Key features

The hydrotester applies programmable water pressure up to 100 MPa, holds set dwell time, and monitors decay. Any drop beyond tolerance automatically rejects the pipe, ensuring leak-proof and quality.

Quick-change hydraulic sealing heads fit pipe diameters from 2 to 120 inches within minutes. Rubber seals provide zero-leak clamping at high pressure, reducing downtime and boosting flexibility.

The PLC-based system logs pressure curves and test results for every pipe. It automatically marks defects and rejects failed pipes, ensuring full traceability, consistent quality control

AI-Powered supplier vetting

SummaryThe supplier manufactures industrial tube, pipe, rolling, slitting, cutting, beveling, and testing machinery. It reports professional engineering and production personnel, quality assurance processes, finished-product inspection instructions, ISO 9001:2015 and CE certification, and customization ranging from sample- and design-based work to full customization. It exports 31%–40% of sales and has self-operated import/export rights, with products reportedly sold across more than 30 provinces and cities and exported to Southeast Asia and Africa. Complaint handling and corrective/preventive-action procedures are documented and followed. However, only one quality assurance/control inspector is reported, lead time is 2–3 months in both peak and off-peak periods, and no inventory, overseas warehouse, showroom, agent, or branch capability is reported. Financial information is insufficient for a meaningful credibility assessment. SDK availability is explicitly absent, while OEM service for well-known brands is...

Supplier typeThe supplier is presented as an industrial machinery manufacturer whose product range includes spiral pipe mills, HF ERW tube mills, JCO pipe mills, seamless tube mills, slitting and cut-to-length machines, rolling mills, pipe beveling machines, and hydrostatic testers. Its reported engineering, technical, and production personnel support classification as a manufacturing supplier.

CertificationsThe supplier reports an ISO 9001:2015 management-system certificate and CE product-compliance certification. These are explicit certifications, although the provided information does not specify their scope, validity dates, or which individual products are covered.

After-Sales capabilityThe supplier describes complete pre-sale and after-sales service, and it has documented procedures and records for corrective/preventive actions and effective customer-complaint handling. It also states that technology, quality, and after-sales guarantees are based on customer interests, providing direct evidence of a structured service capability.

Production capacityThe supplier reports production personnel, a quality assurance system, advanced inspection means, standardized finished-product inspection instructions, a broad machinery product portfolio, and 2–3 month fulfillment times in both peak and off-peak seasons. Nevertheless, only one quality assurance/control inspector is reported, and no inventory, overseas warehouse, showroom, agent, or branch capability is available; the evidence supports manufacturing capability but not broad overseas service infrastructure.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also reports OEM service for well-known brands, indicating broad stated customization and OEM capability.

Client casesThe supplier reports products selling in more than 30 provinces and cities, exports to Southeast Asia and Africa, OEM service for well-known brands, and recognition through awards for supply and product quality. These statements indicate market reach and claimed customer acceptance, but no named customers, project references, or independently verifiable case details are provided.

Product Q&A

Q:What is the main purpose of a steel pipe hydrostatic tester?

It verifies the leak-tightness and structural integrity of welded or seamless steel pipes by filling them with water and applying internal pressure higher than the service rating. The test detects micro-cracks, pinholes, and weld defects that could cause failure in service. It is mandatory for International standard, and other pipeline standards. The machine automatically pressurizes, holds for a set dwell time (usually 5-15 seconds), monitors pressure drop, and records results.

Q:How does the machine seal the pipe ends without leakage?

Two main sealing methods are used: end-face (axial) sealing and radial (OD) sealing. End-face sealing uses a rubber seal pressed against the pipe's bevelled end, suitable for small to medium diameters. Radial sealing uses expandable rubber sleeves or O-rings gripping the outer surface, often applied to large-diameter pipes. Both systems are hydraulically actuated to achieve clamping forces up to several hundred tons.

Q:What test pressure and hold time are typically applied, and what if pressure drops?

The test pressure is usually 1.5 times the specified minimum yield strength (e.g., for X60, about 60-70 MPa), but may vary per customer specification. Hold time ranges from 5 to 30 seconds depending on pipe diameter and wall thickness. During the hold phase, pressure sensors monitor any drop - a permissible loss is normally within 2% of set pressure; beyond that indicates leakage or expansion. Modern machines have automatic rejection systems that mark bad pipes.
