Buy & Import Precision machined stainless tube sheet from Zhangqiu Yubin Petrochemical Fitings Factory - Wholesale Supply

The precision machined stainless tube sheet is a heavy‑duty plate used in shell‑and‑tube heat exchangers. It is fabricated from either 316L or 304L stainless steel, with thickness options ranging from 10 mm to 80 mm. Each sheet is drilled with accurately positioned tube holes to meet ASME Section VIII and TEMA design codes. The finished product carries mill test certificates and complies with international corrosion‑resistance requirements.

Grade 316L offers superior resistance to chloride environments, while 304L provides a cost‑effective alternative for less aggressive media. In the heat‑exchanger industry, typical surface finish for tube sheets is Ra 0.4 µm, enabling efficient heat transfer. Tolerances on hole diameter are commonly held within ±0.02 mm, ensuring a tight fit with tube bundles. These specifications align with standard practice for petrochemical, power generation and oil‑refining sectors.

Buyers such as plant engineers, EPC contractors and equipment integrators source these sheets for new installations or retrofit projects. The supplier offers export‑ready units with wood‑crate packaging and can provide documentation on request. Trade terms, minimum order quantities and Incoterms should be confirmed directly with the factory before placing an order.

Frequently Asked Questions About Precision machined stainless tube sheet from Zhangqiu Yubin Petrochemical Fitings Factory
The factory offers both 316L and 304L grades. Grade 316L provides higher chloride resistance, while 304L is suitable for less aggressive environments; buyers can specify the required grade on the order.

Sourcing Precision machined stainless tube sheet from Zhangqiu Yubin Petrochemical Fitings Factory - China Import Guide

Before confirming a purchase, importers should obtain the detailed drawing that shows hole pattern, diameter and sheet dimensions, and verify that the stainless‑steel grade matches the project specification. Request the mill test certificate and, if required, a chemical analysis report to confirm alloy composition. It is also prudent to ask for a sample of the surface finish to ensure the Ra 0.4 µm level meets heat‑transfer expectations.

Logistics planning should clarify the preferred Incoterm, with FOB Tianjin and CIF Shanghai being common for Chinese exporters. Typical lead times for tube‑sheet production range from two to four weeks after final drawing approval, but the exact schedule must be confirmed with the factory. Payment methods such as irrevocable L/C at sight or T/T against documents are usually accepted, yet buyers need to verify the supplier’s banking details before remittance.

Quality assurance normally includes a third‑party inspection of dimensions, hole tolerance and surface finish before loading. Importers can arrange for a pre‑shipment audit or request a post‑production inspection report to be sent electronically. All relevant certificates, including the mill test certificate, material test report and compliance documents, should be compiled and reviewed alongside the commercial invoice to facilitate customs clearance.
