For any product, "Technology is life, quality is guarantee", this sentence makes sense. In the field of air compressors, technology and quality are even more important. For air compressors, any problem is a big problem that has plagued the noise problem in this industry. As we all know, noise pollution is also an important factor in environmental pollution. People living near factories or roads are more or less affected by noise from mechanical equipment and automobiles. The use of noise pollution indicators as indicators for assessing factories and living environments has long been included in the index of environmental protection standards. Therefore, equipment production suppliers should also have the responsibility and obligation to use technical means to reduce noise during the operation of machinery and equipment, and better create a low-decibel working environment.
Technicians have been working on ways to reduce air compressors. The current good solution is to use mufflers, silencing tunnels, etc. to reduce the noise of the air compressor.
First of all, the main noise sources of air compressors are inlet and outlet ports, and suitable inlet and exhaust mufflers should be used in these places. The frequency spectrum of the inlet noise of the air compressor is of low frequency characteristics. The inlet muffler should use a resistance structure or an impedance composite structure with resistance and resistance. The air compressor has a large exhaust gas pressure and a high air velocity. A small hole muffler should be used at the air compressor outlet.
Next, set the air compressor muffler tunnel. An underground or semi-underground pit of an anechoic pit. The pit walls are made of sound-absorbing bricks. Connect the inlet pipe of the air compressor and the silencing tunnel so that the air enters the air compressor through the silencing tunnel. The use of anechoic tunnels can greatly reduce the intake noise of air compressors and have a longer service life than conventional mufflers.
Science is developing and technology is improving. Experts in the field of air compressors continue to work hard, and the technology to reduce air compressor noise has been improving. Of course, continuous improvement is needed.
our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
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 
Technical Delivery Condition
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.
2,Enquiry/order required information
We can give our clients once they gave us the below information
But if clients tolerance is higher than below Hokkai standards, it shall be provided to Hokkai prior to offer or ordering.
