Natural Gas

Q125 petroleum casing is a seamless steel casing used to transport liquids and gases. It is composed of multiple steel connectors and can withstand harsh environmental conditions such as high pressure, high temperature and corrosion. Therefore, it is widely used in petroleum, natural gas, chemical industry and other industries.

Weather-resistant ASTM A423 Grade 1 steel pipe, suitable for pressure-containing components such as economizers or other applications requiring corrosion resistance.

42crmo4 seamless steel pipe is a high strength, high toughness, corrosion resistant alloy structural steel, widely used in mining machinery manufacturing field.

ASTM A135 ERW steel pipe, whether grade A or B, is usually manufactured using a high-frequency resistance welding process. Welds of ERW pipe conforming to ASTM A135 Class B shall be heat treated after welding to a minimum temperature of 1000°F [540°C].
