NST to showcase zero-leakage pipeline systems at FLOWTECH CHINA

NST will present its dismantling joints and zero-leakage pipeline systems at FLOWTECH CHINA in Shanghai, aiming to address joint stress, thermal expansion and micro-leakage in municipal and industrial water networks. The company is using the exhibition to highlight pressure ratings, manufacturing controls and lifecycle cost savings for critical infrastructure operators.

Why it matters: - Municipal water systems, pumping stations and valve vaults face losses from micro-leakage, thermal expansion and ground settlement. - NST is positioning its dismantling joints as a way to reduce installation time, limit pipe stress and protect critical equipment. - The company is tying the product pitch to long-term infrastructure reliability and lower non-revenue water losses.

What happened: - Newstar Valve (Zhengzhou) Co., Ltd., also known as NST, is set to demonstrate dismantling joints and zero-leakage pipeline systems at FLOWTECH CHINA in Shanghai. - The company says technical representatives will show tension adjustment and seal integrity under pressure testing at the exhibition. - NST is presenting the products as part of a broader push for municipal and industrial fluid control applications.

The details: - A dismantling joint is a bidirectional telescopic fitting used to install and remove valves, pumps and meter assemblies in rigid piping networks. - The joints provide longitudinal adjustment of up to tens of millimeters, which helps align flanges without stressing adjacent pipe sections. - NST says the main body is made from high-tensile ductile iron or fabricated carbon steel and machined with CNC equipment for tight concentricity. - High-strength steel tie rods distribute end-thrust forces across the flange connection instead of transferring stress to nearby concrete structures or pump casings. - The sealing system uses an elastomeric gasket profile made from EPDM or NBR for potable water and industrial effluent service. - Under bolted compression, the follower ring compresses the seal into a precision-machined chamber, and internal line pressure increases the sealing effect. - The company says the joints can withstand operating pressures up to PN16, PN25 or PN40. - NST says its production process includes electric induction furnaces, automatic molding lines, multi-axis CNC machining, shot blasting to Sa 2.5 standards and electrostatically applied fusion-bonded epoxy coatings over 250 microns thick. - Each production batch undergoes hydrostatic body testing, seat tightness verification, ultrasonic wall thickness measurement and coating pinhole detection. - NST says its products conform to ISO 2531, EN 545, BS EN 1092-2 and ANSI/AWWA C219. - The company says it holds more than 40% market share for butterfly valves in municipal water treatment. - NST says customized dismantling joints can be adapted to different pressure ratings, lay-lengths and environmental conditions, including seawater desalination plants and deep underground trunk lines. - Engineering teams support projects from hydraulic modeling through installation oversight and help specify dimensions, flange drillings and protective linings. - More information is available on the company's website: the official corporate website.

Between the lines: - NST is using the trade show to frame dismantling joints as a reliability and cost-control tool, not just a pipe accessory. - The focus on sealing performance, material choices and quality testing signals an effort to appeal to municipal buyers with long asset-life requirements. - The company is also leaning on manufacturing depth and standards compliance to differentiate itself in a crowded infrastructure market.

What's next: - NST plans to meet engineers, contractors and municipal planners at FLOWTECH CHINA. - The company is offering technical submittals and custom CAD drawings for upcoming projects. - The exhibition should give NST a sales platform for new municipal water treatment and pipeline upgrade work.

The bottom line: - NST is betting that zero-leakage performance, pressure durability and easier maintenance will win attention from infrastructure buyers looking to cut lifecycle costs and water loss.
