power tong test stand made in china

Texas International Oilfield Tools (TIOT) offers a free standing test stand for testing of hydraulic casing and tubing power tongs. The test stand is designed to resist torque applied by a power tong through a test mandrel.

The test stand is an air operated device that utilizes a hydraulic active dual spring disc brake chamber in order to apply friction force (“brake” action) to the rotating (or stationary) test mandrel mechanism. The power tong is tested by applying torque to the test stand’s mandrel. The test stand’s brake is activated by pushing and twisting clockwise the red control box button on the control box. A brake foot pedal is supplied as backup for the mini power unit. Using the control box mounted on the test stand, the black knob regulates pressure.

The casing power tong is used to make up and break out for casing operation in oilfields. It has greatly reduced the labor of worker, enhanced connection qualityof thread and diminished accidents. in inappropriate casing operation. Thepower tong has the following features :

Goh Chok Tong Chinese: 吴作栋; pinyin: Wú Zuòdòng; Pe̍h-ōe-jī: Gô͘ Chok-tòng; born 20 May 1941) is a Singaporean former politician who served as Prime Minister of Singapore between 1990 and 2004, and Secretary-General of the People"s Action Party between 1992 and 2004. He was the Member of Parliament (MP) for Marine Parade SMC between 1976 and 1988, and Marine Parade GRC between 1988 and 2020.

In 1985, Goh became Deputy Prime Minister and began to assume the responsibility of the government in a carefully managed leadership transition. According to Lee Kuan Yew, his preferred successor was Tony Tan. However, Goh was selected by the second generation of PAP leaders that included Tony Tan and Ong Teng Cheong; Lee accepted their decision.: 114–116 However, during the 1988 National Day Rally, Lee Kuan Yew publicly discussed his preferred choice of successor to the nation - ranking Goh as number 2 below Tony Tan, and while praising his "faster mind", criticized his indecisiveness and softer and consultative approach to leadership. This led to Goh feeling humiliated and flabbergasted, as he reflects on this incident in his memoirs, Tall Order: The Goh Chok Tong Story.

On 28 November 1990, Goh succeeded Lee Kuan Yew and became the second Prime Minister of Singapore. During the first year of Goh"s premiership, Lee remained as secretary-general of the PAP.Cabinet, holding the post of Senior Minister. The 1991 general elections, the first electoral test for Goh, led to the party winning 61% of the popular vote which is the all-time low for PAP since independence. Because of the drop in share of the popular vote, and losing an unprecedented four seats in Parliament to the opposition, Goh has to quell rumours about his potential resignation to the international news media. In 1992, Lee handed over the post of Secretary-General of the People"s Action Party (PAP) to Goh, successfully completing the leadership transition.

Goh"s Deputy Prime Ministers: Lee Hsien Loong and Ong Teng Cheong was both diagnosed with cancer in 1992, which prompted the prime minister to call an by-election in his own constituency of Marine Parade in 1992, just over 1 year after the 1991 General Elections, citing the need for "political self-renewal" and to get "ministerial calibre" people to join the government. Teo Chee Hean, who is currently one of the core leaders of the 3G members of PAP and Senior Minister, was one of the new politicians brought in to contest in the by-election.

Goh"s administration whose access to Bill Clinton"s White House was blocked because of the Michael Fay incident did not deter Goh from reaching out to the US President to pitch his idea for a free trade agreement (FTA) between Singapore and the US, as he did not believe Clinton to be aware of the diplomatic freeze. With the help of American businessman Joe Ford, Goh managed to reached out to President Clinton during the 1997 APEC summit, where he played Golf with the President, ending the diplomatic freeze. On September 1998, Goh had a meeting with President Clinton in the White House and agreed to contribute to the Korean Peninsula Energy Development Organization (KEDO) which helped build strong ties between the two countries. The considerable improvement in this bilateral relationship had great impact on Singapore"s economic recovery from the Asian Financial Crisis as several trade negotiations, part of "The Millennium Round" have failed (1999 Seattle WTO protests and Doha Round) have broken down. As international trade was three times Singapore"s GDP at that time, securing trade treaties was paramount to Singapore"s economic survival, with the US as its most desired trading partner. By riding on the improved relationship with the Clinton"s administration, Goh personally reached out to President Clinton during the annual summit at Brunei in November 2000, near the end of Clinton"s second term of his presidency. After a midnight golf session with Clinton after the banquet, Goh successfully convinced Clinton on a Singapore-USA FTA, with Clinton suggesting a FTA similar to the US-Jordan FTA. The FTA with USA was eventually signed in 2003 and this was USA first FTA with an Asian country, with Goh exalting this FTA as the "crown jewel" of Singapore"s international trade.

