公司简介 brief introduction

长沙湘晖企业有限公司 CHANGSHA XIANGHUI ENTREPRISE CO., LTD

CS xianghui enterprise Co.,Ltd is a group company which manufactures, cooperates and

trades the steel tubes and pipes. Our company is located at Tianxin district, Chang sha. We

invested several mills (Hunan xianghui steel pipe co.,ltd Jiangsu seamless boiler tube mill,

Anshan Xingya Steel Pipe Plant .). We are one of the biggest companies that devote to the

industry of steel tubes and pipes in south China, and specialize in producing and supplying all

kinds of specification and many kinds of Steel Pipes.

As a big modern enterprise, we do not only have all kinds of the advanced equipment but

also many excellent sales teamwork that have fruitful sales experience in domestic and

overseas market. To ensure quality, we adopt the advanced manufacture equipment and

techniques, mechanics performance test, technical performance test, eddy current flaw

detecting, corrosion tests, high precision analysis of carbon and sulfur, and a complete set of

advanced means are also performed by a group of high qualified inspection personnel. We

have exported our seamless steel pipes to many countries in the world, such as the U.S.A.,

Canada, UK, Germany, Italy, Netherlands, Belgium, Brazil, Argentina, Colombia, Chile,

Ecuador, India, Pakistan, Malaysia, Indonesia, Singapore and so on, and have obtained high

reputation and reliable credit in the those countries. Our steel pipes are widely used in many

fields such as petroleum, chemical industry, aviation, power station, energy, boiler and heat

exchanger, ship, subway, automobile, medical, ornament etc. In China market, we are

assigned as specified suppliers for CNPC, Sinopec and china-car,

We pay much attention to the building of enterprise and image, and our aim:" Quality

First, Customer above all，cooperation and win-win". We- warmly welcome clients from all

over the world.
