Lined Bends with 304L Liner

1. Introduction
Bimetal lined pipe consists of one base pipe and one liner pipe. Carbon steel pipe is generally used as the base pipe, which is responsible to withstand the outside pressure. And the liner pipe is produced by using the corrosion-resistant alloy of stainless steel, titanium alloy, copper, aluminum, etc. The characteristic is that the layer between pipes is combined closely, and these two metal pipes will be bending simultaneously if they were impacted by outside force. Xi'an Sunward always manufactures bimetal clad or lined pipes as what the standard requires. Xi'an Sunward strictly executes the standards of testing and inspection of API 5LD and DNV-OS-F101, and we own complete test and inspection machines which can cover 100% of the stipulated items of inspections.



Bimetal lined pipe is a safe, mature and economic product, and it possesses technical and economic advantages compared with carbon steel pipe and CRA pipe. As the majority of the oil or gas fields that are to be developed have a large number of corrosive elements, the corrosion-resistance property of the steel material can be decisive for this issue. Carbon steel pipe can be one option, but corrosion problems and the maintenance cost in the future can be unimaginably high. Meanwhile, CRA pipe is several times more expensive than the lined pipe, and most of the field owners reject to use it for considering the huge cost. Thus, CRA lined pipe can solve each of the problems. By using the carbon steel as the base pipe, the total cost of the lined pipe can be controlled to a certain lower level, and the liner pipe can sufficiently guarantee the corrosion-resistance property. 

2. Specification
Xi'an Sunward Aeromat Co., Ltd. can provide full series of lined pipes with different material combination (the following table illustrates possible selections that are covered by our factory). As to the dimension, Xi'an Sunward has tremendous experiences on manufacturing lined pipes with outside diameter from 1'' to 48''. At the same time, the bimetal lined pipes manufactured by Aeromat have been successfully applied in various environments, for instance, inland, desert, underwater, subsea, etc. Table 1 briefly introduces the products with different materials, which can be provided by Xi'an Sunward Aeromat Co., Ltd.
   3. Why Us
A. Familiar with Relevant International Standards
Xi'an Sunward Aeromat, as the first company that is approved by API 5LD, also the first company that involves in petroleum and gas industry by providing bimetal clad or lined pipes on the sea, can fully comprehend two international standards of API 5LD and DNV-OS-F101 for bimetal clad or lined pipes. The company is familiar with the construction of welding for lined pipes and related NDT standards as well, which can benefit the product manufacturing and after-sales service.
 
B. Own Complete Manufacturing, Test and Inspection Facilities
After the development on manufacturing over ten years, Xi'an Sunward has already possessed all the test and inspection facilities as what API 5LD and DNV-OS-F101 require, and the testing or inspecting items can cover 100% of the requirements of the standards mentioned above.
 
C. Abundant Experiences on Manufacturing CRA Clad or Lined Pipes for Petroleum and Gas industries
Aeromat has provided almost 3,000Km bimetal pipes with different specifications and materials to CNPC, CNOOC, SINOPEC Group for the use of transporting gas or oil. The company owns strong ability at after-sales service and professional devices with high precision, strong operability and portability for after-sales.


4. Company Profile
Xi'an Sunward Aeromat Co., Ltd. is a high-tech company, which relies on engine technology of solid rocket and gathers the advanced technology of aerospace science for civil use. Composite material, high molecular material and so on are the main products of the company with registered capital of RMB 90 million and total asset about RMB 430 million. Lined steel pipe plant, which is affiliated to Xi'an Sunward, is a professional manufacturing plant that utilizes the method of deflagration and hydraulic lining technology to produce high pressure-resistant bimetallic clad or lined pipe and is the only Chinese manufacturing company that is successful in providing clad or lined pipes for the pipeline construction of gas field development. 



After 10 year's development and usage of the products, Xi'an Sunward can manufacture bimetal clad or lined pipes and related pipe fittings with different specifications; owns a number of advanced technologies with proprietary intellectual property rights; and is always at the leading position among relevant sectors. The company has already been certified by ISO9001, ISO14001 and OHSAS18000, and in 2006 it became the first company in China, globally the eleventh company that has been authenticated by API SPEC 5LD and been re-authenticated in 2009.
 
Sincerely looking forward to your inquiry!