In the 2006 general election, Goh was tasked to help the PAP win back the two opposition wards of Hougang and Potong Pasir.Low Thia Khiang and Chiam See Tong retained their respective wards.

In 2018, Goh"s first volume authorised biography book titled Tall Order: The Goh Chok Tong Story was published. It details Goh"s life from his childhood to until he took office as Singapore"s second prime minister in 1990.

On 4 August 2019, Goh made a Facebook post stating that he felt saddened by how his long-time friend, former PAP politician Tan Cheng Bock, had "lost his way" by forming a new political party, Progress Singapore Party (PSP), to contest in the next general election.

A second volume of his biography titled Standing Tall: The Goh Chok Tong Years was released in April 2021 to mark his 80th birthday. The sequel consists of the 14 years which Goh was the Prime Minister of Singapore.

We present observations for 20-MA wire-array z pinches of an extended wire ablation period of 57%{+-}3% of the stagnation time of the array and non-thin-shell implosion trajectories. These experiments were performed with 20-mm-diam wire arrays used for the double-z-pinch inertial confinement fusion experiments [M. E. Cuneo et al., Phys. Rev. Lett. 88, 215004 (2002)] on the Z accelerator [R. B. Spielman et al., Phys. Plasmas 5, 2105 (1998)]. This array has the smallest wire-wire gaps typically used at 20 MA (209 {mu}m). The extended ablation period for this array indicates that two-dimensional (r-z) thin-shell implosion models that implicitly assume wiremore »ablation and wire-to-wire merger into a shell on a rapid time scale compared to wire acceleration are fundamentally incorrect or incomplete for high-wire-number, massive (>2 mg/cm), single, tungsten wire arrays. In contrast to earlier work where the wire array accelerated from its initial position at {approx}80% of the stagnation time, our results show that very late acceleration is not a universal aspect of wire array implosions. We also varied the ablation period between 46%{+-}2% and 71%{+-}3% of the stagnation time, for the first time, by scaling the array diameter between 40 mm (at a wire-wire gap of 524 {mu}m) and 12 mm (at a wire-wire gap of 209 {mu}m), at a constant stagnation time of 100{+-}6 ns. The deviation of the wire-array trajectory from that of a thin shell scales inversely with the ablation rate per unit mass: f{sub m}{proportional_to}[dm{sub ablate}/dt]/m{sub array}. The convergence ratio of the effective position of the current at peak x-ray power is {approx}3.6{+-}0.6:1, much less than the {>=}10:1 typically inferred from x-ray pinhole camera measurements of the brightest emitting regions on axis, at peak x-ray power. The trailing mass at the array edge early in the implosion appears to produce wings on the pinch mass profile at stagnation that reduces the rate of compression of the pinch. The observation of precursor pinch formation, trailing mass, and trailing current indicates that all the mass and current do not assemble simultaneously on axis. Precursor and trailing implosions appear to impact the efficiency of the conversion of current (driver energy) to x rays. An instability with the character of an m=0 sausage grows rapidly on axis at stagnation, during the rise time of pinch power. Just after peak power, a mild m=1 kink instability of the pinch occurs which is correlated with the higher compression ratio of the pinch after peak power and the decrease of the power pulse. Understanding these three-dimensional, discrete-wire implosion characteristics is critical in order to efficiently scale wire arrays to higher currents and powers for fusion applications.« less

Chinese leadership statements and military writings make clear China probably understands that strategy, and the military has invested heavily in defending Party leaders.

“We have long sought a dialogue with China to enhance our understanding of our respective nuclear policies, doctrine, and capabilities; to improve transparency; and to help manage the risks of miscalculation and misperception,” the review says. “We hope that China will share this interest and that meaningful dialogue can commence.”

Thus, excessive secrecy remains a hallmark of China’s approach to deterrence. By keeping its nuclear and non-nuclear military power secret, China calculates the United States will not risk a conflict without fully knowing what kind of weapons will be used.

Because China is developing new and formidable capabilities to threaten U.S. interests and those of allies and partners, the Pentagon is expanding the conditions for using nuclear forces in response to non-nuclear attacks, such as the destruction of satellites or devastating cyber attacks on power grids.

China’s Defense Ministry reacted to the nuclear review with harsh criticism. Spokesman Ren Guoqiang, repeating standard Beijing propaganda, saying the review’s view of China as a threat was a reflection of American anti-communism.

“We hope the US side will discard its ‘cold-war mentality,’ shoulder its own special and primary responsibility for nuclear disarmament, understand correctly China’s strategic intentions and take a fair view on China’s national defense and military development,” he said.
