Backpack wear resistance ceramic elbow with flange

Six performance summary of the composite pipe of the ceramic composite pipe 1, good wear resistance Ceramic composite pipe with inner liner for ceramic corundum (a-AL2 (subscript) O3 (subscript, similarly hereinafter), Mohs hardness can reach 9.0 rather than hrc90. Therefore, the grinding medium of all industries are highly resistant to wear. The industrial operation confirmed: its wear life is ten times the quenching steel or even dozens of times. 2, running resistance: Ceramic composite pipe due to the smooth surface of the inner surface is better than any metal pipe, water resistance coefficient of 0.0193, slightly lower than the seamless tube. 3, corrosion resistance, anti fouling: Since the ceramic layer is (a-AL2O3), it is a neutral material. Therefore has the acid alkali and water resistance, and at the same time with anti - scale and so on. 4, heat resistance and heat shock resistance performance is good: As the corundum ceramic (a-AL2 (subscript) O3 (subscript)) is a single st

Sleeve Type Expansion Joints

Sleeve Type Expansion Joints are primarily designed to compensate for thermal expansion but it is not the only movement being imposed on the pipeline system. Other types of movements can occur that need to be taken into account when providing a pipework flexibility solution such as building settlement, wind loading, vibration from rotating and reciprocating machinery. Related  Ceramic lined pipe Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique. The sleeve type expansion joint is also called tube compensator, pipe expansion joints, which is used for hot fluid pipelines, mainly applied to the laying of straight pipelines. And the working medium can be hot water, steam, oil, etc. The sleeve expansion joint does thermal expansion by sliding its external sleeve. Sleeve compensator Types of Sleeve Type Expansion Joint: Buried sleeve expansion joint: Using advanced sealing structure and sealing materials with the features of easy installation&

High-chromium alloy Bi-metal pipe elbows

We are manufacturer of High-chromium alloy Bi-metal pipe elbows and supply high quality High-chromium alloy Bi-metal pipe elbows in both large and small quantities worldwide and offer you the best prices in the market. These Steel-High-chromium alloy Bi-metal pipe elbows is a new type of abrasion proof piping developed by our company. Outer of straight pipe is common steel pepe, cladding realized by forming high chromium lining via centrifugal forming technique.

Bimetal Cladding Steel Pipe

Bi-metal Cladding Steel Pipe Bi-metal 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. 1. Manufacturing Process of Bimetal Clad Pipe and Bend: 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 bend uses hot-bending bend and lining is cast with high-chromium cast iron. Bends and other profile sections can be cladded in whole and this process has changed the traditional practice to fabricate bend and other profile sections by drawing polyline without changing flow pattern of material inside piping,greatly reducing conveyance resistance of material. 2. Advantages Compared with Traditional Wear Resistant Alloy Cast Iron, Alloy Cast Steel, G
