Pressure vessel heads, Forgings parts for pressure vessel ,Tube Plate

Pressure vessel is designed to work under certain pressure, temperature and medium for a long time, So in addition to the high requirements on mechanical properties of vessels material ,it has also set standards upon pressure vessels creep strength temper embrittlement,corrision resistance, as well as their performance under high/low temperature according to diffirent applications and environments. Strict inspection like utrasonic flaw detection, grain size ,debris test, and other metallographic examinations are required for the raw material ,requiring the steel to be of high purity,uniformity ,and contain little debirs or gas .
 
Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmaion and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rasied in the product line ,We will contact and disscuss with our clients directly.
 
Specifications

1. Apart from the required chemical elements ,we have strictly tested some harmful elements such as P S Pb Sn As Sb and Bi, as well as some gas or non-metallic debris like H O and N in the smelting process.
2. Double vacuum smelting and Etitroslag resmelting techniques are employed for pressure vessels with special requirement to ensure high purity, uniform element , and low gas content of raw material.
3. Strict forging technique is required to meet the nondestructive testing requirement.
4. We have given the pressure vessel frogings heat treatment to acquire high creep strength,little temper embrittlement, high corrosion resistance, uniform structure,high grain sizes, as well as great performance under standard/low/high temperature.
5. The finishing line is equipped with advanced CNC equipment to ensure high precision of our forgings
6. The ultrasonic flaw detection is conducted in line with the standards upon pressure vessel.

7. All of production steps such as smelting,forging,heat treatment,flaw detection,and machining are strictly controlled and inspected in TongYu, The pressure vessel we have produced comply with the national standards and European standards, such as JB/T***6, JB/T***7,NB/T****8,and ASME standards.

1. Registration certificate of steel forgings for Pressure Vessel.

2. Mo certifacate from ASME
