The forged steel ball valve plays an important role in natural gas pipelines. The natural gas pipeline forged steel ball valve is a forged steel structure, which is especially suitable for working conditions such as gas, purified natural gas, sour natural gas, water, coal slurry and oil. It is suitable for Class150~Class1500, The working temperature is -28~300℃ on the pipeline of various working conditions such as petroleum, chemical industry, thermal power station, and it plays the role of cutting off or connecting the medium.
Because forged steel ball valve trim materials are also carefully selected, the wall thickness of the valve body and the connection strength of the bolts of the valve body are calculated according to the requirements of the American standard ASMEB16.34, to ensure the corresponding valve body pressure level and joint strength Reliable strength. The ball adopts a fixed structure and a floating valve seat, which can reach a small torque under operating pressure. It adopts a metal sleeve with self-lubricating PTFE, which is matched with a high-strength, high-finish valve stem to minimize the friction coefficient.
The pipeline forged steel ball valve uses polymer materials as the seat seal, and the sealing seat is spring loaded. It has excellent sealing performance in a wide range of temperature and pressure changes, ensuring a seal without bubble leakage under the action of the closing pressure difference, and The minimum operating torque can be maintained under the maximum pressure difference. The specifications and pressure ratings of the forged steel ball valve meet the requirements of the American Petroleum Institute API16D/ISO14314 standard, the Chinese GB/T19672 standard and the American ASME standard. According to customer requirements, the valve can be made of materials that meet the American Corrosion Engineering Association standards NACEMR0175 or NACEMR0103.
The design and manufacturing quality system of the ball valve is based on the ISO9001 quality system standard and the APIQ1 quality program specification, and has been recognized by the DNV Classification Society and the American API Petroleum Institute. It conforms to the ISO9001 quality system standard, conforms to the APIQ1 and API6D specifications, and is authorized Use API monogram, certificate number is API6D-0652.
The pipeline forged steel ball valve has a variety of materials to choose from, with complete specifications and pressure levels, both full venting and shrinking, and it is an ideal valve for a wide range of applications in oil, natural gas, chemical raw materials and other transportation pipelines.
