Who We Are

Baoshuo manufactures pipe repair fittings for water, gas and industrial piping systems — five product series, in carbon steel and stainless steel, with sizes from DN15 to DN4000. In-house CNC machining, welding and hydrostatic testing run under three ISO management systems.

Every product is designed around field conditions: live-line repair, branch take-offs, and permanent leak sealing. Fittings are machined in-house and hydrostatically tested at 1.5× rated pressure — up to 20 MPa on high-pressure orders — before dispatch.
