常见问题

关于标准、材质、交期、付款与包装的常见疑问，先在这里找答案。

你们能按哪些标准生产法兰？Which flange standards can you produce to?

常做 ASME/ANSI B16.5、B16.47、B16.36，EN 1092-1，DIN 2573/2576/2632/2633，JIS B2220，BS 4504，GOST 12820/12821，UNI 2277/2278 等。客户提供标准号、口径、压力等级、材质与密封面形式即可报价，也可按图纸定制非标法兰。

We regularly produce to ASME/ANSI B16.5, B16.47 and B16.36, EN 1092-1, DIN 2573/2576/2632/2633, JIS B2220, BS 4504, GOST 12820/12821 and UNI 2277/2278. Just send us the standard, size, pressure rating, material and facing type for a quotation, or supply a drawing for a custom non-standard flange.
最小起订量（MOQ）是多少？What is your minimum order quantity?

常规标准规格以整托或整箱起订，通常 1 吨或 100 件起；小批量试单可以先按样品或混合规格拼柜。大口径与非标定制法兰因需单独开料，起订量会相应提高，具体以报价为准。

For standard sizes we normally start at one pallet or one case, typically 1 tonne or 100 pieces. Trial orders can be mixed across sizes to fill a container. Large diameter and custom flanges require dedicated material, so the minimum will be higher - please confirm with your quotation.
交期一般多久？What is the usual lead time?

常备现货规格 7–15 天可发货；常规标准产品大批量订单 20–30 天；大口径或非标定制产品 25–45 天，视开料与热处理排期而定。旺季请提前 2–3 周下单。

Stock sizes ship in 7-15 days. Standard products in large volumes take 20-30 days. Large diameter or custom items take 25-45 days depending on cutting and heat treatment scheduling. During peak season please place orders 2-3 weeks earlier.
可以提供哪些材质和检测报告？What materials and inspection reports do you provide?

碳钢 A105、A350 LF2、Q235、20#；不锈钢 304/304L、316/316L、321；合金钢 F1、F5、F9、F11、F22、F91；双相钢 F51/F53/F55。随货可提供材质证明书、化学成分与力学性能报告、热处理记录、尺寸检测报告，并可安排 SGS、BV、TUV 等第三方检验。

Carbon steel A105, A350 LF2, Q235 and 20#; stainless 304/304L, 316/316L and 321; alloy F1, F5, F9, F11, F22 and F91; duplex F51/F53/F55. Material certificates, chemical and mechanical property reports, heat treatment records and dimensional inspection reports are supplied with the goods, and third-party inspection by SGS, BV or TUV can be arranged.
你们怎么包装？会不会生锈？How do you pack the goods - will they rust?

法兰表面先做防锈处理（防锈油、黑漆或镀锌，按需选择），再用塑料膜或编织袋包覆，装入熏蒸木箱或托盘并使用钢带固定。箱内附装箱单与材质书，箱外按客户要求刷唛头。海运长途运输可选加厚包装。

Flanges receive rust-preventive treatment first (rust oil, black paint or galvanizing as required), are wrapped in plastic film or woven bags, then packed into fumigated wooden cases or pallets secured with steel strapping. A packing list and material certificate go inside, and shipping marks are stencilled outside to your instructions. Heavy-duty packing is available for long sea voyages.
付款方式与贸易条款是什么？What are your payment terms and trade terms?

常规为 30% 预付款 + 70% 尾款见提单副本；老客户与长期合作可协商。贸易条款支持 EXW、FOB、CIF、CFR、DDP，接受 T/T、即期信用证（L/C at sight）等方式。

Our standard terms are 30% deposit with the 70% balance against copy of the bill of lading; other arrangements can be discussed for repeat customers. We work on EXW, FOB, CIF, CFR and DDP terms and accept T/T and L/C at sight.
样品怎么收费？多久能寄到？How much are samples and how fast can they arrive?

常规规格样品可免费提供 1–2 件，客户只需承担快递费用。样品一般 3–7 天内寄出，国际快递 3–7 个工作日到达，可走 DHL、FedEx、UPS 或客户指定账号。

For standard sizes we can provide one or two samples free of charge - you only cover the courier cost. Samples are usually dispatched within 3-7 days and arrive in 3-7 working days by DHL, FedEx or UPS, or on your own courier account.
第一次合作，怎么确认你们的质量？This is our first cooperation - how can we be sure of the quality?

可以先下小批量试单，我们提供全过程照片与视频、首件检测数据；也可安排第三方验货机构驻厂检验。合作稳定的客户可选择年度框架协议，由我们备料与备库，缩短交期。

Start with a small trial order. We will provide production photos and videos throughout and first-article inspection data, and a third-party inspection agency can be arranged to inspect at our factory. Established customers can set up an annual framework agreement so we hold material and stock to shorten lead time.
