Bimetal Clad Pipe

Bimetal Clad Pipe and Bend are cast with mold vanishing vacuum suction casting cladding process. Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique.

Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique.

Bi metal clad pipe with high carbon content, impact resistance, low thermal expansion, pressure, high temperature, mature, complete specifications; has many manufacturers of Bi metal clad pipe is widely used in oil, chemical, power and other industrial fields , Its scope of application more and more widely, brought about by the economic, environmental and social benefits are more obvious.

Bi metal clad pipe compared to pure alloy tube cost advantage:

Bi metal clad pipe Applicable areas:

Civil areas:
Cold, hot water pipes, direct drinking water pipes, heating, solar energy, ground source heat pump; civil construction water supply pipes, water distribution trunk; air conditioning circulation pipe, fine decoration high-grade commercial housing water pipes.

Industry:
Oil and gas pipeline, oil and gas wells casing, sewage return pipe; chemical heat exchanger tube bundle; power desalination water, desulfurization pipeline and other metallurgy, desalination, medicine and chemical industry, sewage treatment, new energy, food processing and other industries.

Bimetallic connection:

Most of the outer tube is used galvanized pipe, followed by a galvanized pipe mature connection:
1, As shown in Figure 1, threaded connection (commonly known as thread connection), for DN15-DN100, the implementation of GB7306-2 and GB3287-1982 standards;
2, groove clamp connection, for more than DN100, the implementation of CJ / T156 standard;
3, flange connection, as the case may be, generally more than DN100, flange and so on by the manufacturers, and in the connection with a dedicated silicone layer;
As shown in Figure 4, welding connection, according to the actual working conditions using welding, the implementation of YB / T5092-2005 and JB / T4747-2002 standard, generally used three-layer welding, the first argon arc welding back cover, re-welding transition layer, the last manual arc Fill the filling surface.
