Three-tenths of heavy-duty tires do not meet EU minimum requirements

From November 2012, the European Union's new labeling directive 2009/1222/EC came into effect. From the perspective of the specific scope covered by the European Tire Labeling Law , almost all tires are covered, and tires that are not in compliance with the standards are forbidden to import and sell. The implementation of the labeling law is divided into three phases, namely 2012, 2015 and 2018. The implementation of the EU labelling law is both a challenge and an opportunity for the domestic tire and rubber industry. Media reporters have also conducted sample surveys on some people who have recently implemented the EU labelling legislation from rubber raw materials to tire companies, which is more convenient for the market to gain a deeper understanding of the effectiveness of EU labelling legislation.

According to Shanghai Tyre & Rubber (Group) Co., Ltd.'s investigation and analysis of national heavy-duty tires , at present, about 30% of domestic load-carrying tires still do not meet the EU's minimum requirements for rolling resistance in the first phase, and 70% do not reach the EU's second The minimum requirements for rolling resistance at the stage; and the rolling resistance of car tyres are mostly E and F grades, most of which can temporarily meet the minimum requirements of the first phase of the EU. In short, the semi-steel tire currently produced by the vast majority of domestic tire manufacturing enterprises can basically meet the requirements of the first stage of the EU Tire Labeling Act. The second stage of implementation is in 2015. Before 2015, the tire industry passed the work. Samples, sample tests to meet the European Union labeling law rolling resistance B level requirements.

Recently, Dushanzi Petrochemical dissolved polybutadiene butadiene butadiene rubber production plans increased. Its current production of 2564S is similar to that of LANXESS 5025, with a vinyl content of 64%. It can also be seen that domestic tire exporters are adjusting formulas and responding to EU labelling. The implementation of the bill. At the same time, Yanshan Petrochemical's original SBS production line plans to produce solution-polymerized styrene-butadiene rubber in 2013, Liaoning Dainasuo Synthetic Rubber Co., Ltd. plans to put into operation a solution-polymerized styrene-butadiene rubber project in the first half of 2013. The technology of this project is derived from the Danaxo elastomer. the company. South Korea's Kumho Petrochemical and LG Chemicals have plans to further expand their existing solvent-based SBR plants. Sumitomo Chemical's SSBR project in Singapore will also be launched on the market in 2013, and its domestic offices have begun to plan the operation of pre-production promotion. It can be seen that, in 2013, domestic and foreign merchant SSBR product promotion and sales will be fully opened. In domestic SSBR devices, everyone has the highest expectation value for Liaoning Panjin Daisasso. According to the market-based polybutadiene-butadiene rubber agent, the current downstream tire factory's procurement of polybutadiene-butadiene-styrene rubber is cautious, and the actual SSBR sales of agents have not been significantly increased due to the implementation of the first stage of the tire labeling act. At present, tires and other product companies have increased the production cost of SBR, and the price of finished tires exported to foreign countries has not risen as a result, said a sales agent for polybutylene-butadiene rubber.

What is even more fortunate is that China's tire labeling system is also being established. China's tire labeling method is being jointly developed with various tire companies. It is expected that the first draft of the tire labeling method will be completed by the end of 2012 and may be promulgated in April or May 2013. The development of green tires is an inevitable trend. It is believed that with the help of relevant domestic associations, the promotion and application speed of domestic SSBR products will increase. Therefore, in the short term, the tire industry is still facing structural adjustments and technological renewal. In the area of ​​R&D, raw material costs, and equipment, investment should be increased to accommodate future updates of the EU and other countries' labeling legislation; short-term profitability can also be reduced gradually. In exchange for a long-term profit increase in total capacity.

CASING

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place

The oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the whole well during drilling and after well completion. Several layers of casing shall be used for each well according to different drilling depth and geological conditions. Cement shall be used for cementing after casing is put into the well. It is different from TUBING and drill pipe and cannot be reused. It is a disposable consumable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.

Surface casing

- Protects the well from contamination in shallow water and gas layers.

- Supports the wellhead equipment and sustains the weight of the other layers of casing.

Intermediate casing

- Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.

- Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.

Production casing (oil string)

- It is the conduit through which oil and gas pass from a below surface reservoir.

- It protects the well and separates fluids into various layers.

First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The threading type includes STC/BTC/LTC. The casing pipes are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.

Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm.
