API 5L Oil and Gas Pipeline Pipe
API 5L seamless steel pipe is pipeline steel seamless steel pipe -- API 5L pipeline steel seamless steel pipe, seamless steel pipe steel quality: GR.B, X42, X46, 52, X56, X60, X65, X70. Pipeline pipes are used to transport oil, steam and water extracted from the ground to oil and natural gas industry enterprises through pipeline pipes. Pipeline pipes include seamless pipes and welded steel pipes, and the pipe ends have flat ends, threaded ends and socket ends; The connection mode is welding, collar connection, socket connection, etc. The API 5L oil and gas pipeline exported by SHANDONG HUITONG STEEL CO., LTD. fully complies with the relevant national standards, and can produce and provide products including Gr.B, X52, X60, X70 and other models. Our products have also been exported to the Middle East, Africa, South Asia, Central Asia and other countries and regions, and won wide acclaim. API 5L line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. PSL is the short name of product standard level. The product standard level of line pipe have PSL1 and PSL2, also we could say the quality standard divided in PSL1 and PSL2. PSL2 is higher than PSL1, not only the inspection standard is different, also the chemical property, mechanical strength standards are different. So when place the order for the API 5L line pipe, there should be stated clearly for the size, grades these general specification, also have to clarify the production standard leve, PSL1 or PSL2. PSL2 is more strictly than PSL1 on the chemical properties, tensile strength, non-destructive test, and impact test. API 5L PSL1 steel line pipe not required to do the impact test. For API 5L PSL2 steel line pipe, except Grade X80, all the other grades of API 5L line pipe required the impact test at temperature of 0℃. The average value of Akv: longitudinal direction≥41J, tranverse direction≥27J. For API 5L Grade X80 PSL2 line pipe, at 0℃ for all the size, impact test the Akv average value: longitudinal direction≥101J, tranverse direction≥68J. For API 5L PSL2 line pipe shall perform the hydraulic test for each single pipe, and in the API standard specification not permit to have Non-destructive test replace the hydraulic test, this also is a big difference between Chinese standard and API 5L standard. For PSL1 not required Non-destructive test, for PSL2 shall do the Non-destructive test for each single pipe. Chemical composition and mechanical strength is also different between API 5L PSL1 line pipe and API 5L PSL2 line pipe. For the detailed specification as below. API 5L PSL2 have restrictions with the carbon equivalent content, where for the carbon mass fraction greater than 0.12%, and equal or less than 0.12%. Different CEQ shall be applied. For line pipe in PSL2 tensile strength have maximum limits.

The market is not enthusiastic about ordering, Steel mill output may continue to decline
By the end of the year, coupled with the impact of the sudden drop in temperatures across the country, many construction sites have stopped work in advance for holidays. At the same time, starting from this week, traders have gradually entered a holiday state. This shows that both terminal pre-holiday replenishment and traders' "winter storage" have come to an end. Judging from the results of recent surveys in many places, due to factors such as the current relatively high price and the relatively sufficient supply of goods in the market, both terminals and traders are not very willing to stock up before the holiday this year. Traders, in particular, have become more cautious after experiencing continuous losses in [winter storage" in recent years, and their willingness to actively [winter storage" is low. Even with passive "winter storage", steel plant contract households in some areas have only completed the minimum amount agreed upon. Judging from the overall market performance, there is not much enthusiasm for ordering this year. Affected by poor market ordering conditions, high costs and shrinking profits, steel mills' production enthusiasm has been significantly weakened. According to incomplete statistics, more than 20 steel mills have announced maintenance information, and the maintenance time ranges from 30 to 45 days. According to platform monitoring data, on January 18, 75 steel plants and a total of 115 blast furnaces among the 201 production companies in the country stopped production, of which 72 and 112 were under maintenance. The average daily output of molten iron was 2.1798 million tons, a month-on-month decrease of 2.69%. Thousands of tons. At present, steel plant shutdowns continue to increase, and overall output is showing a downward trend. At the same time, steel mills` demand for coke and iron ore procurement has not increased significantly, and their enthusiasm for stocking up before the holiday is not high. There is still a certain amount of time before the Spring Festival. At present, the coke inventory of steel plants is maintained at 5-7 days. Starting next week, steel plants will carry out a certain amount of replenishment, but the overall amount will not be too large. This is mainly due to the current low season for finished product consumption and the low overall profitability of steel mills. So far, steel mills have not made any large-scale replenishment of iron ore before the holidays, and have mainly replenished iron ore in small quantities on demand. The reason is related to high raw material prices, increasing losses of steel mills, resulting in increased production shutdowns and reduced daily consumption. The current inventory of iron ore in steel plants remains at about 31 days. The inventory has changed little in the past three weeks and there is no sign of a significant increase. To sum up, due to factors such as low market enthusiasm for ordering, high raw material costs, shrinking profits of steel mills, the overall enthusiasm for steel mill production has been significantly affected, and it is expected that pre-holiday output will continue to remain relatively low. As the growth rate of output continues to slow down, it will help ease the market supply and demand situation and will provide certain support for steel prices.

The use and production process of seamless carbon steel pipe
Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to the production method, the seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking and so on. According to the section shape, the seamless steel pipe is divided into two kinds of round and shaped, shaped pipe has square, oval, triangle, hexagonal, melon seed, star, fin tube and many complex shapes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick wall seamless steel pipes and thin wall seamless steel pipes. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe,carbon steel boiler tube, bearing pipe and high-precision structural steel pipe for automobiles, tractors and aviation. Seamless steel pipe production process: ① Main production process of hot rolled seamless steel pipe: Preparation and inspection △→ Heating → perforating → Rolling → reheating → Sizing → Heat treatment △→ Straightening → Finishing → Inspection △ (non-destructive, physical and chemical, table inspection) → storage ② Cold rolled (drawn) seamless steel pipe main production process: Blank preparation → pickling lubrication → Cold rolling (drawing) → Heat treatment → straightening → finishing → inspection The use of seamless steel pipe: 1, the general purpose seamless steel pipe is rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, the maximum output, mainly used as a pipeline or structural parts for transporting fluids. 2, according to different uses divided into three types of supply: A. Supply according to chemical composition and mechanical properties; b, according to mechanical performance supply; c, according to water pressure test supply. Steel pipes supplied according to class a and b, such as those used to withstand liquid pressure, should also be hydraulically tested. 3, the special purpose of seamless pipe with boiler seamless pipe, chemical power, geological seamless pipe and petroleum seamless pipe and so on.
