Shijin provides integrated plumbing system solutions, is a national high-tech enterprise, a key technology enterprise of the National Torch Program, and a professional manufacturer of plumbing products.
 
It is also a leader in the plumbing industry, Weixing focuses on plumbing pipes, while Shijin focuses on valve products, and Shijin's products are all plumbing-related, which is more single in business than Weixing. Shijin began to produce copper products such as water control valves in 1989, and did not begin to get involved in pipe production until 2006.
 
Shijin's overseas business development is relatively good, the products have expanded to the United States, Canada, Japan and other more than 30 developed countries and regions, has developed into one of the largest domestic copper pipe fittings and valve export production bases, which is not unrelated to Shijin actively obtain international product certification, the introduction of the European Union CE, the United States UL and other advanced product assurance system, the products can not only smoothly enter the foreign market, but also can endorse the quality of Shijin products, enhance the sales of the domestic market, and achieve the effect of killing two birds with one stone.
 
There are many models of Shijin products, there are five models of water collectors, except for C118 is made of brass, the rest are brass nickel plated, and most of the products are different in appearance, and the internal performance is similar. As a valve company, the pressure performance of Shijin's manifold is better, and the maximum pressure is more than 30% higher than that of Danfoss and Ruihao manifolds, but in terms of daily use of floor heating systems, Danfoss and Ruihao manifolds are enough to withstand pressure, and the greater pressure-bearing performance is not practical.
 
Sejin floor heating pipes are available in PE-RT and PE-Xb, and unlike other brands, Sejin not only has oxygen-blocking and non-oxygen-blocking pipes, but also aluminum-plastic composite pipes with an aluminum layer in the middle. Due to the addition of a metal layer, the aluminum-plastic composite pipe has superior oxygen resistance, and the metal in the aluminum-plastic pipe can also help dissipate heat, and the thermal conductivity is 50% higher than that of ordinary plastic pipes, but the price of aluminum-plastic composite pipes is more expensive than that of pure plastic pipes, and the laying cost is higher.
