Iron ore inventory edges up at Chinese ports

As of December 14, inventory of iron ore at 33 major Chinese ports amounted to 88.06 million mt, up 1.49 million mt or 1.7 percent compared to the inventory level recorded on December 7, as announced by China’s Xinhua News Agency on December 15. As of the same date, the Xinhua-China Iron Ore Price Index for imported iron ore with 62 percent iron content was at 38 points, down two points week on week. Meanwhile, the Xinhua-China Iron Ore Price Index for imported iron ore with 58 percent iron content was at 34 points on the date in question, also down two points week on week. In the given week, imported iron ore prices in China continued to indicate an overall declining trend as most traders were selling off iron ore in the spot market. Currently, with sluggishness prevailing in China’s domestic finished steel market and environmental policies being implemented in northern China given smoggy weather conditions, most steel enterprises have reduced production in Shanxi Province. It is thought that imported iron ore prices in China will likely fluctuate within a limited range in the coming period.

The Arab customer to visit SEKO Machinery Company

On December 5, SEKO Mechanical received a letter of Arab customer, confirmed that they will be visiting on December 9, in order to look at the machine and discuss details about the purchasing Stainless Steel Pipe Making Machine. Before customer come, we did a lot of preparation work.

After the customer get to the company, we took him to visit our two factories and meeting rooms, took him to see our machines, and the welded pipe that our machine do manufacture.

This Arab customer ery pleased with our, is willing to cooperate with us.

The construction and operation of pipeline transport

Oil pipelines are made from steel or plastic tubes with inner diameter typically from 4 to 48 inches (100 to 1,220 mm). Most pipelines are typically buried at a depth of about 3 to 6 feet (0.91 to 1.83 m). To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high-density polyethylene, imported sand padding, and padding machines.

Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go-devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig-launcher stations and travel through the pipeline to be received at any other station down-stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line.

For natural gas, pipelines are constructed of carbon steel and vary in size from 2 to 60 inches (51 to 1,524 mm) in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority.

The setup and equipment of annealing

Typically, large ovens are used for the annealing process. The inside of the oven is large enough to place the workpiece in a position to receive maximum exposure to the circulating heated air. For high volume process annealing, gas fired conveyor furnaces are often used. For large workpieces or high quantity parts, car-bottom furnaces are used so workers can easily move the parts in and out. Once the annealing process is successfully completed, workpieces are sometimes left in the oven so the parts cool in a controllable way. While some workpieces are left in the oven to cool in a controlled fashion, other materials and alloys are removed from the oven. Once removed from the oven, the workpieces are often quickly cooled off in a process known as quench hardening. Typical methods of quench hardening materials involve media such as air, water, oil, or salt. Salt is used as a medium for quenching usually in the form of brine (salt water). Brine provides faster cooling rates than water. This is because when an object is quenched in water air bubbles form on the surface of the object reducing the surface area the water is in contact with. The salt in the brine reduces the formation of air bubbles on the object's surface, meaning there is a larger surface area of the object in contact with the water, providing faster cooling rates. Quench hardening is generally applicable to some ferrous alloys, but not copper alloys.

The safety issues of the welding

Welding can be dangerous and unhealthy if the proper precautions are not taken. However, using new technology and proper protection greatly reduces risks of injury and death associated with welding. Since many common welding procedures involve an open electric arc or flame, the risk of burns and fire is significant; this is why it is classified as a hot work process. To prevent injury, welders wear personal protective equipment in the form of heavy leather gloves and protective long sleeve jackets to avoid exposure to extreme heat and flames. Additionally, the brightness of the weld area leads to a condition called arc eye or flash burns in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. Goggles and welding helmets with dark UV-filtering face plates are worn to prevent this exposure. Since the 2000s, some helmets have included a face plate which instantly darkens upon exposure to the intense UV light. To protect bystanders, the welding area is often surrounded with translucent welding curtains. These curtains, made of a polyvinyl chloride plastic film, shield people outside the welding area from the UV light of the electric arc, but can not replace the filter glass used in helmets.

Welders are often exposed to dangerous gases and particulate matter. But the SEKO Machinery company of welder series are very safe. For example, SEKO Tig Welding Machine, SEKO Plasma Welder, Plasma and Tig intergrated Welder and so on, they have been installed device to protect operators.

How many common shielding gases？

Shielding gases fall into two categories—inert or semi-inert. Only two of the noble gases, helium and argon, are cost effective enough to be used in welding. These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Pure argon and helium are used only for some nonferrous metals. Semi-inert shielding gases, or active shield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. Most of these gases, in large quantities, would damage the weld, but when used in small, controlled quantities, can improve weld characteristics.
