1. Company Introduction

The tube company was established in 1994 and went into production in 1996. After 10 years of development, it has been one of the biggest professional precision tube companies in China, even in Asia.

The seamless pipe production capacity of our company is 2 tons per year. product group interval is 4219mm, TH0.530mm,maximum length 19m. the product is popular used in aviation, space flight, nuclear energy, boiler, chemical engineering, fertilizer, chemical fiber, food , medicine, etc. Our company is the professional production base of seamless pipe in China.

Our company have three product lines, precision tube & San Hua tube" production line, which at 90's advanced level, is to supply high precision tube to the needs of highly advanced industry ,such as aviation, aerospace, nuclear energy, chemical, chemical fertilizer, chemical fiber, during the Eight Five-year plan. Before that, the needs of high precision tube depended on import from other country for a long time.

2. Organization of Production Providing raw tubeOur company has perfect smelt metal and drilling skill, whose technical merit is also leading position in china . As one of the largest special steel production bases, we have electric arc furnace , electroslag furnace, vacuum induced furnace, non-vacuum induced furnace, electron bombardment furnace, vacuum and high-temperature alloy, AOD and VOD finery etc. many types of melt furnace. We can manufacture many types of special steel, high temperature steel which can satisfy many kinds of requirements, we have the optimum condition of offering steel billets.

Drilling Two-roller cone mill drillingOur company have100mm two-roller cone mill machine , maximal drilling standard is 115mm, the advantages of this two-roller cone mill are high ratio of finished product and short production period. Apply to general carbon structure steel , alloy structure steel and common stainless steel.

Extrusion drillingOur company have a 3150 ton extrusion machine, that's a only of ferrous metal metallurgical industry in China. At the present time most of the overseas company (like Sandvik etc., the famous tube company) are using extrusion machine in drilling of stainless steel tube and high-temperature alloy tube. Because extrusion process makes low plasticity high alloy deformed easily, which is unmanageable .We obtained fine surface and uniformity quality of the tube billets, which is the best way of providing special steel , high-temperature, hard steel tube billets.

Adopting the advanced pilger cold rolling and trichloroethylene degreasing technology, to make sure that length of tube, high of dimensional precision and good surface quality. Tube length attainability is more then 20 meters (under specified conditions, the length can be lengthened. Solving the problems of furnace tube, heat exchanger tube cant be jointed and reducing of jointing points etc., due to the reasons of technology, safety etc.. It can meet the requirement of the length of U-pipe transporting and heating water for large boilers, preventing the problem of nonuniform quality which is caused by jointing. The precision of rolled tube is high, the size tolerance as follows: diameter 0.1mmwall thickness5%can meet the requirement of high pressure boiler tube working and technology. Tubes surface quality is good, the brightness of internal and external surface after rolling could reach 1.6um, even higher, improve the tubes foundation in high temperature, enable its high temperature creep rupture strength is higher than tubes with rough surface. We degrease HN03+HF by adopting the trichloroethylene degreasingtechnology. Traditional degreasing technology may cause the defect of superacid orpoor acid resistant-corrosive property of tube by mishandling in production. Thetrichloroethylene degreasing prevents the defect effectively and has no effect onresistant-corrosive property.

By adopting the bright heat treatment technology, H2+N2 protection or pure H2 bright heat treatment technics is adopted during medium and final production of steel tube. After heat treatment tubes outside is nonoxidation, during the working tube dont need acid cleaning, to avoid acid corrosion of finished surface, that will let resistant-corrosive down.

PolishingCombined Sand-Belt Grinding and Polishing Working Machine set imported from Germany is a advanced machine, when its polishing abrasive band and tube elastic contact that cant burn the surface, and the cutting speed and stress is uniform that ensure the quality within the standard range. By polishing, we can upgrade the surface quality and size tolerance, obtain precise size and bright surface.

Packaging Mark The companys products are used plastic pipe closure at the both ends, and adopted by the pipe jet printing technology under computer control. We put obvious signs on the whole pipe surface, and mark clear indication of steel grade, heat number, specifications, standards, manufacturers, etc., that is very convenient for customers.

Nondestructive Test Because of the high requirement of security, we adopt repeated nondestructive test to avoid defects. We have U1trsonic and Eddy-current Inspectors which can satisfy the production requirement. Meantime we imported a high precision Eddy-current & U1trsonic Inspection machine from Germany, which can test the tube from lengthways and transverse orientations, this machine has run two years normally, and ensure the quality of tube within the standard range.
