武汉长河节能环保高科技有限公司（丽景科技有限公司）注册于武汉市东湖新技术开发区，以整合人才、科技、产品、市场为己任，打破人才的区域、部门限制，拥有一批国家级的高科技人才，其中有工程院院士、国家重点实验室博导、高科技院校教授。公司奉行科技创新，以研、产、销于一体的模式开拓经营。

本公司拥有多项换热管专利技术，如多向扰流强化换热管、螺旋换热管、波纹螺旋换热管、多头螺纹换热管等，本公司开发的新一代换热管——多向扰流强化换热管具有高效 、抗振、抗结垢、抗腐蚀的特点，多向扰流强化换热管彻底解决了以往困扰业界的难题——为增强换热而减小壁厚或采用在管壁滚压螺旋线而产生的管子刚度的削弱，使得减小壁厚-增强换热-增加刚度得到完美统一 ，同时具有抗振、抗结垢的特点。

Wuhan Long River Energy &Enironment Hi-Tech Co.,LTD( formerly known as Neegeen Hi-Tech Co., LTD), registered in Wuhan East Lake High-Tech Development Zone, undertakes the mission of integrating talents, technologies, products and markets, by breaking the restraint on talents imposed by units and district, owns a lot of state class hi-tech talents, such as members of Engineering Institute, doctor tutors from national key laboratory, professors of universities. NHTC pursuits technological innovations, carrying out an innovative operation by means of integating research, manufacturing and marketing.

NHTC masters several patented technologies on heat exchange tubing, such as NEOGEN TUBE, Helix Tube, Corrugated Tube, Multi-helix Tube, etc. NEOGEN TUBE, a innovative type of tube for heat exchange, possesses the property of high efficiency, anti-corrosion, anti-fouling and anti-vibration. This new type of tube resolves the problem haunting in the professional field for long time: tube strength decreases when wall thickness decreases and grooves adopted. The solution harmonizes the three counteractive factors: WALL THICKNESS, HEAT TRANSFER COEFFICIENT, and RIGIDITY；meanwhile, it has the property of anti-vibration and anti-fouling.
