Products

Titanium Alloys Tube

Different from chemical pure titanium, industrial pure titanium contains oxygen, nitrogen, carbon and other elements, making its corresponding strength improved. 

Grade1, Grade2 and Grade3 refer to industrial pure titanium. The difference between the two is that the larger the number is, the impurities in the gap increase, and therefore the strength and hardness are higher. Grade7 is titanium-palladium alloy, Grade16 is titanium -palladium alloy with higher purity, and Grade12 is titanium-molybdenum-Nickel alloy. Titanium alloys have good mechanical and punching properties and can be welded by various forms of welding procedures. The strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium has high corrosion resistance to chloride, sulfide and ammonia and has better corrosion resistance than aluminum, stainless steel and nickel alloy for seawater service.

Super Austenitic Stainless Steel Pipe/Tube

Super austenitic stainless steel is defined as Cr-Ni stainless steel with a Pitting Resistance Equivalent Number (PREN=[Cr]+3.3[Mo]+16[N])≥40%. Super austenitic stainless steel is mainly developed to solve the deficiency of pitting corrosion resistance, crack corrosion resistance and poor thermal stability of the original high molybdenum (>4%) Cr-Ni austenitic stainless steel under the harsh corrosion conditions containing Cl-.

Austenitic Stainless Steel Pipe/Tube

Austenitic stainless steel has austenite as its primary phase at both elevated and room temperature. A stable austenite contains about 18% Cr, 8%-10% Ni and about 0.1% C. Cr-Ni austenitic stainless steel includes the most familiar stainless steel 18Cr -8Ni and the series of high Cr-Ni steel developed by increasing Cr and Ni content and adding elements such as Mo, Cu, Si, Nb, Ti, etc. Austenitic stainless steel is characterized by non-magnetic, high plasticity and ductility but lower strength. It can be only strengthened via cold working (by adding S, Ca, Se, Te and etc., austenitic stainless steel can have excellent machinability).

(Super) Duplex Stainless Steel Pipe/Tube

Duplex stainless steel (DSS) is featured with structure of two phases (α and γ) and has characteristics of both ferritic and austenitic stainless steel. It has best corrosion resistance and high strength. In general, when the content of C is low, the content of Cr and Ni ranges from 18% to 28% and 3% to 10% respectively. Some steels also contain the alloy elements such as Mo, Cu, Nb, Ti and N, etc.

Corrosion & High Temperature Resistant Alloys Pipe

Good stress resistance, pitting corrosion resistance, crevice corrosion resistance and local corrosion resistance at room temperature

Bimetal Composite Pipe

Composite materials have become the development trend of various industries in the world due to their comprehensive compatibility of different material and outstanding performance and economic performance. Because of the perfect combination of corrosion-resistant alloy layer function and pressure resistance function of carbon steel base, as well as the cost advantage compared with stainless steel and nickel alloy pure metal pipes, bimetal composite pipe has been widely used in the oil and gas transmission pipeline of high-temperature, high-pressure and high-corrosion environment (hydrogen sulfide, chloride ion) .

In order to meet the requirements of different working conditions, ZJJL's composite pipes are produced by two processes, that is mechanical composite and metallurgical composite, providing a comprehensive and systematic overall pipeline solution for oil and gas gathering and transportation.

(Ultra Pure) Ferritic Stainless Steel Pipe/Tube

Ferritic stainless steel is an interstitial solid solution of carbon dissolved in α-Fe with a body-centered cubic structure. It is one of the three kinds of stainless steels that came into being at the beginning of the 20th century, together with martensite and austenitic stainless steels. The traditional ferrite stainless steels contain almost no nickel, with relatively low cost and price, and excellent comprehensive performance, which make them favored by the market.
