because of the external corrosion and internal abrasion. The service life of steel pipes would be increased by the usage of proper coating and cathodic protection. With attention to coatings and cathodic protection, the service life of steel pipe can be extended indefinitely.

SMLS steel pipe for Tanzania Gas pipeline project

图片
Project location: Tanzania Product：SMLS steel pipe Specification：168.3mm*14.27mm*SDR Standard and material：API 5L X52N PSL2 Application: Gas pipeline project In the last week of September, we received a new inquiry from regular customer who stated that it would take 4 weeks for delivery, including anti-corrosion. We learned that the fast delivery is most important point for this order. Xinyue people responded the fastest. Due to this order is for X52N PSL2 G high-grade seamless pipes, the stock quantity cannot meet the quantity of the entire order. With the strong resource integration ability of Xinyue, we found the production schedule of the steel pipe factory within 3 days and quickly organized new production. The customer arranges full process supervision from end customers, contractor customers, intermediate customers, and third parties from raw materials to the factory. During the supervision process of steel pipe production, they all witness the online UT test, Hydrostatic test, ...

Treatment method of steel pipe welding slag inclusion

What is welding slag inclusion? Welded pipe slag inclusions are slag that remains inside the weld. Welding slag inclusions are generally divided into two categories: The first category is metal slag inclusions. The second category is non-metallic slag, which refers to the slag remaining in the weld after welding, including electrode coating or flux, sulfide, oxide and nitride. According to its formation, it can be divided into point-like slag inclusions, linear slag inclusions, chain-like slag inclusions and dense slag inclusions. Slag inclusions will reduce the plasticity and toughness of steel pipe welds, and slag inclusions with sharp corners will cause stress concentration at the tip, and the tip will develop into a crack source, especially in welds with a large tendency to air quenching. Under the action of stress on the steel pipe, cracks will first appear at the slag inclusions in the weld and develop along the way, resulting in a decrease in strength and cracking of the weld. T...

ERW Steel Pipe Deliver to Argentina for oil and gas pipeline

图片
Project location：Argentina Product：ERW Steel Pipe Standard and material：API 5L PSL2 46th GR.X60M Specifications： OD: 457.2mm WT: 9.52mm Lenght:12M Application：oil and gas pipeline In the steel industry, customer demands vary, but quality and delivery time are always the most critical factors. Recently, Xinyue successfully provided a high-quality ERW pipe solution for a customer, and the entire process took only half a month, perfectly demonstrating our ability to respond quickly and execute efficiently. Although the customer’s order quantity was small, the steel grade requirements for the pipes were very high, and the supplier had to be listed in the client’s approved supplier directory. Facing such strict requirements, Xinyue mobilized all available resources and actively engaged with major suppliers. Ultimately, we successfully sourced BaoSteel’s inventory, which perfectly met the steel grade and quality requirements, and ensured on-time delivery. From receiving the inquiry to finali...
