On By Sunny SteelIn Tech& ServiceLeave a comment

The weld joint quality of bimetal composite pipe directly affects the corrosion resistance and service life of pipeline. Sunny Steel has the first-class welding team and welding equipment. By virtue of rich experience in welding metal composite materials, Sunny Steel  can offer reliable site welding service.

assembly_on_site

Key points of welding :
According to structure and material, proper bevel type shall be selected.

Welding method: It is recommended to use TIG (argon tungsten-arc welding)
+SMAW (shielded metal arc welding)

According to the chemical composition of CRA alloy, welding material for root
and intermediate layer shall be selected，welding material with constant strength
shall be selected in accordance with base material.

According to the principle of “step brazing”, firstly, CRA layer shall be welded;
secondly, the intermediate layer shall be welded; lastly, the base layer shall be
filled in.

Pipe fitting: According to the material combination of bimetal composite pipe,
proper CRA pipe fitting shall be selected，it shall be welded in accordance
with technological procedure.

SunnySteel’s ceramic lined pipes resists abrasion and avoids product attrition.It reduces considerable degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.

Wear Resistant Pipe and Elbow for Pneumatic Conveying

Tubes and bends in pneumatic conveying lines are suffering more or less abrasion. SunnySteel’s ceramic lined pipes resists abrasion and avoids product attrition.It reduces considerabley degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.The compact design reduces cost of pipe support and installation. It is automatically self-purging with little pressure drop.

Ceramic Lined Elbows and Bends could be also applied in the parts of concrete pump owing to their advantages especially the low weight which helps to avoid the jam during the transport of concrete.

Features of Alumina Ceramic:

Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance.
A high density, diamond like hardness,fine grain structure and superior mechanical strength are the unique properties that make it the material of choice for a wide range of demanding applications.Ceramic has uses similar to Cast Basalt but it has greater resistance to wear in high velocity applications and impact resistance in extreme dynamic systems.

Due to the above properties of Alumina Ceramic,Ceramic Lined Pipe Elbows have the following superiorities.

Low friction factor of Ceramic at low impingement angles decreases the abrasion of materials maximally.
Ceramic-lined composite steel pipe can take place of expensive stainless steel, nickel, cast stone or alloy pipes.
And extended service life can also reduce maintenance cost.
Preventing operation cease caused by frequent replacement of pipes and elbows .
Excellent thermal resistance and abrasion resistance by ceramic material processing.
Distinguished adhesive strength by high-temperature bonding agent.
10~20 times longer life span than products processed with SS, etc.
No substance intermixed by abrasion during transportation.
Low density makes the wear resistant pipe elbow easy to carry and install.

Bimetal composite pipe

On By Sunny SteelIn Multiple composite pipeLeave a comment

Compared with corrosion-resistant alloy pipe, bimetal composite pipe has higher strength.

1.  Good Abrasion Resistance：
Compared with common steel pipe with internal anti-corrosion coating, bimetal composite pipe has better abrasion resistance.
2. Good Heat Resistance：
Compared with FRP/GRP pipe, bimetal composite pipe has better heat resistance.
3. Cost Effective ：
Low-cost base pipe, fewer CRA layer or lining pipe and optimal design of wall thickness make bimetal composite pipe cost effective.
4. Safety & Reliability：
The patented technology, special equipment and manufacturing process are used to guarantee surface quality of bimetal composite pipe and corrosion resistance of welding seam, ensure safe and reliable operation.
5. Lower Operating Costs：
Bimetal composite pipe can remarkably reduce maintenance and management expenses during the operation.

Wear-resistant alloy composite pipe Features
A good overall performance
    Composite pipe outer wall with steel , lined with high-chromium alloy , the two formed a good metallurgical bond , both high alloy materials for wear and corrosion resistance properties, but also high mechanical strength and less high impact resistance , to solve a single material can be difficult to reconcile the contradictions and abrasion resistance welding , the material play to the best level of performance advantages, the use of safe and reliable.
2 high wear resistance
    The composite wear layer composite pipe of high -chromium alloy , containing about 45% of the organization of the hard carbide M7C3 type , since this structure Ka rod- type carbide , and it has a high toughness ; while Ka macrohardness carbide micro- hardness is high (HV1500-1800), in the wear layer above HRC55 , so good wear resistance .
3 corrosion resistance , high temperature performance
    Since the composition and structural characteristics Ka carbide substrate and the Cr content of the solid solution has a strong heat resistance, corrosion resistance , high temperature or corrosive environment can show good corrosion resistance, wear resistance.
4 advanced, stable composite technology
    The wear-resistant pipe and elbow by LFC vacuum casting composite manufacturing process, namely F casting method , with the manufacturing process of composite wear-resistant pipe has the following characteristics :
    ( 1 ) The process is simple , easy to operate production yield.
    ( 2 ) Since the process is characterized by high precision tooling size , using an inner tube lined with real high vacuum in the tube by suction casting , so the product , the precise size , density is good.
    ( 3 ) using the method of vacuum casting process F resistant alloy composite pipe production and elbow, homogeneous and stable performance. Does not appear , cracks holes and other phenomena .
5 , good thermal shock performance
    Since the inner tube composite wear , thermal expansion coefficient of the outer layer equivalent to a high level and constantly changing rapidly changing conditions occasions inner fragmentation does not occur , the phenomenon of early failure occurred small pipe system running resistance, beautiful appearance beauty .
6 . Transportation, installation and ease of use
    Alloy composite pipe and elbow quick connector or flange can be welded directly mounted . As the fight against high- performance composite pipe , the pipe diversion occurs when a partial plugging free to percussion , arbitrary cutting , unloading change , installation , maintenance is very convenient.
alloy composite wear-resistant pipe applications
 1 , power plants and coal transportation systems, dry ash conveying pipe ;
 2 , Stone Coal power plant systems ;
 3 , the other a powder pneumatic conveying systems ;
 4 , hydraulic transmission systems and larger particle size slag slurry transportation ;
 5, other mining material handling .
