Stainless Water Pipes
Thin-wall stainless steel water pipe and fittings for building and municipal water supply from Xinhui, Jiangmen — double-press, ring-press, grooved and socket-weld systems, DN15–DN650 by the company's catalogue. Registry-read active since 2006 with RMB 120 million fully paid-in and manufacturing in scope; a controlling subsidiary of listed stainless producer Yongjin (603995). Import and export is not in the scope wording, and no WRAS, DVGW, NSF 61 or WaterMark approval is on record.
Six connection systems, DN15 to DN650.
Double-Press System (National Standard)
Thin-wall stainless pipe with double-press fittings to Chinese national standards — the company’s main line for building water supply. Sizes, pressure ratings and seal material are not published on the website; ask for the size table and the seal compound (EPDM for potable water is usual).
Double-Press System (European Profile)
A separate double-press series described by the company as to European standard. No DVGW, WRAS or KIWA approval is on record, and the profile (M or V) and pipe standard (EN 10312) are not stated — ask before specifying it for a European project.
Ring-Press System
Ring-press (环压) fittings to Chinese national standards, a joining method common in Chinese residential and commercial risers. Ask whether the ring-press line is offered with any overseas approval.
Grooved Connection System
Roll-grooved thin-wall stainless pipe and grooved couplings, typically used for larger diameters and plant-room pipework. The upper size, working pressure and coupling source are not stated — ask.
Socket-Weld Fittings
Socket-weld stainless fittings for thin-wall pipe. Ask for the weld procedure, whether fittings are supplied solution-annealed and pickled, and the pressure test record.
Stainless Liquid-Cooling Manifolds
Listed on the website as a stainless liquid-cooling pipework integration series — relevant to data-centre and equipment cooling loops. No specification, reference or pressure rating is published; ask for drawings and test records if this is the line you need.
What the registry confirms, and what stays open.
What the Scope Says
The registered scope, read on 2026-09-22 and quoted without change, is 不锈钢流体输送用管及配件、阀门、净水设备的销售。^不锈钢流体输送用管及配件、阀门、净水设备的生产；机电设备安装 (sale and production of stainless steel pipe and fittings for fluid conveyance, valves and water-purification equipment; installation of mechanical and electrical equipment). Manufacturing is in scope.
Import & Export: Not in the Scope Wording
The registered scope wording does not include import and export. The background check supplied to CMH states that the company holds import and export rights; CMH has not seen the customs registration. Ask for the customs consignor / consignee registration and a recent export declaration before the first shipment.
Listed Parent, Capital Fully Paid
Registered capital RMB 120 million, fully paid-in (registry). Yongjin (SSE 603995), a listed producer of cold-rolled stainless strip, announced in September 2023 the purchase of a 51% controlling stake; the background check records its holding at 68.20% now. The parent’s strip is the natural raw material for thin-wall water pipe — ask whether mill certificates trace to it.
Office in Shenzhen, Plant in Jiangmen
The registered address is an office unit in the Guangming watch-industry park, Shenzhen. Manufacturing is at the company’s own base in Siqian Town, Xinhui, Jiangmen, which the company describes as over 140,000 m² with 40+ pipe lines and 80+ fitting lines. Plant audits have to be done in Jiangmen, not at the registered address.
Court Records: Current vs. Historical
Current record: two court-hearing notices and two court announcements. Historical record: 16 published judgments, 27 case filings, three enforcement cases and one terminated enforcement case, all historical. The background check describes the cases as mainly sales-contract and receivable disputes and finds no current dishonest-debtor listing, consumption restriction or active major enforcement. Agree payment terms and warranty clauses in writing.
Domestic Approvals Claimed, Overseas Approvals Absent
The background check lists a drinking-water product hygiene licence, a special-equipment pressure piping element manufacturing licence, high-tech enterprise status and ISO 9001 / 14001; the website states ISO 9001, ISO 14001, a CNAS-accredited laboratory and 132 patents. None of those documents has been sighted by CMH, and no WRAS, DVGW, NSF/ANSI/CAN 61, WaterMark or SASO certificate is on record.
What was checked — and what the check found.
The registry facts on this page — status, capital and paid-in, address, staff range, scope wording and the court-record counts — come from a first-hand registry and risk read by CMH on 2026-09-22; the credit code’s check digit was recomputed by CMH. Product families, sizes, capacity, staff numbers, patents, ISO and the CNAS laboratory are the company’s own statements on its website. The hygiene licence, pressure-piping licence, high-tech status, export rights and the parent’s current holding come from a background check supplied to CMH for onboarding. Yongjin’s 2023 purchase of a 51% stake is from its public announcement. No certificate, licence, test report or export declaration has been sighted, and the plant has not been visited by CMH. This page is updated when documents arrive.
