Two-Hole Galvanized Pipe Strap

JOYEAR's two-hole galvanized pipe clamp is a single-piece, stamped metal component fabricated from hot-dip galvanized steel, featuring a bright, rust-resistant galvanized finish. The central section consists of a curved, wrap-around band designed to fit snugly against the pipe's exterior, with the size specification embossed directly onto the body. Symmetrical mounting tabs extend from both sides of the band, each featuring a dedicated circular installation hole and chamfered, smooth-edged corners. The component is formed through bending and riveting processes to ensure structural integrity, securing the pipe in place via the two mounting tabs.

As this is a non-standard stamped fastener, we offer full customization services. Please note that accurate mold creation cannot be achieved based solely on photographs of existing samples. To ensure precise cost estimation, mold fabrication, and the production of finished goods that meet your exact requirements, customers must provide comprehensive engineering drawings detailing all technical specifications-including inner diameter, material thickness, bending angles, mounting hole locations, overall dimensions, coating requirements, and embossed markings.

To ensure that the pipe clamps you order are 100% compatible with your working conditions and to avoid returns or project delays due to mismatched specifications, please provide the following parameters using our "5-Step Confirmation Method" before you request a quote or place an order. We are committed to recommending the optimal solution based on your actual working conditions, not just selling off-the-shelf stock.

●Step 1: Confirm Pipe Installation Dimensions

Under the same Nominal Diameter (DN), the OD can vary by 3-5mm between GB, ANSI, and JIS standards.

● Step 2: Confirm the Service Environment

Choosing the wrong environment is the root cause of rust and failure. Hot-dipped galvanizing is mandatory for outdoor/coastal areas. The cost is slightly higher, but the lifespan is several times longer.

►Dry indoor – Electro-galvanized, bright silver, 5-8μm, ≥24H salt spray

►Humid indoor – Electro-galvanized with passivation, 8-12μm, ≥72H

►Outdoor/coastal/chemical – Hot-dipped galvanized, dull grey, ≥70μm, ≥500H

►Extreme high-temp or strong acid/alkali – HDG + epoxy coating, customized

● Step 3: Confirm Pipe Material

If the clamp is used on Copper, Stainless Steel Thin-wall, or Plastic Pipes, a rubber cushion is mandatory. Otherwise, vibration friction will wear through the pipe wall or cause galvanic corrosion.

► GI or black iron pipe – Plain, no liner, metal-to-metal contact, strong anti-slip, lowest cost

► Copper, stainless steel, or PPR – EPDM rubber cushion, isolates galvanic corrosion, damping, noise reduction, protects pipe wall

► Insulated pipes – Insulated liner pad, custom thickened, prevents thermal bridging and damage to insulation

● Step 4: Confirm Mounting Hole Specs

Standard hole sizes fit M8 bolts. If your bracket holes are special, please fill out this section carefully.

► Mounting hole diameter: ______ mm – Standard: 8.5mm for M8, 10.5mm for M10

► Hole center-to-center distance: ______ mm – Critical! Must align with bracket holes. Please specify if slotted holes are needed.

● Step 5: Confirm Applicable Standards & Certifications

If your project requires Fire Safety Inspection or supervision by a foreign owner, please check this box.

►China National Standard 

• GB/T 17116.1 / GB/T 23257. We provide Mill Test Certificate & Type Test Report.

►American/International Standard

• MSS SP-69 / UL 203. Steel grade meets ASTM A653, advanced notice required.

" If you find the process too cumbersome, you can simply provide the product drawings. " 

Get drawings from customers, or design drawings according to customers' detail requests or sample.

The two parties confirm the details of the drawings and product raw materials, surface treatment, etc.

Make first samples and inspect them according to the drawing strictly.

Send to the customer for approval after internal approval.

Strictly produce the goods as per the drawings and first samples. Packed well after final inspection and ship to customers.

Shipping plan departing from Ningbo Port (FOB)

• Option 1: Ocean Freight – Full Container Load (FCL)
• Option 2: Ocean Freight – Less than Container Load (LCL)
• Option 3: Air Freight – Emergency Express
• Option 4: China-Europe Railway Express (Rail Freight) – For Europe Only
• Option 5: International Express (DHL/UPS/FedEx) – For Samples or Small Parcels

JOYEAR's Recommendations

● Bulk regular orders:

► We strongly recommend Full Container Load (FCL, Option 1). This is the most economical choice given the "heavy cargo" nature of pipe clamps. We will ensure proper anti-rust packaging (using VCI paper or stretch film) to protect against rust during several weeks at sea.

● For small urgent orders to Europe:

► We recommend the China-Europe Railway Express (Option 4). It is faster than sea freight and much more affordable than air freight.

● For emergency replacement parts (weight < 200kg):

► We recommend Air Freight (Option 3) or International Express (Option 5). We can assist in adjusting the declaration value (e.g., lowering the declared value) to help you save on import duties.

● For small quantities to North America:

► Only Less than Container Load (LCL, Option 2) is available. Please be sure to request that we add honeycomb cardboard edge protectors on the cartons to withstand rough handling during LCL consolidation.
