Can you produce graphite parts according to customer drawings?

Yes. Custom machining according to customer 2D/3D drawings is supported.

Do you offer custom-made graphite components for small-batch or one-off orders?

Yes. Small-batch and one-off production are available for prototyping, replacement, and trial production.

What file formats are acceptable for drawing processing?

Common formats: STEP, IGS, PDF, DWG.

What is your typical lead-time for graphite heat exchanger?

Typically 50 working days; complex or large orders are negotiable.

Can you provide material test certificates for graphite products?

Yes. Material certificates, inspection reports, and dimensional reports can be provided.

Are graphite products subject to export control / dual-use items regulation?

Some high-purity, high-strength, nuclear-grade, or specific graphite items may be subject to export control. Confirmation depends on material, specification, end use, and destination country.

What documents will you provide for customs clearance of graphite shipments?

Commercial invoice, packing list, certificate of origin, material certificate, MSDS, declaration elements, etc., according to destination requirements.

Are graphite parts fragile and easy to get damaged during transit?

Graphite is brittle. Edges, thin walls, and tube openings are vulnerable; professional shock-proof packaging is required.

What kind of packaging do you use for graphite components shipment?

EPE/foam cushioning + wooden case or pallet + metal frame reinforcement to prevent impact, chipping, and cracking.and customer‑specified packaging methods

How should graphite parts be stored before installation?

Store in a dry, flat, pressure-free, impact-free area. Avoid moisture, stacking pressure, and sharp-object collision.

Do you offer onsite technical guidance for graphite parts assembly?

Remote guidance is available. For major projects or complex assembly, on-site technical support can be negotiated, with fees agreed upon by both parties in the contract.

How can engineers quickly identify adhesive layer aging and failure in the field?

Upon disassembly, inspect whether the adhesive layer has become brittle, carbonized and blackened, pulverized, or exhibits blistering caused by media swelling.

When pressure drop rises, how do you distinguish between crystallization clogging and resin swelling bore reduction?

Attempt circulation flushing with warm water or a designated solvent. If pressure drops normalize, it is crystallization; if pressure drops remain unchanged, it is irreversible resin swelling or hardened scale.

What are the visual identification features of thermal shock-induced graphite cracking?

Thermal shock cracks tend to be straight and highly penetrating, lacking obvious corrosive thinning or discolored edges, and frequently appear at cross-sectional geometric transitions or high thermal stress corners.
