Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of a350 lf2 valve ball in China. If you're going to wholesale cheap a350 lf2 valve ball made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Basic Introduction
The A350 LF2 valve ball is made from ASTM A350 LF2 low-temperature carbon steel as the billet, forged and subjected to low-temperature heat treatment. It has excellent low-temperature toughness and fatigue resistance, can maintain stable mechanical properties in extremely low-temperature environments, and avoid the risk of low-temperature brittle fracture. Its outstanding low-temperature adaptability makes it particularly suitable for reliable control scenarios in liquefied natural gas (LNG) transportation, low-temperature gas storage, and oil and gas pipelines in cold regions.
