China’s raw coal output to decline to 3.6 billion mt in 2016

Amid the overall sluggishness seen in China’s coal industry, increasing losses are expected to be incurred by more coal enterprises in China. It is expected that China’s raw coal output will total 3.758 billion mt in 2015, down three percent year on year, according to a new report issued by Chinese news research portal. The report in question states that China’s raw coal output is expected to decrease to 3.6 billion mt in 2016, down 4.2 percent year on year.

China's coal sector has been hit hard by sluggish demand caused by slowing industrial activity, stronger hydropower output and the government's battle against pollution. The coal industry has helped strike a balance between the country's energy supply and demand, marking a good start to the social and economic development, said Xiao Yuanping, Sales Manager of the Seko Machinery & Technology Co.,Ltd(www.gdsko.com, The main products are SS pipe making machine and Decorative Tube Mill).” It was noted that greater efforts should be made to maintain a balance between supply and demand, ensure a stable coal market, and properly control coal consumption.”

How to understand the size of the pipe(2)?

There are two common methods for designating pipe outside diameter (OD). The North American method is called NPS ("Nominal Pipe Size") and is based on inches (also frequently referred to as NB ("Nominal Bore")). The European version is called DN ("Diametre Nominal" / "Nominal Diameter") and is based on millimetres. Designating the outside diameter allows pipes of the same size to be fit together no matter what the wall thickness.

1.For pipe sizes less than NPS 14 inch (DN 350), both methods give a nominal value for the OD that is rounded off and is not the same as the actual OD. For example, NPS 2 inch and DN 50 are the same pipe, but the actual OD is 2.375 inches or 60.33 millimetres. The only way to obtain the actual OD is to look it up in a reference table.

2.For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is equivalent to DN 350.

Since the outside diameter is fixed for a given pipe size, the inside diameter will vary depending on the wall thickness of the pipe. For example, 2" Schedule 80 pipe has thicker walls and therefore a smaller inside diameter than 2" Schedule 40 pipe.

How to understand the size of the pipe(1)?

Pipe sizes can be confusing because the terminology may relate to historical dimensions. For example, a half-inch iron pipe does not have any dimension that is a half inch. Initially, a half inch pipe did have an inner diameter of 0.5 inches (13 mm)—but it also had thick walls. As technology improved, thinner walls became possible, but the outside diameter stayed the same so it could mate with existing older pipe, increasing the inner diameter beyond half an inch. The history of copper pipe is similar. In the 1930s, the pipe was designated by its internal diameter and a 1⁄16-inch (1.6 mm) wall thickness. Consequently, a 1-inch (25 mm) copper pipe had a 1 1⁄8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings. The wall thickness on modern copper is usually thinner than 1⁄16 inch (1.6 mm), so the internal diameter is only "nominal" rather than a controlling dimension. Newer pipe technologies sometimes adopted a sizing system as its own. PVC pipe uses the Nominal Pipe Size.

Pipe sizes are specified by a number of national and international standards, including API 5L, ANSI/ASME B36.10M and B36.19M in the US, BS 1600 and BS EN 10255 in the United Kingdom and Europe.

US ITC to expedite sunset reviews standard, line, and pressure pipe from China

The US International Trade Commission (ITC) announced Monday that it has voted to expedite its five-year (sunset) reviews concerning the antidumping and countervailing duty orders on certain seamless carbon and alloy steel standard, line, and pressure pipe from China(Also is lucky, not INOX pipe making machine). As a result of this vote, the Commission will conduct expedited reviews to determine whether revocation of these orders would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time. All six Commissioners concluded that the domestic group response for these reviews was adequate and the respondent group responses were inadequate and voted for expedited reviews.

The Seko Machinery Co.,Ltd’s sales manager Miss Lucy said，this is a bad news to China welded pipe industry, shows that barriers to trade has become more serious in the United States.

Product: INOX pipe making machine、Decorative tube making machine、Polishing Machine、Roll Set

Typically metallic piping is made of steel or iron, such as unfinished, black (lacquer) steel, carbon steel, stainless steel or galvanized steel, brass, and ductile iron. Iron based piping is subject to corrosion in highly oxygenated water stream.[2] Aluminum pipe or tubing may be utilized where iron is incompatible with the service fluid or where weight is a concern; aluminum is also used for heat transfer tubing such as in refrigerant systems. Copper tubing is popular for domestic water (potable) plumbing systems; copper may be used where heat transfer is desirable (i.e. radiators or heat exchangers). Inconel, chrome moly, and titanium steel alloys are used in high temperature and pressure piping in process and power facilities. When specifying alloys for new processes,the known issues of creep and sensitization effect must be taken into account. Seko Machinery specializing in the production of Metal pipe making machine（Including the INOX Tube Mill, HF Tube Mill, Decorative Tube Mill and so on）for many years.

Lead piping is still found in old domestic and other water distribution systems, but it is no longer permitted for new potable water piping installations due to its toxicity. Many building codes now require that lead piping in residential or institutional installations be replaced with non-toxic piping or that the tubes' interiors be treated with phosphoric acid. According to a senior researcher and lead expert with the Canadian Environmental Law Association, "...there is no safe level of lead [for human exposure]".

SEKO Machinery's Purchasing department

SEKO Machinery execute standards of ISO9001 international quality management system to the letter, its products are exported to Dubai, Russia, India, Thailand, Pakistan, Vietnam, Serbia, Kazakhstan and so on.

Companies have made so great achievement, because the company every employee in the hard work. Especially the purchasing department staff, they are very hard. They just press forward and do the best they can, ” The SEKO Machinery’s manager Mr Xiao Yuanping has said.

Procurement is a very important work, mainly due to:

1, purchasing material costs accounted for the proportion of total production cost is very big. If the material or equipment cannot be obtained at a reasonable price, directly affect the enterprise management.

2, purchasing high turnover rate, can improve the efficiency of the use of funds. Reasonable purchase quantity and the appropriate purchase time, can avoid stock outs for production workshop, and can reduce material inventory, reduce the backlog of funds.

3, when purchasing department can gather market intelligence, provide new material to replace the old material, to improve quality, reduce the cost.

4, the purchasing department to deal with the market, often can understand market trends, to feedback the market information to company executives, accelerate the development of company business performance.

Just because of their hard work, SEKO‘s product(Decorative pipe making machine, HF Tube Mills,INOX pipe making Equipment) would sell so well. Thank you for your efforts to the company.
