Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general forming process as the below sketches

1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in diameter.
The United Nations promotes the use of efficient lighting on a global scale
On November 10, 2014, the Global Efficient Lighting Forum was held in Beijing. UN Secretary-General Ban Ki-moon sent a video message to the forum calling for carbon emission reduction. Hosted by the United Nations Environment Programme (UNEP) and the Global Center for Efficient Lighting Technology (GELC), the conference promotes dialogue between government agencies, businesses, NGOs, technical agencies and civil society to promote efficient lighting on a global scale. Applications. Ka Wei, Executive Director of the Asia-Pacific Regional Office of the United Nations Environment Programme. According to Kaveh Zahedi, the promotion of efficient lighting is of great importance to countries that rely on fuel imports for power generation, helping to reduce electricity consumption, haze and carbon emissions, reducing electricity bills, and thus reducing the construction of thermal power plants. In recent years, many countries have formulated policies to promote efficient lighting and eliminate inefficient lighting. Relevant standards have been introduced one after another, and product testing laboratories have been established. This means that UNEP and other agencies have promoted the world in efficient lighting. The importance of efficient lighting. Efficient lighting saves money and environmental protection Zahdi pointed out that currently, lighting electricity accounts for 15% of global electricity consumption, and the carbon dioxide emissions generated by the world's 5. Advanced lighting technologies including LED and control can reduce carbon dioxide emissions by more than half. The use of efficient lighting not only helps protect the global climate and the environment, but also benefits all countries and their consumers. The reduction in the use of such lighting in Asia alone can reduce nearly 200 million tons of carbon dioxide emissions per year, equivalent to Australia. Annual carbon dioxide emissions. In addition, the economic benefits of using LED lights are not to be underestimated. Zahdi said that if commercial high-efficiency lamps and lighting equipment are widely used, the world will save more than $120 billion in electricity costs each year. China is a leader in the global lighting industry, with advanced technology for export, and efficient lighting can accelerate energy efficiency and enable China and other countries to achieve inclusive growth. The use of efficient lighting helps reduce PM2.5 emissions In recent years, smog weather has frequently appeared, seriously affecting people's lives and health. Zahdi said that the use of LED lights will indirectly reduce the emissions of PM2.5, the culprit causing haze. Thermal power stations and other heavy industries are major PM2.5 emitters and a major source of air pollution. Zahdi pointed out that if existing non-energy-saving lighting equipment is replaced by LED equipment, 280 thermal power stations will be built less. Although we have not made specific statistics at present, an LED lamp will reduce the emission of PM2.5, but the use of LED lights saves electricity costs. It can be seen that the use of efficient lighting will effectively reduce the dependence on coal-fired power generation. , thereby reducing PM2.5 emissions, helping to improve air quality. While outdoor pollution has caused widespread concern, indoor pollution has also threatened the lives of the people. According to the World Health Organization (WHO), more than 2 million people die each year from inhaling fine particles from indoor and outdoor air pollution. Zahdi said that in many households in Asia and Africa, kerosene lamps are still the main lighting equipment. Kerosene lamps not only pollute indoor air, but also cause fire hazards. By applying LED lights to indoor lighting, people can reap the benefits of safety and health. This green and sustainable lighting solution will benefit thousands of families. Experience Sharing and Technology Transfer Zahedi said that the Global Efficient Lighting Forum has created an international communication platform. Representatives from more than 60 countries around the world share their experiences in promoting efficient lighting, involving laws, policies, technologies, brands and Finance and many other aspects. In addition, the promotion of lighting energy-saving emission reduction mode will be applied to refrigerators, fans, air conditioners and other electrical appliances. The United Nations will continue to work with the government, relevant industries, technical departments and social organizations to promote energy conservation and emission reduction. In order to achieve the best results in energy saving and emission reduction, it is necessary for all parties to cooperate, because everyone plays a different and indispensable role in this project, Zahdi said. The government needs to play a more important role in policy formulation and encourage the production of energy-efficient products; companies should promote technology research and development to meet relevant standards; other technical institutions such as the Global Efficient Lighting Technology Center should be able to detect relevant standards and technologies. All of the above parties also have the same task of promoting the concept, brand and logo of efficient lighting to consumers, so that they understand and are willing to actively purchase energy-efficient products. As an ordinary consumer, when purchasing lighting equipment, you should also choose those energy-efficient products that not only save money but also protect the environment and contribute to the green earth.
