Womic Stainless Steel Co., Ltd
Traditional pipes suffer from many inherent problems. Ordinary carbon steel pipes are prone to rusting and have a short service life; anti-corrosion coated pipes are susceptible to coating delamination, which leads to corrosion, leakage, and potential safety hazards; while fully stainless steel pipes are expensive, significantly increasing project costs.

Advanced Manufacturing Technology
Womic Stainless Steel Co., Ltd. has developed multiple mechanical cladding technologies, includinghydrostatic pressure cladding, spinning cladding, and diameter-reducing cladding, meeting the needs of DN15–DN2000 bimetallic composite pipes across different industries.
Among these, thehydrostatic pressure cladding processis particularly representative. Originating from internationally advanced technology, it was granted aChinese national invention patent in 2012.
This process uses water as the pressure-transmission medium, ensuring:
Uniform and gentle bonding
No damage to the stainless steel surface
Simultaneous hydrostatic pressure testing during production
As a result, a100% factory pass rateis ensured.
This technology successfully increased the maximum machinable diameter of stainless steel lined composite pipes from the traditional technical limit of377 mm to 1620 mm, laying a solid foundation for the widespread application of large-diameter lined composite pipes.
Womic Stainless Steel Co., Ltd. independently developed:
Stainless steel lined integrally clad elbows
Stainless steel lined integrally clad tees
Stainless steel lined integrally clad reducers
These products filled a major gap in China’s composite pipe fitting market.
Using matching composite fittings greatly improves pipeline safety and reliability, while avoiding the high cost of fully stainless steel fittings and the negative impact such fittings can have on weld strength.
From a cost perspective, bimetallic composite pipes offer significant advantages. Compared with fully stainless steel pipes,stainless steel lined composite pipes can reduce material costs by approximately 30%–50%.
For example, in multiple water-diversion pipeline projects forNongfu Spring, the use of stainless steel lined composite pipes ensured water quality requirements while substantially lowering procurement costs.
In terms of overall value, bimetallic composite pipes not only offer lower prices but also superior performance:
Eliminate rust issues common to carbon steel pipes
Avoid coating delamination problems of anti-corrosion pipes
Prevent the excessive cost of fully stainless steel pipes
Combined with Womic’s comprehensive fitting solutions and technical support, the overall cost-performance ratio is further enhanced.
