[INQ. NO. 2602M06] Since its founding in 1998, KUMKANG has specialized in manufacturing and supplying various models of water tanks and pipes to ensure a safe water supply environment in Korea.
KUMKANG established its own technology research center in 2009 and developed the spol pipe in 2011. The spol pipe received New Excellent Product (NEP) certification in 2012.

Spol Pipe, Eco-friendly Water Supply Material
Spol Pipe is an eco-friendly water supply material that has received Environmental Label (EL). Made of highly hygienic stainless steel, it prevents internal and external corrosion, permanently extending the pipe’s lifespan and enhancing resource recycling. It also does not produce harmful substances such as bisphenol-A, rust, or sludge that degrade water quality. The SP series of the pipe is a high-performance, eco-friendly water supply material that has received environmental and performance certifications from various government agencies in Korea.

Water-Supply Pipe Made of Stainless Steel
The water contact surfaces of this product are made of stainless steel, providing a hygienic and safe water supply environment, free of rust and endocrine disruptors. The exterior is coated with polyethylene to prevent soil corrosion and enhance durability.

Composite Pipe with Excellent Water Resistance and Adhesion
KB27E’s strong adhesive power and water-resistance prevents the peeling and shrinkage of the sheath part. KB27E, a proprietary stainless-steel adhesive, offers excellent bonding strength and resists water dissolution.
KB27E’s three-component formula of metal ions, acrylic acid, and VLDPE provides superior adhesion and water resistance.
The KB27E used in the pipe offers strong bonding strength and water resistance, preventing peeling and shrinkage of the sheath part.

Composite Pipe with Excellent Shrinkage Prevention
With the application of ultra-fine filler, the pipe dramatically reduces the shrinkage of the sheath part compared to conventional products. This product uses a compound that mixes ultra-fine fillers of less than 5 microns manufactured by air jet milling (magnetic crushing) into High-Density Polyethylene (HDPE).
The filler acts as crystal nucleate and increases the speed of crystallization, thus improving the dimensional stability, and preventing the shrinkage of the sheath part. The shrinkage rate is significantly reduced, to less than 1/4 that of conventional PE and less than 1/10 that of conventional PE sheath.

Earthquake-Safe Spol Pipe
The maximum stress applied to the pipe during a magnitude-7 earthquake is 18.4 MPa, which is only 9% of the pipe’s maximum allowable yield stress of 207 MPa. Performance testing by an authorized institution has confirmed the pipe’s earthquake-safety.

Stainless Square Water Tank
Made of stainless steel, it supplies clean, safe water. It offers excellent space utilization and can be further strengthened by installing internal baffle plates and stoppers. This is a KC-certified product for water supply, ensuring superior quality and hygiene.
Internal reinforcements are installed to accommodate the internal and external loads of the water tank, thus ensuring safety and durability.
Using urethane insulation, it offers lightweight, heat-insulating, and shock-absorbing properties.
“Our water tanks and pipes are made of hygienic and safe stainless-steel, ensuring clean and safe tap water, enabling people to drink it with confidence, thereby improving public health and quality of life. We will continue to manufacture reliable and safe stainless lining water tanks, and stainless composite pipes, contributing to a safer water supply environment,” the company’s CEO emphasized.