A stainless water-pipe maker since 2006, read off its registry check.
Minle is Shenzhen Minle Pipe Industry Co., Ltd. (深圳市民乐管业有限公司), registered in Shenzhen on 17 April 2006. A first-hand registry read on 2026-09-22 confirms active (存续) status, registered capital of RMB 120 million fully paid-in, a staff range of 100–499, and a scope covering the production and sale of stainless steel fluid-conveyance pipe and fittings, valves and water-purification equipment. The registered address is an office unit in Guangming, Shenzhen; manufacturing is at the company’s own base in Siqian Town, Xinhui, Jiangmen.
By its own website the company runs 40+ pipe lines and 80+ fitting lines, makes 45,000 tonnes of pipe and 35 million fittings a year, employs 400+ people, holds 132 patents, and covers DN15 to DN650 across double-press, ring-press, grooved and socket-weld systems. In September 2023 the listed stainless-strip producer Yongjin (SSE 603995) announced the purchase of a 51% controlling stake, which puts a raw-material producer directly behind the pipe mill.
Three things are open. Export: import and export is not in the registered scope wording; ask for the customs registration. Approvals: no WRAS, DVGW, NSF 61, WaterMark or SASO certificate is on record, and the Chinese hygiene and pressure-piping licences listed in the background check have not been sighted. Records: current court notices and a historical enforcement record are disclosed above. Ask for all three before relying on the listing.

Frequently Asked Questions
What does Minle make?
Thin-wall stainless steel water pipe and matching fittings for building and utility water supply: double-press and ring-press systems to Chinese national standards, a double-press series it describes as European-profile, grooved and socket-weld connections, general parts, and a stainless liquid-cooling manifold line. The company’s catalogue covers DN15 to DN650. Water supply is its main business, not a side line.
Is this listing CMH-verified?
Yes, on the registry check: active since 2006, RMB 120 million fully paid-in, and a scope that covers the production of stainless fluid-conveyance pipe and fittings. It does not confirm the plant, the capacity, the licences or any certificate — none was supplied, and the Jiangmen plant has not been visited by CMH.
Can Minle export directly?
Not confirmed. The registered scope wording does not include import and export. The background check supplied to CMH states that the company holds import and export rights and has export experience. Ask for its customs consignor / consignee registration and a recent export declaration, or agree which party is the exporter of record, before placing the first order.
Who owns Minle?
Yongjin (Shanghai Stock Exchange 603995), a listed producer of cold-rolled stainless steel strip, announced in September 2023 that it would buy a 51% stake for RMB 83.23 million, making Minle a controlling subsidiary. The background check records the holding at 68.20% now; confirm against the latest registry record. Individual shareholders are not named on this page.
Is there anything negative on the record?
Yes, and it is disclosed in two parts. Current: two court-hearing notices and two court announcements. Historical: 16 published judgments, 27 case filings, three enforcement cases and one terminated enforcement case. The background check describes them as mainly sales-contract and receivable disputes and finds no current dishonest-debtor listing, consumption restriction or active major enforcement. Put payment terms and warranty in writing.
Which drinking-water approvals will a buyer ask for, and does Minle hold them?
By market: United Kingdom — WRAS approval under the Water Supply (Water Fittings) Regulations; Germany — DVGW (the tube standard for potable-water stainless tube in Europe is EN 10312); United States — NSF/ANSI/CAN 61 for drinking-water contact; Australia — WaterMark certification. None of these is on record for Minle. Its European-profile double-press line should not be specified for those markets until an approval is shown.
What does Saudi Arabia require for stainless water pipe and fittings?
SASO’s Technical Regulation for Building Materials, Part 5: Pipes used in Water, Electricity and Gas Networks (document 02-06-19-171, sighted 2026-09-22 on saso.gov.sa) lists welded circular stainless steel pipes (HS 7306) and pipe fittings (HS 7307) among the products it covers; compliance is shown through a product certificate and a shipment certificate issued on the SABER platform. The regulation states that a plant certified to ISO 14001 is considered to meet its environmental-management requirement — Minle states it holds ISO 14001 (certificate not sighted). No SABER certificate is on record.
Are there trade remedies on Chinese stainless pipe in the United States?
Yes, for one product definition. Antidumping and countervailing duty orders on circular welded austenitic stainless pressure pipe from China (outside diameter up to 14 inches; cases A-570-930 and C-570-931) were continued by notice in the Federal Register of 28 May 2025. The orders exclude, among others, mechanical tubing to ASTM A-554 and tubing to ASTM A-269 / A-270. Whether a given thin-wall plumbing tube falls inside the scope depends on its specification — obtain a scope ruling before importing. Fittings (HS 7307) are a separate classification. This is not customs advice.
