Chinese company Saihua broke the global monopoly of globe valve
Small-diameter high-temperature and high-pressure globe valves, one of which is only 12.5 cm high and 6 cm wide, have to withstand high temperatures above 650 degrees Celsius and a pressure equivalent to 320 kg. The technical requirements are extremely stringent. The international market has always been firmly controlled by the United States, Germany and other countries, and even the Chinese market, almost all rely on imports. It is accidental and inevitable that Saihua instrumentation can squeeze into the international market from the "door seam."
At the end of last year, a power plant project in India held a tender meeting for small-diameter high-temperature and high-pressure globe valves in Shanghai. The bidders were all top-ranking manufacturers in the small-diameter high-temperature and high-pressure globe valve market in the United States and Germany, and the Chinese companies connected the venue. The door cannot enter. On that day, the director of Saihua Instrument and Control Song Jianzhong knocked on the door of the conference room and handed out a bid from the cracks to the staff. He only asked the other party to take a look. Unexpectedly, this material immediately attracted the keen interest of Indian merchants. The same high-quality materials were used in the world-class brand names, and the price was only one-half that of foreign products.
Indian merchants immediately decided to send a person to Saihua Instrumentation to test the product on site. The technical staff of Indian merchants came to Saihua Instrument and Control and through strict inspection, they were amazed at the quality of the company's small-diameter high-temperature high-pressure globe valve. Then, Saihua Instrument and Control invited France’s most authoritative company to conduct third-party testing of its products. "The test is extremely strict." Song Jianzhong told reporters that only the second single 12 million yuan product costs 200,000 yuan for testing.
The first-rate quality, together with the "replaceable core seal" device created by Saihua Instrument Control's original small valve, allowed Indian merchants to abandon the most well-known companies in the world and chose Saihua Instrument and Control. In the most evaporable valve tube under high temperature and high pressure gas, Saihua Instrument added a replaceable seal, and once the core seal is damaged, it only needs to be replaced. Because in the case of high temperature and high pressure, an additional seal is placed inside the valve conduit with a small diameter and the technical requirements are extremely demanding. The US, German, and other national manufacturers once set the technology as a “forbidden zone,†and no one dares to involve it. After 10 years of R&D, Saihua IAC finally broke this restricted area, successfully developed products with independent intellectual property rights and obtained invention patents.
Since 1994, Song Jianzhong and his team have been targeting the high-end valve market and are eager to push Chinese brands onto the international stage. After introducing the original technology of a small-diameter high-temperature and high-pressure globe valve from the United States, Saihua began a decade of hard research and development. "Foreign brands generally have a one-year product warranty period. Now, Saihua dares to propose a warranty of eight years. This shows that the quality of our products is not lower than the world's top products." Song Jianzhong said with confidence.
Although there is technology and quality, the process of entering the market is not smooth. The application of small-diameter high-temperature and high-pressure globe valves is extremely wide. Power plants, aviation, nuclear submarines, etc., are used wherever there is an engine. According to estimates, at present, the Chinese market has a demand of 20 billion yuan for this product. “But the domestic manufacturers basically only believe the products of the United States, Germany and other countries, the successful entry of Saihua Instrumentation into the international market, but also let everyone see the strength of our national industry.†Song Jianzhong's goal is to make the world-class small-caliber high temperature High-pressure shut-off valve manufacturers let Chinese and global manufacturers believe that they are made in China.

Boiler Steam header is the main supporting equipment of the boiler to distribute the steam generated by the boiler operation to various pipelines, it also serves as a reservoir that feeds steam to the individual heating circuits. The boiler steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit.
Steam header belongs to the category of pressure vessel, its pressure capacity, volume should be corresponding to the supporting boiler. The main compression elements are head, housing, etc.
