FAQ

Our facility is equipped with 5,000-ton hydraulic forging presses, heavy-duty CNC machining centers, and automated beveling machines. We manufacture pipe fittings and flanges ranging from 1/2" to 80" (DN15–DN2000) with wall thicknesses up to SCH 160 / XXS.

Yes. We conduct complete in-house testing, including Hydrostatic Testing, Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), and Positive Material Identification (PMI) to ensure zero-defect delivery.

Depending on the product and specification, manufacturing may involve forming or forging, machining, heat treatment and dimensional finishing, followed by inspection and testing. Production methods are selected according to the product type, material grade, required dimensions and applicable specification to maintain consistent quality throughout the order.

For repeat and project-based orders, production requirements should be confirmed before manufacturing, including product specifications, material grades, dimensional requirements, inspection criteria and marking requirements. Maintaining consistent production and inspection procedures helps ensure that repeat batches remain aligned with the approved specification.

Pre-shipment inspection can be arranged according to the agreed purchase specification and inspection requirements. Depending on the project, inspection may include dimensional and visual checks, document review, material verification and other specified testing requirements. Customer-appointed or independent inspection can also be considered when required by the purchase order.

Yes. Custom fabrication requirements can be reviewed based on customer drawings, specifications or technical requirements. Before production, key parameters such as dimensions, material grade, wall thickness, pressure class, connection type, applicable standard and inspection requirements should be confirmed to ensure that the finished product matches the approved requirements.

Custom and non-standard piping components can be reviewed based on the required application and technical specification. For custom products, customers are encouraged to provide a drawing, dimensional requirements or an existing sample. Our team can then evaluate the manufacturing requirements, material availability, machining requirements and inspection criteria before quotation.

For an accurate quotation, customers should provide the product type, nominal size, pressure class or PN rating, material grade, applicable standard, connection or facing type, wall thickness or pipe schedule where applicable, quantity, drawing requirements and inspection or certification requirements. Delivery destination and required delivery date are also helpful for export orders.

Flange selection depends on factors such as pipe size, pressure class, connection method, operating conditions, accessibility for maintenance and project standards. Weld neck, slip-on, socket weld, threaded, lap joint, integral and blind flanges are designed for different installation and service requirements. The applicable engineering specification should always be checked before selection.

Product requirements can be reviewed against the applicable international or project-specific standard. Depending on the product, commonly requested specifications may include ASME, ASTM, EN and other recognized standards. Customers should specify the exact standard, edition where required, dimensions, material and pressure rating in the inquiry so that compatibility can be confirmed before production.

Custom fabrication typically begins with requirement and drawing review, followed by material confirmation, manufacturing planning, production, dimensional inspection and final quality review. For projects involving non-standard dimensions or special requirements, the approved drawing and technical specification should be treated as the basis for production and inspection.

Baishuo supplies industrial piping components for international projects and export markets. Export requirements may vary by destination, project specification and applicable regulations, so product standards, documentation, packaging and shipping requirements are confirmed before shipment.

Export documentation can be prepared according to the purchase order and destination requirements. Depending on the project, documentation may include commercial invoices, packing lists, bills of lading, certificates of origin, material certificates, inspection reports and certificates of conformity where applicable.

Packaging should be selected according to product size, material, surface condition, loading method and transportation distance. Appropriate protection should be used to reduce the risk of moisture, corrosion, impact and deformation during handling and sea or land transportation. For project orders, packaging and marking requirements can be specified before shipment.

Third-party inspection can be considered according to the purchase order and agreed inspection plan. Independent inspectors may review material documentation, traceability, dimensions, visual condition, testing records, marking and packing before shipment, depending on the inspection scope.

For project orders, communication should cover specification confirmation, production status, inspection arrangements, final documentation, packing and shipment. Clear communication at each stage helps customers coordinate procurement schedules, inspection activities and site delivery requirements more efficiently.

Quality control should cover the product from material verification through manufacturing, dimensional inspection, testing, marking and final documentation. Inspection requirements are established according to the product specification, customer requirements and applicable standards to help ensure that the delivered products meet the agreed technical requirements.

Material certification can be provided according to the product and purchase-order requirements. Where applicable, the material certificate should correspond with the supplied material grade and heat number so that the product can be traced back to the relevant material records.

Material traceability links the finished component to its material grade and relevant production or inspection records, typically through heat or lot identification and supporting documentation. Proper traceability helps engineering, quality and procurement teams verify the material supplied and supports inspection, project documentation and non-conformance control.

Third-party or customer-appointed inspection can be supported when specified in the purchase order or inspection plan. Depending on the agreed scope, inspection may include document review, material identification, dimensional verification, visual inspection, testing, marking, packing and final release documentation.

Certification and compliance requirements depend on the product, material, destination and project specification. Relevant certifications and standards should be confirmed against the current certificate scope and the specific product being supplied. Where applicable, customers may request supporting documentation for quality management, product compliance, material certification and inspection.

The risk of non-conformity is reduced by confirming the technical requirements before production and maintaining inspection records throughout the manufacturing process. Dimensional verification, material identification, documentation review and final inspection help identify potential deviations before shipment.
